Anthony Kay

White Sox, Anthony Kay Agree To Two-Year Deal

By Steve Adams | December 3, 2025 at 11:15am CDT

The White Sox and left-hander Anthony Kay are reportedly in agreement on a two-year, $12MM contract. The former first-round pick and top prospect, who’s represented by CAA, will be paid $5MM in each of the next two seasons and has a $2MM buyout on a $10MM mutual option for the 2028 season. He can earn another $1.5MM via incentives. Kay has spent the past two seasons pitching well for the Yokohama DeNA BayStars of Japan’s Nippon Professional Baseball.

It’s a familiar page in general manager Chris Getz’s playbook: sign a former first-rounder to a two-year deal on the heels of a strong run pitching in one of the top leagues in Asia.

That strategy worked out reasonably well when Chicago signed Erick Fedde for two years and $15MM in the 2023-24 offseason following a terrific season in the Korea Baseball Organization; Fedde was traded to the Cardinals in a three-team swap in July 2024, netting the White Sox Miguel Vargas and minor league infielders Alexander Albertus and Jeral Perez. Vargas was a league-average bat for the South Siders in 2025 and is controlled another four seasons. Albertus and Perez rank within the top 25 prospects in the Sox’ system.

The Sox will hope for similar results in their similarly priced investment into Kay. The 30-year-old southpaw (31 in March) has pitched 291 2/3 innings since heading to Japan. In that time, he’s logged a 2.53 ERA with a 20.9% strikeout rate, 7.9% walk rate and 54.5% ground-ball rate in 48 starts out of the BayStars’ rotation.

Kay has changed his pitch repertoire since moving to NPB. He sat 94.1 mph with a four-seamer, 87.9 mph with a cutter and 86.2 mph with a slider during his limited big league work from 2019-23. He’s added about three miles per hour to that cutter and also begun throwing a sinker that he didn’t have during his last run in North America, which he credits with generating more soft contact. He’s still throwing a sweeper and occasional changeup, and the lefty has also dabbled with a curveball. (He spoke about those changes and more in an October chat with Fansided’s Robert Murray.)

From 2019-23, Kay pitched 85 1/3 innings between the Blue Jays, Cubs and Mets. It was the Mets who originally selected him 31st overall back in 2016, though they were actually the third team for whom he pitched in the majors. New York traded Kay and Simeon Woods Richardson to the Blue Jays in exchange for Marcus Stroman back in 2019, and Kay made his MLB debut not long after the swap.

Things never clicked for Kay in the majors. He’s been tagged for a 5.59 ERA with a solid 22.4% strikeout rate but an ugly 12% walk rate. Opponents averaged 1.27 homers per nine innings against him. He didn’t fare much better in terms of run prevention in parts of four Triple-A seasons, logging a 5.40 earned run average in 148 1/3 innings pitched.

As we saw with Fedde and with yesterday’s three-year, $30MM deal between the Blue Jays and Cody Ponce, what Kay did in his prior MLB work holds virtually no bearing on his newfound payday. He’s a different pitcher now than he was at any point in 2019-23, and the White Sox are paying him based on the their belief that the changes he’s implemented while pitching in Yokohama will beget better results back in Major League Baseball.

There’s inherent risk, but at this price point, it’s also hard to fault a White Sox club that’s still in the midst of a rebuilding effort. Kay will either pitch well, at which point he’d emerge as a nice trade chip, or he’ll continue to struggle and the Sox will be out a relatively modest $5MM per season. The overall scope of this commitment is less than the $15MM paydays we saw for aging veterans in their late 30s/early 40s last year (e.g. Charlie Morton, Max Scherzer, Justin Verlander, Alex Cobb). It’s a life-changing deal for Kay but a small-scale gamble for the team.

Kay steps into a rotation mix that has plenty of options but is lacking when it comes to established contributors. Right-handers Shane Smith, Sean Burke and Davis Martin all pitched between 134 and 146 innings with ERAs between 3.81 (Smith) and 4.22 (Burke). None of the three has more than one full season of big league success. Smith was a Rule 5 pick at last year’s Winter Meetings and a rookie in 2025.

Those four are now favored to open the year in manager Will Venable’s rotation. Jonathan Cannon is tentatively penciled into the fifth spot for the time being, but he struggled greatly in 2025 and has minor league options remaining. Prospects Ky Bush and Drew Thorpe could be midseason options as they work their way back from Tommy John surgery performed last spring. Lefties Noah Schultz and Hagen Smith rank among the game’s top pitching prospects and could be ready at some point next summer as well.

