Astros, Jack Winkler Agree To Minor League Contract
The Astros are in agreement with infielder Jack Winkler on a minor league contract, according to the MLB.com transaction log. The 27-year-old elected minor league free agency after being outrighted by the Marlins at the end of last season. He’s represented by the Ball Players Agency.
Winkler was a 10th-round draftee by the Athletics in 2021. The University of San Francisco product played four seasons in the A’s system, peaking in Double-A. Miami grabbed him in the Triple-A phase of last offseason’s Rule 5 draft. Winkler got a few looks as the final player on Clayton McCullough’s bench over the course of the season.
He appeared in 14 games, starting four of them in the middle infield. Winkler went 4-16 with a stolen base and committed two errors in 44 1/3 innings of defensive work. He otherwise spent the season at Triple-A Jacksonville, where he hit .225/.299/.333 with a 28% strikeout rate in his first action at the level. Winkler was an asset on the bases in the minors, stealing 25 bags in 76 games without getting thrown out. He played mostly third base in Triple-A with sporadic action up the middle.
Houston is likely to start Winkler back in Triple-A as a right-handed infield depth piece. He has been a below-average hitter throughout his minor league career, so it’s unlikely he’ll be in the running for an Opening Day roster spot even if the Astros trade an infielder during Spring Training. Winkler has options remaining and can bounce between Houston and Triple-A Sugar Land if he earns a 40-man roster spot at any point.

Marlins Claim Zach Brzykcy
The Marlins have claimed right-hander Zach Brzykcy off waivers from the Nationals, per a club announcement. Miami also passed right-hander Christian Roa and infielder Jack Winkler through waivers. Both were assigned outright to Triple-A Jacksonville. Additionally, the Fish reinstated lefties Braxton Garrett and Andrew Nardi and righties Anthony Bender and Max Meyer from the 60-day injured list.
Washington signed the now-26-year-old Brzykcy (pronounced brick-see) as an undrafted free agent following the truncated 2020 amateur draft. He’s seen fairly brief action in each of the past two big league seasons, allowing 32 runs in just 28 2/3 innings of relief.
Brzykcy posted strong minor league numbers in 2022 and 2024 but missed the 2023 season due to Tommy John surgery. His 2025 results with Rochester weren’t any better than they were in the majors, but in ’24 he logged 35 1/3 innings with a 2.04 ERA, a 33.1% strikeout rate and a 10.8% walk rate across four levels as he worked his way back from that ligament procedure. Brzykcy still has a minor league option year remaining, and he’ll hope that a change of scenery can get him back to the minor league form he displayed prior to this year’s dismal showing.
Miami claimed Roa, also 26, off waivers from the Reds one year ago. The 2020 second-rounder tossed three scoreless frames in his first taste of MLB action this year and also logged a 2.83 ERA in 60 1/3 Triple-A frames. Roa has poor command but solid results in the upper minors and an average fastball clocking in at 96 mph. He doesn’t have the service time or prior outright needed to elect free agency. The Marlins are surely happy to hang onto a power arm with decent results, even if his command is suspect.
Winkler came to the Fish by way of the 2024 Rule 5 Draft’s minor league phase. The former A’s farmhand also made his debut in ’25, collecting four singles in 16 at-bats. He can play all over the diamond and has decent speed but minimal offensive production. Winkler hit just .225/.299/.333 in 281 plate appearances at the Triple-A level this year, though he also notched a perfect 25-for-25 record in stolen base attempts.
Garrett missed the 2025 season after undergoing UCL surgery in January. He’ll be back in the rotation mix next year, barring any setbacks, though he might not quite be ready for spring training. Nardi missed the 2025 season due to back injuries and is a non-tender candidate. Bender’s season ended in August due to a stress reaction in his right tibia. Assuming he’s healthy next year, he’ll reprise his role as a key late-inning arm for skipper Clayton McCullough. Meyer, the No. 3 overall pick in 2020, underwent season-ending hip surgery in June. It’s the second notable surgery of the promising right-hander’s career. He also missed half the 2022 season and all of 2023 following Tommy John surgery.
