Giants finalize trade for Marcelo Mayer

Marcelo Mayer

SF 2nd Baseman #11

Player Stats

Giants acquired INF Marcelo Mayer from the Red Sox for LHP Erik Miller and OF Carlos Gutierrez.

Mayer was viewed as one of Boston’s potential future franchise cornerstones just a few years previously. He simply never found his footing at the highest level despite possessing impressive raw talent and a sweet-looking left-handed swing. The 23-year-old former fourth overall selection from the 2021 draft has struggled to stay healthy at the highest level and the Red Sox ultimately decided to move on, using him as a trade chip to fortify their bullpen. The meteoric rise of Franklin Arias, who has emerged as the club’s potential shortstop of the future, seemingly sealed Mayer’s fate here. It’s a decent move for his long-term future as he’ll get a change of scenery and plenty of opportunities to emerge as a key contributor in San Francisco.

Osleivis Basabe (hamstring) remains out of action for Sunday’s season finale against the Dodgers.

Basabe has been shelved since Monday due to tightness in his left hamstring. It’s possible that he could be available off the bench on Sunday. Marcelo Mayer will start at the hot corner for the Giants and will bat cleanup against Jack Dreyer and a host of Dodgers’ relievers.
Marcelo Mayer

SF 2nd Baseman

Giants activated INF Marcelo Mayer from the 10-day injured list.

Mayer will make his San Francisco debut during Monday’s series opener against the Twins at Oracle Park. The 23-year-old former top prospect, who came over from the Red Sox in the Erik Miller swap at the trade deadline last month, has been out nursing forearm and foot injuries since late June. He’s talented enough to be an impactful fantasy contributor at some point in the future, but it simply hasn’t happened at this early juncture of his career. He could benefit exponentially from the change of scenery, but is unlikely to offer much in the final week of the regular season.
Willy Adames

SF Shortstop #2

Willy Adames has been diagnosed with a moderate UCL sprain in his left elbow.

It doesn’t sound like Adames will require surgery to address the issue, but he’s headed for a second opinion before that decision is made. It certainly seems like his season is over. The 30-year-old hit the shelf with an elbow sprain earlier this week. It’ll most likely be Christian Koss filling in at shortstop until trade deadline acquisition Marcelo Mayer is ready to return from the injured list.
Marcelo Mayer

SF 2nd Baseman

Giants’ manager Tony Vitello told reporters on Friday that Marcelo Mayer is dealing with a bone bruise on his right foot.

It’s an injury that also bothered him while Mayer was doing his rehab at Triple-A Sacramento and isn’t expected to keep him shelved for long. He’ll rest for the remainder of the weekend before being evaluated when the Giants return home next week.
Marcelo Mayer

SF 2nd Baseman

Marcelo Mayer went 1-for-6 with four strikeouts as Triple-A Sacramento’s leadoff man on Sunday.

Mayer, out since late June with a stress reaction in his forearm, is 5-for-14 with a homer in three games since joining the River Cats. They might wait a few more days, but the Giants will likely activate him this week and install him as their starting second baseman.
Marcelo Mayer

BOS 2nd Baseman #11

The Red Sox are trading Marcelo Mayer to the Giants for Erik Miller, sources told The Athletic.

The Red Sox sure are burning a lot of talent here. Miller is quite good and under control for three years after this one, but giving up a long-term regular for a left-handed reliever is quite a loss of value. Mayer is currently on the shelf with an arm injury and might not be much of a factor this year, but he should be the Giants’ second baseman next year and he remains very much an option at short if the club could find a taker for Willy Adames. Miller’s fantasy value disappears with the deal, since he won’t be a candidate for saves in Boston. With the Giants shedding both he and Caleb Kilian, Dylan Smith is probably their favorite for saves at the moment.
Marcelo Mayer

BOS 2nd Baseman #11

Marcelo Mayer (forearm) has been cleared to start a hitting progression.

Mayer landed on the injured list with a stress reaction in his left forearm. He was allegedly playing through the injury for two months, which may have impacted his performance on the field. It may just be a couple of weeks before Mayer could begin a rehab assignment, but his role in Boston for the remainder of the season remains to be seen. The team has been thriving, and they have multiple options in the infield with Romy Gonzalez back and Anthony Seigler and Tsung-Che Cheng providing value. The Red Sox could opt to keep Mayer in Triple-A to get consistent at-bats until rosters expand in September.
Marcelo Mayer

BOS 2nd Baseman #11

Red Sox placed INF Marcelo Mayer on the 10-day injured list with a bone stress reaction to his left ulna.

Mayer has been battling the forearm issue for the past two months according to interim manager Chad Tracy and it finally got to the point where they had to shut him down. No word yet on how long he’ll be sidelined for, but they’ll take it “week to week”. Tsung-Che Cheng was recalled from Triple-A Worcester to take his place on the club’s active roster.
Marcelo Mayer

BOS 2nd Baseman #11

Marcelo Mayer (illness) was a late addition to the Red Sox’ lineup for Friday’s game against the Mariners.

Mayer sat out on Thursday due to illness and wasn’t feeling well during the day on Friday, but he felt much better as game time approached and seemingly was able to talk his way into the lineup. He’ll start at shortstop and bat seventh with Isiah Kiner-Falefa heading back to the bench.
Marcelo Mayer

BOS 2nd Baseman #11

Marcelo Mayer was held out of the Red Sox’ lineup for the second straight game on Friday night due to illness.