There’s still room for the Sox to add some veteran innings. Getz has previously voiced a reluctance to commit to free agents beyond the 2026 season — though he did so with Kay, albeit in moderate fashion. There ought to be plenty of veteran arms looking at one-year deals, whether that’s a back-of-the-rotation innings eater (e.g. Michael Lorenzen, Patrick Corbin) or an upside play coming off an injury or poor performance (e.g. Nestor Cortes, Walker Buehler, Dustin May). The White Sox’ payroll currently projects at just $68MM, per RosterResource, so there’s room for Getz & Co. to bring in several additions to fill out the rotation, bullpen, outfield and infield.

Murray first reported that the two parties had agreed to a two-year, $12MM deal. The Athletic’s Will Sammon added details about the specific breakdown and incentives.

Anthony Kay Likely To Pursue MLB Opportunity This Offseason

By AJ Eustace and Leo Morgenstern | October 22, 2025 at 10:04pm CDT

Former MLB pitcher Anthony Kay is expected to come back stateside in 2026, per Jon Heyman of the New York Post. The left-hander spent the past two seasons pitching for the Yokohama DeNA BayStars of the Nippon Professional Baseball league in Japan.

Kay, 30, was the Mets’ first-round draft pick in 2016. He was traded to the Blue Jays in 2019 as part of the deal that sent Marcus Stroman to New York. The Long Island native would debut later that year and spend four seasons in Toronto, maxing out at 33 2/3 innings in 2021. He then had brief stints with the Cubs and Mets in 2023, and he spent about two weeks with the Athletics following the 2023 campaign; the A’s claimed him off waivers in late October, but he elected free agency after they removed him from their 40-man roster in early November. Altogether, Kay pitched to a 5.59 ERA in 85 1/3 big-league innings from 2019-23, posting a 22.4% strikeout rate and a 12.0% walk rate.

He has seen better results in Japan in each of the past two years. In 2024, Kay posted a 3.42 ERA in 136 2/3 innings for the Bay Stars while striking out 20.2% of hitters and walking 9.0%. His 0.40 home runs allowed per nine innings (HR/9) was especially impressive. Only six Central League pitchers (min. 100 IP) gave up home runs at a lower rate. At the end of the year, Kay helped the BayStars to their first Japan Series victory since 1998, pitching seven scoreless innings and collecting the win in Game 4.

His first season in NPB was no doubt a success. With that said, it’s worth keeping in mind the lower run-scoring environment in Japan; the league average ERA in the Central League in 2024 was 2.88, well below Kay’s 3.42 mark. However, in 2025, his numbers spoke for themselves. He deployed a deep and diverse arsenal to post a 1.74 ERA in 155 innings, cutting his walk rate to 6.8%. The southpaw led all NPB starting pitchers with a 21.9% strikeout rate, while his ERA ranked second, and his 0.46 HR/9 was tied for fourth. He wasn’t just solid; he was dominant.

Following such a strong season, it makes sense that Kay would look to return to Major League Baseball. He may not have garnered much attention on the open market two years ago, but he’s bound to have more suitors now after proving he could thrive as a starting pitcher against high-level competition.

Anthony Kay To Sign With NPB’s Yokohama BayStars

By Anthony Franco | January 9, 2024 at 11:04pm CDT

Left-hander Anthony Kay is signing with the Yokohama BayStars of Japan’s Nippon Professional Baseball, reports Robert Murray of FanSided (X link). It’ll be the first overseas stint for the CAA client.

Kay, 29 in March, is a former first-round pick of the Mets. Traded to the Blue Jays as a prospect in the Marcus Stroman deal, he debuted with Toronto in 2019. That kicked off a stretch of five seasons with some amount of MLB action. His largest workload came in 2021, when he logged 33 2/3 innings of 5.61 ERA ball.

The UCONN product remained with the Jays through the 2022 season. He bounced around the league last year, going to three different teams on waivers. Kay opened the season with the Cubs and briefly landed with the Mets at year’s end. During the postseason, the A’s claimed him. Oakland cut him loose a couple weeks later without any game action, sending him to the open market.

Kay has yet to find much MLB success. He owns a 5.59 ERA through 85 1/3 innings, working mostly in a long relief capacity. Middling control has been the primary culprit. Kay has walked upwards of 12% of batters faced in his MLB career. He handed out free passes at a 13.6% clip during his big league work last season and walked a nearly identical 13.7% of opponents over 37 1/3 innings in Triple-A.

Strike-throwing issues notwithstanding, Kay represents an intriguing flier for an NPB team. His fastball has averaged just under 95 MPH during his time in the majors. He has a reasonable 22.4% strikeout percentage in his big league career and fanned more than 31% of opposing hitters in Triple-A a year ago.

