Garcia is not in the Nationals' starting lineup against the Phillies on Wednesday.

Garcia has been in the Nationals' starting nine against lefties a few times this season, but he'll begin Wednesday's game in the dugout while Amed Rosario starts at the keystone and bats in the leadoff spot against Phillies southpaw Cristopher Sanchez. Garcia has recorded at least one hit in five of his last six games, and over that span he has gone 7-for-21 with one stolen base, two runs scored and a solo homer.

Frazier is not in the Pirates' starting lineup against the Cubs on Wednesday.

The Cubs are sending a southpaw for a second straight game, so Frazier will retreat to the dugout while Jared Triolo starts at second base and bats eighth against Matthew Boyd. Frazier is in the midst of an 11-game hitting streak, going 12-for-33 (.364) with three stolen bases, five runs scored and two RBI over that span.

Farmer is out of the lineup for Wednesday's game against Atlanta.

Though the Rockies remain without Ezequiel Tovar (hip), Thairo Estrada (wrist), Aaron Schunk (groin) and Tyler Freeman (oblique) in the middle infield, Farmer no longer looks to be in the mix for regular playing time at second base or shortstop. He'll be on the bench for the fourth time in seven games, with the Rockies prioritizing Adael Amador ahead of him at the keystone and Alan Trejo at shortstop.

The Reds recalled Callihan from Triple-A Louisville on Wednesday. He'll start in left field and bat ninth in the first game of Wednesday's doubleheader versus the Cardinals.

He'll join the 26-man active roster as a replacement for corner infielder Jeimer Candelario (spine), who was placed on the 10-day injured list. The 24-year-old had gotten off to a nice start to the season at Louisville, slashing .303/.410/.528 with four home runs and six stolen bases over 106 plate appearances. Callihan is capable of playing three infield spots as well as left field, but his left-handedness could work against him in earning meaningful playing time, as he won't represent a viable platoon mate for fellow lefty hitters Jake Fraley and Gavin Lux.

Acuna went 2-for-4 with a steal and two runs scored in Tuesday's win over the Diamondbacks.

Acuna notched his second straight multi-hit game Tuesday with singles in the second and third innings, and he came around to score both times. He added his seventh steal of the season and is far and away the Mets' leading base stealer. The 23-year-old has held his own through the first month of the season, hitting .300/.355/.371 with five extra-base hits, three RBI, 13 runs and a 6:14 BB:K in 76 plate appearances.

The Reds plan to recall Callihan from Triple-A Louisville on Wednesday, Ari Alexander of KPRC 2 Houston reports.

After starting the Triple-A season with a .303/.410/.528 slash line alongside four homers, 12 RBI, 19 runs scored and six stolen bases through 106 plate appearances, Callihan will join the big-league club to provide Cincinnati with some depth at second base and left field. With Jeimer Candelario (back) and Austin Hays (hamstring) both currently dealing with injuries, Callihan's impending promotion seemingly indicates a move to the IL for at least one of the two players.

The Padres placed McCoy on the 10-day injured list Tuesday with a sprained finger on his left hand.

McCoy is 0-for-5 with three strikeouts since being recalled from Triple-A on April 21, and he'll now need to wait at least 10 days before getting another chance to record his first big-league hit of the season. Luis Arraez (concussion) will return from the injured list Tuesday to make up for the loss of McCoy in San Diego's infield.

Fitzgerald (chest) will start at second base and bat ninth in Tuesday's game against the Padres, Shayna Rubin of the San Francisco Chronicle reports.

A chest contusion has prevented Fitzgerald from playing in either of the Giants' last two games, but he seems to have fully recovered ahead of Tuesday's contest. The 27-year-old has slashed .294/.351/.412 over the past two weeks, though he is hitless in his last seven trips to the plate.

McNeil is not in the lineup for Tuesday's game against Arizona.

With lefty Eduardo Rodriguez on the bump for the Diamondbacks, McNeil will take a seat. In three games since returning from the injured list, McNeil has already seen action at second base and in center and right field. Luisangel Acuna is starting at second Tuesday.

Stott is not in the lineup for Tuesday's game against the Nationals.

With left-hander MacKenzie Gore on the mound for the Nationals, Stott will come off the bench Tuesday. Edmundo Sosa is getting the nod at second base and batting seventh.