Marlins Announce Several Roster Moves
The Marlins have designated right-hander Luarbert Arias for assignment and selected the contract of infielder Jack Winkler from Triple-A Jacksonville, per a club announcement. They’ve also placed third baseman Connor Norby and outfielder Derek Hill on the 10-day injured list — the former due to a quad strain and the latter due to a hamstring strain. Lefty Josh Simpson and infielder Maximo Acosta have been recalled from Triple-A to take that pair of roster spots.
Arias, a 24-year-old righty, made his major league debut with Miami this season but was torched for 13 runs in 10 1/3 innings. He’s posted a 3.93 ERA in 18 1/3 innings in Triple-A but walked nearly twice as many batters (13) as he’s punched out (seven). The Marlins selected Arias, a former minor league Rule 5 pickup out of the Padres organization, back in November to protect him from being nabbed in the major league phase of the most recent Rule 5 draft.
At the time, it wasn’t hard to see why. Arias was coming off a strong year in Jacksonville, having totaled 68 innings with a 3.04 ERA, 25.8% strikeout rate and 9.3% walk rate. He’s taken notable steps back this season and has already been designated for assignment and passed through waivers once this summer. Because of that prior outright, he can reject a minor league assignment in favor of free agency if he once again goes unclaimed.
Winkler’s contract is being selected to the roster for the second time this season. The 26-year-old utilityman went 2-for-12 with a pair of singles in a very brief MLB look earlier this year but has since been designated for assignment and outrighted. He’s back in the majors now despite struggling through a 9-for-58 skid in Triple-A between big league stints. He’ll add a righty bat with some defensive versatility to the Marlins’ bench while Norby is out, but Winkler posted a lackluster .220/.291/.328 batting line in 261 plate appearances during his Triple-A debut this year, so fans shouldn’t expect much in the way of offensive contributions.
It’s the third IL stint of the season for both Norby and Hill. Given the minimal time left on the regular-season calendar, either injury could feasibly be season-ending, but there’s been no definitive word from the club on that front just yet.
Norby, acquired alongside Kyle Stowers in last summer’s Trevor Rogers trade with Baltimore, hasn’t hit nearly as well as hoped this year. The former top prospect has been sidelined by oblique and wrist injuries previously, batting .274/.298/.373 when healthy enough to take the field. Hill, 29, has played strong defense but hit just .213/.275/.331 in 141 plate appearances on the year. He’s previously missed time due to wrist and finger injuries.
Marlins Outright Jack Winkler
Marlins infielder Jack Winkler went unclaimed on waivers and was outrighted to Triple-A Jacksonville, according to the MLB.com transaction tracker. The 26-year-old neither has the service time nor the previous career outright to decline the assignment. He’ll remain with the team after being designated for assignment on Monday when the Fish claimed outfielder Joey Wiemer off waivers.
Winkler made a brief MLB debut earlier in the season. Acquired from the A’s in the minor league phase of last winter’s Rule 5 draft, he cracked the 40-man roster at the end of May. He spent around six weeks in the big leagues over two stints. Winkler didn’t get a ton of playing time as the final player on Clayton McCullough’s bench. He only started four of his 11 appearances and collected two hits and a stolen base in 12 at-bats.
A University of San Francisco product, Winkler has played parts of five minor league seasons. He’s in his first year at Triple-A and batting .241/.304/.379 over 194 plate appearances. Winkler has never hit much but provides versatility as a depth infielder. He’ll remain with Jacksonville in hopes of getting back onto the big league roster.
Marlins Designate Jack Winkler For Assignment
The Marlins announced that infielder Jack Winkler has been designated for assignment. That’s the corresponding 40-man move for their previously reported claim of outfielder Joey Wiemer off waivers. It also opens an active roster spot for outfielder Derek Hill, who has been reinstated from the 10-day injured list.
Winkler, 26, was just added to Miami’s roster at the end of May. Since then, he has been rarely used as a bench player or down in the minors on optional assignment. He has appeared in just 11 major league games and has been sent to the plate just 12 times, mostly getting put into game as a pinch runner. He has two singles and four strikeouts, giving him a career .167/.167/.167 line in that tiny sample of work.
