White Sox Sign Dan Altavilla To Major League Deal

By | at

Just two days after opting out of his minor league deal with the White Sox, righty Dan Altavilla is back with the club — this time on the big league roster. The Sox announced Friday that they’ve signed Altavilla to a major league contract that’ll pay the MAS+ client a prorated $1MM base salary. Fellow righty Miguel Castro has been placed on the 15-day injured list to open a spot on the active roster. Castro suffered a season-ending knee injury while covering first base on a grounder earlier this week, which the Sox have now confirmed as a torn patellar tendon. Chicago already had a 40-man roster vacancy, and Altavilla’s signing now brings them to capacity.

At the time Altavilla was granted his release, it seemed odd that the Sox had passed on giving him a look in the majors. He’s tallied 21 2/3 innings with a strong 2.49 ERA with Triple-A Charlotte this season and had just rattled off a run of 11 2/3 shutout frames. The righty’s 19.8% strikeout rate and 11% walk rate were both worse than average, but he’s averaged 96.1 mph on his heater and held opponents to an awful 24.6% hard-hit rate. Considering the general state of the rebuilding White Sox’ big league bullpen, he seemed like a natural candidate to get an opportunity.

Whether this was always the plan or was borne out of Castro’s unfortunate injury, Altavilla will now get that chance in the majors. This will be his eighth season logging time in the big leagues. He’s previously suited up for the Mariners, Padres and Royals, combining for 119 2/3 innings of 4.36 ERA ball.

Altavilla did his best work early in his career with the Mariners. From 2016-18, he pitched to a tidy 3.28 earned run average with a 25.3% strikeout rate and 10.7% walk rate over 79 2/3 frames. Persistent injuries have limited his time on the field, however. He’s managed only 40 total big league innings since that early run with Seattle.

Flexor strains in both 2018 and 2019 shortened two of Altavilla’s seasons with the Mariners. He struggled to a 5.52 ERA in the latter campaign and in 2020 was included alongside Austin Nola and Austin Adams in the lopsided trade that sent Andres Munoz, Ty France, Luis Torrens and Taylor Trammell from San Diego to Seattle. Altavilla then underwent Tommy John surgery in 2021, which wiped out nearly all of his 2021-22 seasons.

With the White Sox, there should be plenty of innings available over the final four months. The Sox would be thrilled if Altavilla could approach his minor league run-prevention levels in the majors, but even if he can simply replicate his career norms, it’d be a help for a bullpen that’s pitched to a 4.53 ERA on the season — ninth-highest in MLB. Even that pedestrian number is a bit misleading, however, as it includes two “relief” appearances from starter Jonathan Cannon, who followed an opener on those days. Cannon pitched 13 2/3 innings with a 1.98 ERA in those two outings. Subtracting that from the equation, White Sox relievers have a 4.70 ERA on the year.

White Sox Release Dan Altavilla

By | at

The White Sox have released right-handed reliever Dan Altavilla, per the transaction log at MiLB.com. He’d been on a minor league deal and pitching with their Triple-A affiliate in Charlotte.

Altavilla, 32, boasts a sharp 2.49 ERA in 21 2/3 frames with the Knights this season, including a recent run of 11 2/3 shutout innings. He’s fanned only 19.8% of his opponents against a bloated 11% walk rate, but it’s been a nice run of run-prevention for the journeyman righty, who’s averaging a hearty 96.1 mph on his four-seamer in Charlotte while yielding a lowly 24.6% hard-hit rate.

A veteran of seven major league seasons, Altavilla did his best work early in his career with the Mariners. From 2016-18, he pitched to a tidy 3.28 earned run average with a 25.3% strikeout rate and 10.7% walk rate over 79 2/3 frames. Persistent injuries have limited Altavilla’s time on the field, however. He’s managed only 40 total big league innings since that early run with Seattle.

Flexor strains in both 2018 and 2019 shortened two of Altavilla’s seasons with the Mariners. He struggled to a 5.52 ERA in the latter campaign and in 2020 was included alongside Austin Nola and Austin Adams in the lopsided trade that sent Andres Munoz, Ty France, Luis Torrens and Taylor Trammell from San Diego to Seattle. Altavilla then underwent Tommy John surgery in 2021, which wiped out nearly all of his 2021-22 seasons.

