Mets Select José Castillo
The Mets announced today that they have selected left-hander José Castillo to the roster. Right-hander Alex Carrillo has been optioned to Triple-A Syracuse in a corresponding active roster move. Righty Max Kranick has been transferred to the 60-day injured list to open a 40-man spot. It was reported a week ago that Kranick will require season-ending elbow surgery.
The Mets have been churning arms through their bullpen for a long time, thanks to a string of injuries, particularly to left-handers. They had planned on having A.J. Minter and Danny Young as their southpaw contingent in the bullpen but both required season-ending surgeries by the middle of May. Since then, they’ve also lost Kranick and Dedniel Núñez to the scalpel.
Castillo, 29, was one of the reinforcements. He was acquired from the Diamondbacks in mid-May, shortly after Minter and Young went down. He spent a little over a month on the roster, tossing 11 1/3 innings, allowing three earned runs despite giving up 16 hits, issuing six walks and hitting four opponents. He struck out 14 batters and got ground balls on 55.9% of balls in play allowed.
The Mets bumped him off the roster at the end of June and then passed him through waivers. He accepted an outright assignment and has since been pitching for Syracuse, allowing one earned run in 5 1/3 innings.
Not too long ago, the Mets activated Brooks Raley from the injured list, as he had recovered from last year’s Tommy John surgery. They acquired Gregory Soto from the Orioles earlier today. Now with Castillo coming back, they will have three lefties whenever Soto reports to the team. However, it’s also possible that Castillo gets bumped out again to make room for Soto at that point. The Mets could also make further relief additions between now and next week’s deadline.

Mets Designate Zach Pop For Assignment
The Mets announced a series of roster moves today. Outfielder/designated hitter Jesse Winker has been reinstated from the 60-day injured list. He takes the active roster spot of outfielder Starling Marte, who has been placed on the 10-day injured list due to a right knee bruise, retroactive to July 7th. Right-hander Tylor Megill was transferred to the 60-day IL to open a 40-man spot for Winker. The Mets also selected the contract of right-hander Alex Carrillo, a move which was reported earlier. Righty Zach Pop has been designated for assignment as a corresponding move there. The Mets also announced that they have signed right-hander Junior Fernández to a minor league deal.
Winker, now 31, had a solid bounceback season with the Mets in 2024. After a down year in 2023, he put up a .253/.360/.405 slash and 118 wRC+ with the Mets last year. That prompted the club to re-sign him via a one-year deal with a $7.5MM guarantee. This year, he got into 24 games and hit .239/.321/.418 before an oblique strain sent him to the IL. He missed a little over two months but can now return to the club’s corner outfield and designated hitter mix.
Subbing out of that mix is Marte. It’s not known how serious this current injury is but he also spent almost a month on the IL last year due to a right knee bone bruise. He is hitting .270/.353/.387 for a 116 wRC+ this year. The Mets have Juan Soto, Brandon Nimmo and Tyrone Taylor in the outfield most nights. Marte has mostly been in the DH spot, but now Winker will take up that role. They hit from opposite sides of the plate, with Marte being a righty and Winker a lefty, so that may impact the club’s deployment when factoring in the opposing pitcher.
Megill landed on the 15-day injured list on June 15th due to a right elbow sprain. His 60-day count is retroactive to that initial IL placement, so he will be eligible for reinstatement in mid-August. He recently started throwing again but it seems the Mets don’t expect him to be able to return within the next month.
The club has been hit hard by the injury bug in recent weeks, with Megill just one of the victims. The situation has led to the Mets frequently cycling pitchers through the roster as they attempt to paper over the large number of absences. Pop was one pitcher who was run through the machine, getting added to the roster just three days ago. He pitched an inning and a third for the Mets on Sunday, allowing three earned runs on five hits without striking anyone out.
He now has 162 1/3 innings of major league work under his belt. He has occasionally shown glimpses of being an effective ground ball guy. 55% of the balls in play he’s allowed have been pounded into the ground and his 7.8% walk rate is also decent but he has only struck out 17.8% of batters faced. He has a 4.88 ERA overall, which isn’t terrible, but his best work is a few years old now. He has a 6.68 ERA dating back to the start of the 2023 season, in 68 2/3 innings.
He is now out of options, which has limited his ability to cling to a roster spot. But he’s cheap, as the Blue Jays are on the hook for the majority of his $900K salary since they released him earlier this year. Other clubs can sign him and only pay him the prorated portion of the league minimum for the time spent on the roster. He also got a brief stint with the Mariners before joining the Mets. He has the right to reject outright assignments and will likely end up back on the open market in the coming days.
Fernández, 28, signed a minor league deal with the Royals in the offseason but was released a few days ago. He had logged 38 1/3 Triple-A innings in the Royals’ system with a 4.93 ERA, 30.3% strikeout rate and 50% ground ball rate but a concerning 14.9% walk rate.
His big league career has had a somewhat similar shape. He has 54 big league innings under his belt with the Cardinals and Pirates, with a 5.17 ERA, 18.7% strikeout rate, 13.9% walk rate and 49.4% ground ball rate. As mentioned, the Mets have been hit hard by injuries, so there’s little harm in adding some non-roster depth.

Mets To Select Alex Carrillo
The Mets are selecting the contract of hard-throwing righty Alex Carrillo, as first reported by Anthony DiComo of MLB.com. He’s not on the 40-man roster, so they’ll need to make multiple transactions to facilitate the 28-year-old’s first call to the majors.
Carrillo’s journey to the majors is fairly remarkable. The California native went undrafted out of Alabama’s Faulkner University in 2019 and briefly signed with the Rangers that summer. He pitched 4 1/3 innings with their Rookie-level affiliate in the Arizona Complex League but, like many low-level minor leaguers, was cut loose the following year as teams released large swaths of young talent in the early stages of the pandemic.
Up until Opening Day 2025, those 4 1/3 innings in the Rangers system was Carrillo’s only experience in affiliated ball. He’s since pitched for two different teams in the independent Frontier League and has also pitched in two seasons for los Tigers de Quintana Roo in the Mexican League. The Mets scouted him this past winter when he was pitching for los Tigres de Aragua in the Venezuelan Winter League, and Carrillo impressed enough to land a minor league contract.
Carrillo was not invited to major league spring training and was assigned to Double-A to begin his Mets tenure. He’s proven to be a terrific under-the-radar pickup thus far. The 6’2″, 220-pound righty posted a 4.19 ERA in 19 1/3 Double-A frames but did so with an eye-catching 36.6% strikeout rate. That 4.19 earned run average also included a rocky start that was followed by a huge finish; Carrillo pitched 14 1/3 innings with a 1.88 ERA and a 24-to-3 K/BB ratio before being promoted to Triple-A. He’s responded with another 5 2/3 innings of nearly perfect pitching in Syracuse. Carrillo hasn’t allowed a hit or a walk there but did plunk one batter. He’s fanned ten opponents and averaged 98.5 mph on his heater.
Setting aside Carrillo’s first four appearances with the Mets — he allowed six runs in five innings during that initial stretch — he’s riding a 20-inning streak of 1.35 ERA ball with just three runs on nine hits and three walks. He’s punched out 34 batters in that time and has shown the ability to reach triple digits with his four-seamer.
Since this is Carrillo’s first call to the majors, he’ll have a full slate of minor league options. The Mets will be able to shuttle him up and down between Syracuse and Queens for the remainder of this season and two subsequent seasons. He’ll have the standard six full seasons of club control, meaning that if he can continue to shatter expectations, he can be controlled all the way through 2031.