That ability to miss bats would’ve enabled Kay to find a minor league contract if he wanted to remain in affiliated ball. The opportunity in Japan allows him to lock in a salary that is surely above what he’d have made in Triple-A. He’ll take that avenue instead. If he pitches well in NPB, he could reemerge as a target for major league teams a year or two from now.

Athletics Claim Miguel Andujar From Pirates

By Darragh McDonald | November 6, 2023 at 4:06pm CDT

The Athletics announced that they have claimed infielder/outfielder Miguel Andujar off waivers from the Pirates and selected outfielder Lazaro Armenteros. The A’s also outrighted left-handers Anthony Kay and Easton Lucas, as well as right-handers Tayler Scott and Chad Smith to Triple-A Las Vegas. The move on Armenteros was reported last week.

Andujar, 29 in March, had a tremendous season with the Yankees in 2018, finishing second in Rookie of the Year voting to Shohei Ohtani. But since then, he hasn’t been given an extended stretch of playing time in the big leagues. Shoulder surgery put him out of action for much of 2019 and Gio Urshela stole the third base job in the Bronx while he was gone. Since then, he has generally crushed in the minors but struggled when given brief looks in the majors.

2023 continued that pattern, with Andujar in the Pirates organization. He was up in the majors for a couple of weeks from late April to mid-May but hit just .161/.212/.387. But his Triple-A season was far stronger, as he hit .338/.404/.536 at that level. He got back to the big leagues as a September call-up and was able to post an excellent line .302/.351/.528 in the final month of the season.

Given that encouraging finish, the Bucs could have held onto Andujar but he was projected for an arbitration salary of $2.2MM and is out of options. He was also limited to playing first base and the outfield corners in 2023, both in the majors and in the minors. The Pirates decided to move on but the A’s have come in to claim him.

The latter club has traded away their most established big leaguers in recent years, which perhaps makes Oakland the ideal landing spot for Andujar. He will be competing for playing time in the first base/corner outfield/designated hitter mix with Ryan Noda, Seth Brown, Brent Rooker, JJ Bleday and others. If he is finally able to click in the majors again, he can be retained for another season via arbitration, though the A’s would likely trade him in that scenario.

Kay, 28, was just claimed off waivers a couple of weeks ago. He has a 5.59 ERA in 85 1/3 career innings at the major league level. He tossed 40 2/3 innings in the minors this year, between the Mets and Cubs, with a 3.76 ERA in that time.

Lucas, 26, just came of the A’s in the deadline deal that sent Shintaro Fujinami to the O’s. He was added to the roster in early September and made his major league debut, allowing six earned runs in 6 2/3 innings. He tossed 46 2/3 frames in the minors for the year across different levels and organizations, with a 3.86 ERA across those clubs.

Scott, 31, was claimed off waivers from the Red Sox in July. He had a 5.60 ERA in the majors in 2023, splitting time between three different clubs. Between three different Triple-A clubs, he logged 38 1/3 innings with a 1.64 ERA.

Smith, 28, was acquired from the Rockies in the last offseason. He went on to throw 13 2/3 innings for the A’s in 2023 with a 6.59 ERA. His 34 2/3 innings in Triple-A didn’t go any better, with a 7.53 ERA in that time.

A’s Claim Anthony Kay

By Anthony Franco | October 24, 2023 at 3:47pm CDT

The A’s announced they’ve claimed lefty reliever Anthony Kay off waivers from the Mets. New York had attempted to outright him off the 40-man roster last week.

Kay, a UCONN product, was selected by the Mets with the #31 pick in the 2016 draft. The Mets sent him to the Blue Jays as part of the Marcus Stroman deal. Kay pitched parts of four seasons with the Jays, working to a 5.48 ERA through 70 2/3 innings. Toronto lost him on waivers to the Cubs last offseason.

While Chicago quickly ran Kay through waivers themselves, they added him back to the roster in mid-June. He pitched 13 times for the Cubs, allowing eight runs in 11 1/3 innings. The Mets snagged him back via waivers with a couple weeks left in the season. He made four appearances with his original organization, working 3 2/3 frames of three-run ball to close the year. Kay’s fastball sat just under 95 MPH on average, yet he managed just an 11:9 strikeout-to-walk ratio between the two clubs.

The 28-year-old has yet to find much major league success. He has allowed 5.67 earned runs per nine, striking out an average 22.4% of batters faced against a lofty 12% walk rate. Kay showed some intriguing swing-and-miss numbers in Triple-A this year, combining for a 3.76 ERA while fanning over a third of opponents in 40 2/3 frames. While a 13.3% walk percentage still hints at real control woes, the solid minor league season and his decent velocity intrigued the A’s front office.