He now heads into DFA limbo. Since the trade deadline has passed, the Marlins will have to put him on waivers in the coming days. If he garners any interest, it would naturally be based on his larger body of work in the minors.
His offense has generally been subpar but he’s been able to steal bases and bounce around the diamond. In 51 Triple-A games this year, he has a .241/.304/.379 batting line and 84 wRC+. He has stolen 17 bases without getting caught and played all four spots on the infield. He has a small amount of experience in the outfield corners in previous seasons as well.
If he were to pass through waivers unclaimed, he would stick with the Marlins as non-roster depth. He doesn’t have three years of big league experience nor a previous career outright, so he wouldn’t have the right to elect free agency.

Marlins To Designate Matt Mervis, Ronny Simón For Assignment
The Marlins are planning to make several roster moves, per Craig Mish of the Miami Herald. It was already reported earlier today that they would be selecting the contract of outfielder Heriberto Hernández. Kevin Barral of Fish on First reports that infielder Jack Winkler will also be selected to the roster. Per Mish, the club is planning to designate infielders Matt Mervis and Ronny Simón for assignment. That would open two 40-man spots for Hernández and Winkler.
Mervis, 27, was acquired from the Cubs in December with the Fish sending Vidal Bruján to Chicago. Mervis got out to a hot start but with some red flags. Through April 23rd, he already had seven home runs but had also struck out in 36.2% of his plate appearances. The feast-or-famine approach has since pushed hard to the famine side. He hasn’t hit a homer since then while still striking out at a 38.5% clip.
Combining this year’s struggles with his time with the Cubs, Mervis now has a .165/.238/.322 line and 34.5% strikeout rate in 261 major league plate appearances. He had tremendous minor league production in 2022 and 2023, slashing .297/.388/.576, but the strikeouts became a big issue last year. He spent most of 2024 in Triple-A and was punched out at a 30% rate at that level.
There’s clearly some pop in the bat but the Marlins ran out of patience. Mervis is only really capable of playing first base, so he needs to hit in order to have any value. Eric Wagaman isn’t doing much better, with a .227/.277/.382 line this year, but it seems he’ll be the regular first baseman now.
The Marlins will now have a week of DFA limbo to figure out what’s next. The waiver process takes 48 hours, so that gives the club five days to see if there’s any trade interest. He does still have an option, so it’s possible some club out there grabs him and sends him to the minors to try to catch lightning in a bottle.
Simón, 25, was was just added to the 40-man roster last month. He had signed a minor league deal with the Marlins in the offseason. He has since received 56 plate appearances and hit .234/.327/.277.
He got an unfortunate moment in the baseball spotlight this week, as recapped by Jason Foster and Christina De Nicola of MLB.com. Simón made several errors and other defensive miscues as the Marlins blew a 6-0 lead to the Padres on Tuesday, eventually losing 8-6. Simón was seen wiping tears from his face amid the ordeal. But later, he received plenty of encouragement from his teammates and even text messages from players on the opposing team such as Manny Machado, Luis Arráez and Fernando Tatis Jr..
But he’ll now have to endure another challenge, as he’s heading to DFA limbo. He was putting up good numbers in the minors earlier this year, which is why he got up to the big leagues in the first place. He had hit .354/.441/.521 in 15 Triple-A games. That was bolstered by an unsustainable .410 batting average on balls in play but he was drawing walks at a 15% clip while only striking out 16.7% of the time.
As recently as July, FanGraphs considered him to be one of the top 20 prospects in the Rays’ system. But he didn’t get called up last year and hit free agency, which led to his deal with the Marlins. He’s a switch-hitter and capable of bouncing around the diamond while stealing 20-35 bases a year. He still has a full slate of options.
Winkler, 26, gets the call to the big leagues for the first time. He’s never really been a top prospect but the Fish nabbed him from the Athletics in the minor league phase of the Rule 5 draft in November. He has gone on to hit .275/.331/.423 at the Triple-A level this year. That’s propped up by a .351 BABIP but Winkler already has 15 steals. He has played all four infield positions in his career as well as the outfield corners.
