SEA 3rd Baseman #21

Player Stats

Mariners designated INF Miles Mastrobuoni for assignment.

The 30-year-old infielder hit just .217 (5-for-23) with no homers and one RBI in 27 plate appearances over eight games with the M’s. He could pique another team’s interest on waivers.

Josh Naylor

SEA 1st Baseman #12

Josh Naylor (wrist) is out of the lineup for the second straight game on Wednesday against the Orioles.

Naylor receives some extra time off to rest and recover as he battles a lingering wrist issue. The 28-year-old slugger also fouled a ball off his shin over the weekend, which didn’t help matters. It’ll be Miles Mastrobuoni taking over at first base in his absence. All indications have been that Naylor will be ready to return to Seattle’s lineup at some point this week.
Miles Mastrobuoni

SEA 3rd Baseman #21

Mariners activated INF/OF Miles Mastrobuoni from the 60-day injured list.

Mastrobuoni returns to Seattle’s bench mix as a versatile multi-position specialist after missing the first 10 weeks of the season recovering from a calf strain that he suffered while playing in the World Baseball Classic.
Miles Mastrobuoni

SEA 3rd Baseman #21

Mariners transferred INF/OF Miles Mastrobuoni to the 60-day injured list.

The procedural move opens up a spot on Seattle’s 40-man roster. Mastrobuoni has been on the shelf since suffering a calf strain while playing in last month’s World Baseball Classic.
Miles Mastrobuoni

SEA 3rd Baseman #21

Mariners placed INF Miles Mastrobuoni on the 10-day injured list with a right calf strain.

Mastrobuoni wasn’t originally in line to make the Mariners, though he might have gotten a spot with J.P. Crawford down. Instead, he’ll join Crawford on the IL. Mastrobuoni hit .250/.324/.298 in 175 plate appearances over 76 games last season.

SEA 3rd Baseman #21

Miles Mastrobuoni is leaving Team Italy after suffering a calf injury during Tuesday’s win over the United States.

No word yet on the severity. However, with Seattle’s season-opener roughly two weeks away it’s possible he’ll require a trip to the injured list. The versatile 30-year-old’s absence could potentially open the door for sizzling-hot former top prospect Brennan Davis to win a spot on the club’s Opening Day roster.
Miles Mastrobuoni

SEA Infield #21

Miles Mastrobuoni hit a grand slam Saturday in a 10-5 Cactus League loss to the Giants.

He also doubled. Mastrobuoni took Hayden Birdsong deep to give the Mariners a 5-0 lead in the first inning. It’d be the last run Seattle would score. Mastrobuoni provided versatility off the bench in 2025, but he’s not a lock to make the roster to open 2026.
Bryan Woo

SEA Starting Pitcher #22

Bryan Woo (pectoral) is on the Mariners’ roster for the ALCS against the Blue Jays.

Woo’s return provides a massive lift for Seattle’s rotation mix for the best-of-seven series against Toronto after missing the ALDS recovering from pectoral inflammation. It’s unclear when he’ll take the ball during the extended series, but Mariners manager Dan Wilson should provide an update at some point prior to Game 1. The 25-year-old ace posted a spectacular 2.94 ERA across a career-high 186 2/3 innings over 30 starts during the regular season. The only other changes for the Mariners involve versatile Miles Mastrobuoni joining their bench mix with Luke Raley and rookie Ben Williamson being left off.

SEA 2nd Baseman #21

Mariners recalled INF/OF Miles Mastrobuoni from Triple-A Tacoma.

Mastrobuoni returns for Sunday’s regular-season finale against the Dodgers after spending most of the final two months back in the minors. The 29-year-old’s defensive versatility gives him some appeal in a bench role during the playoffs.
Miles Mastrobuoni

SEA 2nd Baseman #21

Miles Mastrobuoni will serve as the 27th man for Sunday’s Little League Classic against the Mets.

Mastrobuoni provides Seattle with some additional bench versatility for Sunday’s matchup in Williamsport, Pennsylvania. He’ll likely head back to Triple-A Tacoma at the conclusion of the contest.
Miles Mastrobuoni

SEA 2nd Baseman #21

Mariners optioned INF/OF Miles Mastrobuoni to Triple-A Tacoma.

The versatile 29-year-old is getting the boot with Luke Raley returning from the injured list on Friday. Mastrobuoni has hit .248/.323/.289 with just one homer, 12 RBI and six stolen bases in 172 plate appearances with the Mariners this season.

Red Sox manager Chad Tracy said that Roman Anthony (sprained wrist/hand) “hasn’t made any substantive progress while the Red Sox have been away.”

Anthony has apparently tried to swing a lighter bat, but hasn’t gotten to a real hitting progression. He’s eight weeks into an 8-12 week timeline for his sprained wrist and torn ligament in his ring finger. At this point, with the Red Sox struggling as badly as they are, we’d expect Anthony to take at least the remaining four weeks on that timeline. That puts him back after the All-Star break.

The Athletic’s Will Sammon reports that Francisco Lindor (calf) will return for Game 2 of the doubleheader on Wednesday against the Cubs.

Lindor has been out since late April with a calf strain, so the Mets will love to have him back. The only issue is that Juan Soto may not have to head to the injured list with a back injury. Soto and Lindor have only played nine games together so far this season.

Rockies placed RHP Jaden Hill on the 15-day injured list, retroactive to June 21, with right shoulder tendinitis.

Hill has earned the Rockies’ last two saves, so this is bad timing for him. The 26-year-old has a 5.06 ERA overall in 26 2/3 innings on the season. Antonio Senzatela and Victor Vodnik are better bets for saves while Hill is out, but no one in the Rockies pen seems worth rostering right now.

Rockies recalled RHP Seth Halvorsen from Triple-A Albuquerque.

Halvorsen might be the Rockies’ most talented reliever, but he’s had a tough time throwing strikes this year, walking 14 in 16 1/3 innings. He does have a 3.31 ERA anyway, but it’s going to be tough trusting him with leads right away.

Cubs selected the contract of RHP Vince Velasquez from Triple-A Iowa.

Velasquez made one appearance for the Cubs back in April, his first in the majors since 2023, pitching 2 1/3 scoreless innings before being designated for assignment and clearing waivers. The 34-uear-old has made six starts and four relief appearances for Iowa, amassing a 6.15 ERA and a 40/25 K/BB in 33 2/3 innings. He last worked five days ago, throwing 73 pitches, so if nothing else, he can provide some length in today’s doubleheader.

Cubs placed Edward Cabrera on the 15-day injured list with a hamstring strain.

Cabrera injured his hamstring when he accidentally did a split while covering first base on Tuesday night. He looked to be in a lot of pain and had to be removed from the game. The Cubs are sending him for imaging on Wednesday to see how long he will be out for.

Cubs placed RHP Ben Brown on the 15-day injured list with a neck strain.

The Cubs having to place both Ben Brown and Edward Cabrera (hamstring) on the injured list on the same day is quite a blow. They’ll get Matthew Boyd (knee) back tomorrow, but this rotation will still be super short-handed. The hope is that Brown won’t be sidelined for much longer than his two weeks.
