The Mets activated Alvarez (thumb) from the 10-day injured list Tuesday, Mike Puma of the New York Post reports.

Alvarez has been sidelined since late April with a fractured left thumb but is ready to roll after playing in six rehab games. It's possible the Mets will ease him back into everyday action with some extra off days mixed in, but he will immediately regain his role as the club's primary catcher. Alvarez was slashing .236/.288/.364 with one home run in 16 contests before getting hurt.

Marchan was recalled from Triple-A Lehigh Valley on Tuesday.

The 25-year-old was with the Phillies as the 27th man for the two-game series versus the Mets in London, and he's now fully on the big-league roster with J.T. Realmuto (knee) landing on the injured list. Marchan hasn't seen MLB action since 2021, but that will change the first time he operates as the backup to fill-in catcher Garrett Stubbs.

The Phillies placed Realmuto on the 10-day injured list Tuesday with right knee pain, and he's scheduled to undergo a meniscectomy Wednesday.

According to Matt Gelb of The Athletic, Realmuto has been playing through the injury for nearly a month, and the Phillies elected to address the injury now rather than attempting to wait things out. Gelb also reports that Realmuto will miss roughly a month, potentially setting him up for a mid-July return from the shelf. Rafael Marchan was called up from Triple-A Lehigh Valley in a corresponding move and should serve as the backup catcher to Garrett Stubbs.

Rockies manager Bud Black suggested after Monday's 5-0 loss to the Twins that Diaz will likely miss the remaining two games of the series in Minnesota due to a strained left calf, MLB.com reports. "It's right in the belly of the calf, so we'll see," Black said of the injury Diaz suffered in the first inning of Monday's game. "He's been feeling it for a couple weeks. He's been able to manage it and [in Monday's game], I think just on that particular ground ball, out of the box, it got him. We'll see in a couple of days. Keith [Duggar, the team's head athletic trainer] wants to treat it for a day or two and see where we are."

Diaz was lifted from the game in the bottom of the first after he strained his calf while running out a groundball in his first at-bat of the night in the top of the frame. Jacob Stallings came on to replace Diaz and will presumably start behind the plate for the final two games in Minnesota, and Stallings could be headed for an extended run as the Rockies' No. 1 catcher if Diaz requires a stint on the injured list. Diaz will presumably be re-examined Thursday when the Rockies return to Colorado before the team makes a decision on his availability heading into this weekend's series versus the Pirates. Diaz has been one of the few bright spots for the Rockies this season, batting .303 with five home runs, 28 RBI and 20 runs in 55 games.

Diaz left Monday's game against the Twins due to a left calf injury, Luke Zahlmann of The Denver Gazette reports.

Diaz is likely undergoing additional testing to uncover the extent of the calf injury. Jacob Stallings and Hunter Goodman would share time behind the plate if it's determined Diaz requires an extended absence, though it's still too early to know if he'll be placed on the injured list.

Diaz (undisclosed) was removed from Monday's contest against the Twins, Luke Zahlmann of The Denver Gazette reports.

Diaz pulled up lame on a groundout in the top of the first inning, being replaced at catcher by Jacob Stallings prior to the bottom of the frame. The team will likely provide an update to Diaz's status following Monday's series opener.

Maile went 1-for-4 with a solo home run in Sunday's 4-2 loss to the Cubs.

The Reds' offense busted out the last week during the club's seven-game winning streak but was dormant Sunday. Maile launched his second homer and has hit safely in seven of the last nine games (7-for-23, .304).

The Phillies returned Marchan to Triple-A Lehigh Valley on Monday.

Marchan will head back to Lehigh Valley after he joined the Phillies over the weekend and served as the club's 27th man for its two-game set in London versus the Mets. He didn't appear in either contest and hasn't seen any big-league action since 2021.

Ruiz went 1-for-3 with a home run and four RBI Sunday against Atlanta.

Ruiz hammered a three-run blast in the fourth to give the Nationals a lead they would never relinquish. He later added a fourth RBI on a sac fly in the fifth that provided the Nationals with their eighth and final run of the contest. It was the fourth homer of the season for Ruiz to go along with 17 RBI and 16 runs as he's struggled to a .202 average through 163 at-bats.

Pages went 1-for-2 with a walk, one RBI and two runs scored in Sunday's 5-1 win over the Rockies.

Pages' RBI came on a sacrifice fly in the second inning to open the scoring. The backup catcher has had few chances to make an impact, and he's rarely done so even when in the lineup. He's slashing .091/.241/.136 with no home runs, five RBI, three runs scored and a double over 29 plate appearances this season. Ivan Herrera seems set to hold down a starting job at catcher until Willson Contreras (forearm) returns, at which point Pages is likely ticketed for Triple-A Memphis.
