Atlanta selected Leon's contract from Triple-A Gwinnett on Monday.

With both Sean Murphy and Drake Baldwin playing regularly between the catcher and designated-hitter spots, the club has elected to add Leon to the roster as a third backstop. A 12-year major-league veteran, Leon last appeared in the big leagues in 2023.

Moreno will undergo a CT scan this week to check the healing of the hairline fracture in his right index finger, MLB.com reports.

If the scan shows that Moreno has made sufficient progress, he could be allowed to begin some baseball activities. Moreno was moved to the 60-day injured list over the weekend, making him ineligible to return to the Diamondbacks' 26-man active roster until mid-August.

Caratini went 3-for-5 with a two-RBI double and an RBI single during Sunday's 11-3 win over the Mariners.

Caratini drove in at least three Astros for the fifth time this season and notched his sixth three-hit game of the year. The 31-year-old has recorded a hit in 12 of his 13 games in July, going 20-for-52 with four homers and 17 RBI. He's slashing .272/.321/.447 overall.

Diaz went 2-for-5 with a two-run home run in Sunday's 8-1 win over the Nationals.

Diaz chased MacKenzie Gore with a two-run homer in the third inning and later added a single in the seventh. It was a much-needed effort for the 34-year-old, who entered Sunday in an 0-for-17 slump to begin July. For the year, he's slashing just .198/.270/.307 with five home runs, 16 RBI and 23 runs scored across 214 plate appearances while sharing time behind the plate with Martin Maldonado.

Perez went 2-for-4 with a solo home run, a double and two runs scored in Sunday's win over Miami.

Perez knocked a double and scored a run in the fourth inning before adding an insurance run with his solo shot in the eighth. He's up to 15 homers this season, including two during the three-game series against Miami and six in his last 10 appearances. The veteran slugger has gone 14-for-34 (.412) during that 10-game stretch, boosting his season slash line to .251/.294/.444 through 391 plate appearances.

Alvarez is expected to be called up from Triple-A Syracuse on Monday, Mike Puma of the New York Post reports.

Alvarez will return to the major-league roster after being sent down to Syracuse on June 22. The catcher caught fire at Triple-A, batting .299 with 11 home runs, 24 RBI and 17 runs scored over 19 contests following his demotion. Alvarez will now compete with Luis Torrens for starts behind the plate with the Mets.

The Astros optioned Salazar to Triple-A Sugar Land on Sunday, Brian McTaggart of MLB.com reports.

Salazar has been up with the Astros as a third catcher since early May, though he's played in just eight games and gone 1-for-7 during his two-plus months in the majors. The 29-year-old is likely to stick with Sugar Land as long as Yainer Diaz and Victor Caratini stay healthy.

Smith isn't starting against the Brewers on Sunday.

Smith started the Dodgers' first two games coming out of the All-Star break, going 3-for-8, but he'll get a breather for Sunday's afternoon affair. Dalton Rushing is starting behind the plate and batting ninth in the series finale against Milwaukee.

Wells is out of the lineup for Sunday's game against Atlanta.

Wells went 1-for-8 with an RBI and a run while starting the first two games of the series and will take a seat for Sunday's finale. Ben Rice will instead do the catching for Marcus Stroman and bat seventh.

Realmuto is not in the starting lineup for Sunday's matchup versus the Angels.

Realmuto will get a breather after starting each of Philadelphia's previous six contests. Rafael Marchan is getting the start behind the plate in the series finale versus Los Angeles.