It doesn’t sound like Mayer is going to require a trip to the injured list, but he’s still feeling a bit under the weather on Friday. Andruw Monasterio will start at second base and bat ninth for the Red Sox while Isiah Kiner-Falefa slides over to cover shortstop once again.

Rays manager Kevin Cash said after Tuesday’s game that Junior Caminero was fine after exiting for a pinch-runner in the 12th.

He didn’t seem fine, and Caminero himself indicated that there was a foot issue, though he was adamant that he’d play Wednesday. Caminero came up lame while trying to beat out a grounder on Joey Ortiz’s error in the 12th and stayed in to run to third on a single before being replaced by Cedric Mullins.

Jonny DeLuca hit a game-tying single in the 12th inning to help the Rays to a win over the Brewers in Game 4 of the World Series on Tuesday.

DeLuca took advantage of a drawn-in infield with runners on first-and-third and singled up the middle to tie the game at 3-3. It was his only hit of the game and he has scuffled mightily over this postseason, but he keeps the Rays alive with a chance to make the series a little tighter with a Game 5 win Wednesday.

Cooper Pratt went 4-for-5 with a go-ahead homer in the 12th inning in a Game 4 loss to the Rays on Tuesday.

Pratt also singled twice and doubled, but the hit he will remember forever was his go-ahead homer off Ian Seymour that gives the Brew Crew a 3-2 lead in the 12th. Unfortunately for Pratt and the Brew Crew, it wasn’t enough with Tampa Bay scoring twice in the bottom of the frame. The 22-year-old has been outstanding in the postseason minus some mental gaffes, but the Brewers will need to win one more game to clinch that first championship.

Ben Williamson hit a walk-off single in the 12th inning to give the Rays a 4-3 win over the Brewers in Game 4 of the World Series on Tuesday.

Yep, just like we all predicted. With the bases loaded, Williamson took a defensive hack that scooted through the turf of Tampa Bay to give the Rays a win and staved off elimination for at least one more game. The 25-year-old has his first-ever postseason RBI, and likely won’t be in the lineup in Game 5 come Wednesday. He’ll be able to stay he had a game-winning hit in the World Series, however, which has to feel pretty dang good.

Griffin Jax

TB Starting Pitcher #22

Griffin Jax allowed two runs while working four innings Tuesday in a Game 4 start against the Brewers on Tuesday.

Jax gave up a ton of loud contact with nine balls in play registering as hard hits. He also generated 11 swings and misses and six strikeouts, so it was more of a case of poor command than lack of stuff. He also was almost assuredly left in too long, and gave up a homer to David Hamilton in the fifth before exiting. Jax did a solid job as a starter for Tampa Bay in 2026, and he’ll likely be back in the middle of the Rays’ rotation in 2027, but he likely will be an option in Game 6 or 7 if Tampa Bay can force one.

Dustin May gave up two runs in three innings while not factoring in the decision against the Rays on Tuesday in Game 4 of the World Series.

May pounded the strike zone, and threw 30-of-39 pitches for strikes without issuing a walk. He found too much of the plate a time or two too many, however, and gave up an RBI double to Chandler Simpson and was charged for another run in the fourth after exiting with zero outs. May has a $20 million option that will assuredly be declined, so he’ll be a free agent who should have a decent market this winter. He could also pitch at some point out of the bullpen over the next few games, if necessary.

Dustin May will start Game 4 of the World Series, the Brewers confirmed.

It sounds like Brandon Woodruff would have opened tonight if he hadn’t finished last night’s game. As is, May will make his second start of the postseason after pitching in relief his last three times out. He’s surrendered five runs in eight innings thus far in October. The Brewers figure to be very aggressive tonight with all of their key relievers having enjoyed back-to-back days off.

The Rays have Jonathan Aranda back at first base but are starting Ryan Vilade over Victor Mesa Jr. in right field in Tuesday’s Game 4 against the Brewers.

Vilade started over Aranda at first base against a lefty on Monday. That Mesa committed a miscue in that one might factor into him taking a seat tonight, but on paper, going to Vilade against a righty seems like a bit of a downgrade both offensively and defensively. The Rays’ lineup as they try to extend the series: DH Yandy Díaz, 1B Aranda, 3B Junior Caminero, C Liam Hicks, CF Jonny DeLuca, LF Chandler Simpson, RF Vilade, 2B Richie Palacio and SS Taylor Walls.

Sal Frelick has been moved up to sixth, swapping spots with Garrett Mitchell, in the Brewers’ Game 4 lineup on Tuesday.

It’s the first change of the World Series for the Brewers, but they’re going with the same nine while facing a fourth straight righty. Frelick moves up despite taking a hard fall on his troublesome right shoulder late last night. He’s 4-for-11 with a homer through three games, compared to 2-for-11 for Mitchell. The lineup: LF Jackson Chourio, 1B Jake Bauers, DH Christian Yelich, C William Contreras, 2B Brice Turang, RF Frelick, SS Cooper Pratt, CF Mitchell and 3B David Hamilton.

Joe Espada and Jason Kanzler are the two finalists for the Mariners’ managerial job, according to Adam Jude of the Seattle Times.

Rocco Baldelli might have been the favorite for the gig before withdrawing from consideration. Now it’s down to Espada, who spent the last three years managing the Astros, and Kanzler, the Cubs’ farm director who would be managing for the first time. A decision should come before the end of the week.