Altavilla made a brief big league return with the 2024 Royals, tossing 3 2/3 innings for Kansas City. He was tagged for six runs in that short look and subsequently designated for assignment. The former fifth-round pick spent the rest of the 2024 season with the Royals’ top minor league affiliate in Omaha, where he logged 41 innings with a 3.51 ERA, a league-average 22.2% strikeout rate and a heavy 12.9% walk rate. The rate stats were shaky, but the combined 44 2/3 frames between Triple-A and the majors were the most Altavilla had pitched in a season since 2019.

There’s no indication that Altavilla is dealing with any kind of injury in 2025. He pitched for the Knights just a few days prior to his release and tossed a scoreless inning. As was the case in 2024, Altavilla’s rate stats are a bit wobbly, but he’s throwing hard, limiting hard contact and keeping runs off the board. That should earn him a new opportunity before long.

White Sox Re-Sign Dan Altavilla To Minor League Deal

By | at

The White Sox re-signed right-hander Dan Altavilla over the weekend, as reflected in his transactions tracker at MLB.com. The righty pitched an inning and two thirds for Triple-A Charlotte yesterday.

Altavilla, 32, signed a minor league deal with the Sox in the winter. He tossed 9 2/3 innings for them during the spring, allowing three earned while striking out 11 opponents, issuing four walks and hitting two batters. He didn’t break camp with the club and opted out of that deal but has now circled back to the Sox on a fresh contract.

The righty has some capable big league work on his track record, though it’s been a few years since he complied the bulk of it. From 2016 through 2020, he tossed 114 2/3 innings for the Mariners and Padres. He had an ERA of exactly 4.00 in that time, with a strong 26% strikeout rate but also a high walk rate of 12.3%.

But he has thrown only five big league innings since then. Tommy John surgery in the summer of 2021 wiped out most of that year and the subsequent season. In 2023, he was with the Red Sox on a minor league deal but his results weren’t strong and he didn’t get a call-up. He made it back to the show with the Royals last year but landed on the injured list with a right oblique strain after just five appearances. When he was healthy, he was bumped off the roster as opposed to being reinstated.

The Sox have a pretty inexperienced bullpen. Mike Clevinger is the only reliever on the active roster with more than five years of service time. He has spent most of his career as a starter and is only now making the move to full-time relief. Swingman Bryse Wilson is the only other guy with at least four years of service while only Penn Murfee is also over the one-year line.

It’s understandable why a rebuilding club like the Sox would want to try out young arms to see what happens but some of them will surely struggle or simply get hurt. In short, there should be opportunities available for Altavilla throughout the year if he can stay healthy and somewhat effective.

Dan Altavilla Opts Out Of White Sox Deal

By | at

Dan Altavilla exercised an out clause in his minor league deal with the White Sox, reports Jon Heyman of The New York Post. The right-hander was granted his release and is again a free agent.

Chicago gave Altavilla a non-roster invite to big league camp in December. He had a solid Spring Training, working 9 2/3 innings of three-run ball with 11 strikeouts. The White Sox nevertheless opted not to carry him on the big league roster, sending him back to the open market.

Altavilla made five appearances for the Royals last season. He gave up six runs across 3 2/3 frames before sustaining an oblique strain that knocked him out of action for two months. Kansas City waived him rather than reinstate him onto the MLB roster once he was healthy. That was Altavilla’s first major league work since he made two appearances for the Padres in 2021.

The 32-year-old spent most of last season with K.C.’s Triple-A club. He turned in a 3.51 ERA with a 22.2% strikeout rate and a 12.9% walk percentage across 41 innings. The Triple-A and Spring Training numbers should land him a minor league deal somewhere.

White Sox Sign Dan Altavilla To Minor League Deal

By | at

The White Sox announced Thursday that they’ve signed right-handed reliever Dan Altavilla to a minor league contract. The MAS+ Agency client will be in spring training as a non-roster invitee.

Altavilla, 32, has pitched in parts of seven big league seasons but frequently dealt with injuries that have limited his amount of time on the mound. Since making his MLB debut with the 2016 Mariners, Altavilla’s laundry list of injuries includes shoulder inflammation, a pair of UCL sprains (the latter resulting in Tommy John surgery), a forearm strain and a notable oblique strain that sent him to the 60-day injured list just this past season.

In his first three seasons from 2016-18, all coming with Seattle, Altavilla pitched a combined 79 2/3 innings with a 3.28 ERA, 25.3% strikeout rate and 10.7% walk rate. He’s managed just 40 big league innings since, working to a combined 6.53 earned run average along the way. It’s not as though Altavilla has been consistently healthy in the minors during that stretch, either; he’s totaled 84 1/3 minor league frames in that time, bringing him to a total 120 1/3 frames in a span of six years.