Kay is out of options, so the A’s can’t send him to the minors without first running him through waivers (at which point he’d have the ability to elect free agency). If they keep him on the 40-man roster all offseason, he’d need to secure a job in the MLB bullpen.

Mets Place Six Players On Outright Waivers

By Darragh McDonald | October 20, 2023 at 6:00pm CDT

The Mets have placed six players on outright waivers, per Anthony DiComo of MLB.com. They are left-hander Anthony Kay, right-hander Vinny Nittoli, catcher Michael Pérez, outfielder Rafael Ortega, and infielders Danny Mendick and Jonathan Araúz. This will open six spots on the club’s 40-man roster. As noted by DiComo, each player will have the right to elect free agency if they pass through waivers unclaimed.

Kay, 28, was only with the Mets a short time, coming over from the Cubs in mid-September via a waiver claim. Between the two clubs, he tossed 14 2/3 innings with a 6.14 earned run average. He was much better in the minors, with a 3.76 ERA in 40 2/3 Triple-A innings this year. He will be out of options next year.

Nittoli, 33 next month, was also a midseason acquisition from the Cubs. He opted out of his minor league deal and was flipped to the Mets for cash in early June. He spent most of the rest of the season on optional assignment, only making three appearances at the major league level. He tossed 42 2/3 Triple-A innings between the two organizations with an ERA of 4.64 in that time. He will also be out of options next year.

Pérez, 31, signed a minor league deal with the Mets in the offseason and was added to the roster in May. He got into three games in the big leagues this year, spending most of his time on optional assignment. He hit .204/.309/.352 in 70 Triple-A games, leading to a wRC+ of 66. He, too, will be out of options next year.

Mendick, 30, had an encouraging performance with the White Sox in 2022, hitting .289/.343/.443 for a wRC+ of 125. But that came in just 31 games since he tore the ACL in his left knee in June of that year. The Sox non-tendered him and the Mets decided to take a chance, signing him to a $1MM guarantee. He hit well in the minors this year, slashing .282/.369/.424 in Triple-A, but his 35 major league games resulted in a paltry line of .185/.232/.277.

Araúz, 25, was selected from the Orioles in the minor league portion of the Rule 5 draft. He was selected to the major league roster in August and got into 27 games but hit just .136/.203/.288 in those. His 100 games at the Triple-A level resulted in more palatable line of .239/.340/.415.

Ortega, 32, signed a minor league deal with the Mets in June and was added to the roster at the start of August. He hit .219/.341/.272 in 47 games as the season was winding down for a wRC+ of 83. He had a strong season with the Cubs in 2021, hitting .291/.360/.463, but his career line of .247/.324/.352 translates to a wRC+ of 89.

Most of these players were added to the club late in the year, after they traded away various players at the deadline and needed some fresh bodies to play out the string. None of them were key parts of the long-term plans and they have been removed from the roster in order to give the club some greater flexibility with the offseason set to begin shortly. If they clear waivers, they will become free agents and look to find minor league deals this winter.

NL East Notes: Arraez, Waldrep, Kay

By Mark Polishuk | September 24, 2023 at 5:36pm CDT

The Marlins recorded an important win over the Brewers today, allowing Miami to keep pace in the tight NL wild card race. The Fish won despite Luis Arraez’s absence, as the second baseman didn’t play after making a late exit from Saturday’s game due to a twisted ankle. Arraez had already missed a pair of games this week due to that sore ankle, and exacerbated the problem in somewhat fluky fashion on Saturday. As he told MLB.com and other reporters, Arraez slipped while walking down the dugout steps at the conclusion of the eighth inning, in part because the ballpark had suddenly dimmed the lights for the entrance of closer Tanner Scott.

“It’s frustrating because I need to play….The good thing is I’ve got the day off tomorrow, and then let’s see how I feel the next day,” Arraez said, in reference to Miami’s off-day Monday.

After that break, the Marlins will play their final six games of the regular season — three games against the Mets and three against the Pirates, all on the road. Today’s result notwithstanding, it is hard to imagine the Marlins can push into the playoffs without the Major League batting average leader in the lineup, so Miami fans can only hope that Arraez’s ankle is okay after some rest.

Mets Claim Anthony Kay From Cubs

By Darragh McDonald | September 14, 2023 at 2:55pm CDT

The Mets have claimed left-hander Anthony Kay off waivers from the Cubs, reports Jesse Rogers of ESPN. The latter club had designated the lefty for assignment earlier this week. The Mets already had a vacancy on their 40-man roster and won’t need to make a corresponding move. The Mets have sent Kay to Triple-A for now, per Abbey Mastracco of the New York Daily News.