There’s little doubt that Altavilla is talented when his arm is right. Even with his recent injury-plagued seasons weighing down his career numbers, he carries a 4.36 ERA and 26% strikeout rate in the big leagues. He pitched just 3 2/3 MLB innings with Kansas City this past season but averaged a sizzling 96.8 mph on his heater. In 41 Triple-A innings for K.C., he logged a 3.51 ERA, albeit with a 22.2% strikeout rate and 12.9% walk rate — both pedestrian marks.

The rebuilding White Sox will have plenty of room for non-roster players to compete for bullpen jobs this coming spring. Right now, the only relievers with even a year of experience in the Chicago bullpen are Justin Anderson, Jared Shuster, Steven Wilson and Ron Marinaccio. If Altavilla cracks the roster, he could log some meaningful innings and will be controllable through the 2026 campaign, as he currently has only 4.153 years of MLB service.

11 Players Elect Free Agency

By | at

As the offseason nears, a number of players elect minor league free agency each week. These players are separate from six-year MLB free agents, who’ll reach the open market five days after the conclusion of the World Series. Eligible minor leaguers can begin electing free agency as soon as the regular season wraps up. These players were all outrighted off a team’s 40-man roster during the year and have the requisite service time and/or multiple career outrights necessary to reach free agency since they weren’t added back to teams’ rosters.

Electing free agency is the anticipated outcome for these players. There’ll surely be more to test the market in the coming weeks. We’ll offer periodic updates at MLBTR. These transactions are all reflected on the MiLB.com log.

Royals Outright Dan Altavilla

By | at

The Royals announced this afternoon that right-hander Dan Altavilla has cleared waivers and been assigned outright to Triple-A Omaha. The right-hander was designated for assignment by Kansas City earlier this week when they activated him from the 60-day injured list but did not add him back to the 40-man roster.

Altavilla, 31, was a fifth-round pick by the Mariners back in 2014 who made his big league debut in Seattle during the 2016 season. He provided solid middle relief for the club in the first few years of his career with a combined 3.28 ERA and 4.32 FIP in 79 2/3 innings of work from 2016 to 2018, but struggled badly over the next three seasons with the Mariners and Padres. In 36 1/3 innings of work across 41 games between 2019 and 2021, Altavilla posted a 5.70 ERA with a 4.55 FIP before undergoing Tommy John surgery in June of the 2021 season.

The right-hander’s time with the Padres came to a close shortly after he went under the knife, and though he signed a two-year minor league deal with the Red Sox prior to the 2022 season he never made it into a big league game in Boston. He made his return in the minors with the Red Sox, however, with a 3.00 ERA but a lackluster 14.3% strikeout rate in eight appearances that spanned 12 innings in total before he was released by the club in August of that year. He didn’t catch on with another club down the stretch in 2023 but found a minors pact with the Royals back in December.

In Kansas City, Altavilla found his first big league opportunity since 2021 when the club selected his contract back in June. Unfortunately, the righty made just five appearances that saw him surrender six runs in just 3 2/3 innings of work before he found himself back on the injured list due to an oblique strain. He began a rehab assignment early last month but struggled at the Triple-A level during that time with a ghastly 9.39 ERA in eight appearances. That led the Royals to designate the righty for assignment once he had reached the maximum rehab time in the minor leagues, though he evidently went unclaimed on waivers and now will return to Omaha with the Royals as a non-roster depth option for the club down the stretch.

While the Royals have struggled to get consistent results from their bullpen this year with a relief corps that’s bottom five in the majors by ERA since the calendar flipped to August and bottom six overall this season, it nonetheless seems unlikely that the club would turn to Altavilla down the stretch barring injuries forcing the clubs’ hand. Lucas Erceg, John Schreiber, and James McArthur form a solid enough back-end trio for the club with strong peripherals despite mediocre results, and the trio of Kris Bubic, Sam Long, and Carlos Hernandez have performed well in the middle innings of late to leave few reasons for the club to make a change as they enter the stretch run in position to make the postseason for the first time since their 2015 World Series championship.

Royals Designate Dan Altavilla For Assignment

By | at

The Royals announced that right-hander Dan Altavilla has been designated for assignment. He had been on the 60-day injured list and was on a rehab assignment but it seems they didn’t want him to retake a spot on their 40-man roster, so he’s now in DFA limbo instead.

Altavilla, 31, signed a minor league deal with the Royals in the offseason and was selected to their roster in June. He made five appearances for the club, allowing six earned runs in 3 2/3 innings via five hits, three walks and breaking Mookie Betts’ hand.

The righty then landed on the 15-day injured list due to a right oblique strain, later getting transferred to the 60-day IL. He started a rehab August 6 and was coming up to the end of his 30-day maximum rehab window. Since he’s out of options, the club was going to have to add him back onto both the 40-man and active rosters, but they decided to cut him loose instead.

Since it is the post-deadline part of the schedule, Altavilla will be placed on waivers in the coming days. If he were to pass through unclaimed, he would have the right to elect free agency, both due to having a previous career outright and at least three years of service time.

His recent major league stint with the Royals adds a small amount of data to his career stats. He now has 119 2/3 innings pitched with a 4.36 ERA in seven different seasons. His 26% strikeout rate is quite strong but his 12.2% walk rate is definitely on the high side. Most of that came from 2016 to 2021 as he didn’t pitch in the majors in either 2022 or 2023, missing most of that time due to Tommy John surgery.

Royals Select Walter Pennington

By | at

The Royals announced today that they have reinstated infielder/outfielder Adam Frazier from the injured list and selected the contract of left-hander Walter Pennington. In corresponding moves, they optioned infielder CJ Alexander and right-hander Carlos Hernández. To open a 40-man spot for Pennington, right-hander Dan Altavilla was transferred to the 60-day injured list.

Pennington, 26, signed with the Royals as an undrafted free agent in 2020. That year’s draft was reduced to just five rounds due to the pandemic. Since then, he has been climbing the minor league ladder, getting lots of strikeouts and ground balls but also struggling with command at times.

Last year, he tossed 70 2/3 innings between Double-A and Triple-A, allowing 3.18 earned runs per nine frames. He struck out 25.5% of batters faced and got grounders on more than half of the balls allowed in play, but he also gave out walks at an 11.9% clip. Here in 2024, he’s tossed 53 2/3 innings over 32 Triple-A appearances. He has a huge 35.3% strikeout rate and 52.6% ground ball rate, also reducing his walk rate to 8.8%.

That strong performance will get him called up to the big leagues for the first time. He’ll provide the Royals with a left-handed reliever, one capable of pitching multiple innings per outing. 14 of his 32 appearances this year have been for two innings or longer, with Pennington getting as high as four frames.

As for Altavilla, he landed on the 15-day IL on June 2o due to a right oblique strain. He’ll now be ineligible to return until 60 days from that initial IL placement, which would be the middle of August.

Royals Select Dan Altavilla

By | at

The Royals announced that they have selected the contract of right-hander Dan Altavilla. The club already had a 40-man vacancy. Right-hander Will Klein was optioned to open an active roster spot.

Altavilla, 31, signed a minor league deal with the Royals in the offseason. He has since made 24 appearances for Triple-A Omaha, allowing 2.63 earned runs per nine innings. That’s at least partially luck, as he has been giving out walks at a 12.8% clip and can’t continue stranding 91.8% of baserunners forever. But his 27.5% strikeout rate with the Storm Chasers was quite strong and he’s also been getting grounders on 44.6% of balls in play.

That performance will get Altavilla back to the big leagues for the first time since 2021. He made 119 appearances in the majors from 2016 to 2021 with a 4.03 ERA, 26.1% strikeout rate, 12.1% walk rate and 38.8% ground ball rate. But he underwent Tommy John surgery in June of 2021 and hasn’t made it back to the majors until now.

He signed a two-year minor league deal with the Red Sox and didn’t pitch in any official capacity in 2022. He returned to the mound last year but struggled to get back in form right away. He tossed 12 innings on the farm last year with an ERA of 3.00, but he was helped by a tiny .194 batting average on balls in play as he only struck out 14.3% of opponents while giving out walks at a 10.2% clip.

The Sox released him in August but his new deal with the Royals seems to have allowed him to get back on track. It was reported last week that the Royals are looking for bullpen help, with some more swing-and-miss a specific target area. Altavilla could perhaps give the club an internal source of that upgrade they are looking for, based on his strikeout numbers this year and earlier in his career.

If Altavilla clicks, perhaps that will alter the club’s approach prior to the July 30 trade deadline. If it doesn’t work out, he’s likely to end up designated for assignment since he is out of options. But if he manages to hang onto his roster spot through the end of the schedule, he can be retained for next year via arbitration since he has less than five years of major league service time.