Kay, now 28, returns to his original organization. The Mets selected him with the 31st overall pick in 2016 but traded him to the Blue Jays alongside Simeon Woods Richardson in the 2019 Marcus Stroman deal. The lefty got brief looks at the big league level while with the Jays but wasn’t able to establish himself and was placed on waivers, getting claimed by the Cubs in the winter.

Between the Jays and the Cubs, Kay has thrown 82 innings scattered over the past five major league seasons. He has an earned run average of 5.60 in that time, along with a 22.3% strikeout rate, 12.1% walk rate and 42.2% ground ball rate. He’s generally fared better in the minors, which continues to be the case this year. He has a 4.10 ERA in 37 1/3 Triple-A innings, striking out 31.1% of hitters and keeping the ball on the ground at a 52.4% rate. Those numbers are both strong, though his 13.7% walk rate is still concerning.

Kay will be out of options next year, but the Mets can keep him as a depth arm for now. If he manages to hang onto his roster spot through the winter, he can still be retained for five more seasons after this one.

Cubs Designate Anthony Kay For Assignment

By Darragh McDonald | September 11, 2023 at 5:40pm CDT

The Cubs have designated left-hander Anthony Kay for assignment, per Meghan Montemurro of the Chicago Tribune. His 40-man roster spot will go to prospect Pete Crow-Armstrong, whose promotion was reported earlier today. Outfielder Alexander Canario was optioned to open an active roster spot.

Kay, 28, has made 13 appearances for the Cubs this season but with an earned run average of 6.35 in that sample. His eight strikeouts were a match for his eight walks, leading to subpar 14.8% rates in both categories. He’s spent more time in Triple-A this year and has had better results there. In 37 1/3 innings, he has a 4.10 ERA, 31.1% strikeout rate and 52.4% ground ball rate, though his 13.7% walk rate is still quite high.

Since the trade deadline has long passed, the Cubs will have to put Kay on waivers in the coming days. They already passed him through unclaimed back in January, before adding him back to the roster in June. That was his first outright, meaning he didn’t have the right to elect free agency at that time. But if he were to pass through unclaimed a second time, he would then have the right to reject another such assignment.

Kay was once a prospect of note, having gone from the Mets to the Blue Jays alongside Simeon Woods Richardson in the 2019 Marcus Stroman trade. He hasn’t been able to put it together yet, with a career ERA of 5.60 in 82 innings. If any club were intrigued by his past prospect stock or his strikeout stuff in the minors this year, the southpaw comes with five years of control, but he will be out of options next year.

Cubs Select Anthony Kay

By Darragh McDonald | June 13, 2023 at 4:55pm CDT

The Cubs have announced to reporters, including Paul Sullivan of the Chicago Tribune, that they have selected the contract of left-hander Anthony Kay. Right-hander Nick Burdi was transferred to the 60-day injured list to open a spot on the 40-man roster while righty Jeremiah Estrada was optioned to open a spot on the active roster. Earlier today, the club also placed lefty Brandon Hughes on the 15-day injured list due to left knee inflammation while recalling infielder Miles Mastrobuoni in a corresponding move, with Jordan Bastian of MLB.com among those to relay those moves.

Kay, 28, came to the Cubs in December when they claimed him off waivers from the Blue Jays. They put him back on waivers about a month later but were able to get him through, keeping him in the organization. He’s spent the year in Triple-A so far, tossing 28 innings over 23 appearances. He has a 4.50 ERA, 27.4% strikeout rate, 12.8% walk rate and 54.4% ground ball rate.

Prior to joining the Cubs, Kay got some big league experience with the Jays. From 2019 to 2022, he got into 28 games and logged 70 2/3 innings with a 5.48 ERA. He struck out a solid 23.5% of opponents and got grounders at a 44.4% rate but walked 11.6% of batters faced.

The Cubs had been operating for a while with Hughes as their only left-handed reliever. Now that this knee inflammation will put him out of action for a while, Kay will get another shot in the big leagues as the team’s lone southpaw in the bullpen. He has one option year remaining and could be sent back to Iowa at some point while still holding onto his spot on the 40-man. He has between one and two years of service time and could be cheaply retained for future seasons if he does indeed hang onto that spot.

As for Burdi, he had his contract selected in the middle of May but then went on the injured list May 24 due to appendicitis. He’ll now be ineligible to return until 60 days from that initial IL placement, or late July.
