Martinez went 1-for-4 with a three-run home run in Tuesday's loss to the Orioles.

The veteran slugger got hold of a Burch Smith fastball in the eighth inning and drove it over the fence in right-center field, bringing the Mets to within two runs, but it was as close as they got in an eventual 9-5 defeat. Martinez has gone yard in back-to-back games, giving him 14 homers on the year, but through 17 games in August he's slashing just .211/.318/.439 as the 37-year-old continues to struggle to provide consistent offense.

O'Hearn is out of the lineup for Wednesday's game against the Mets.

The Mets are bringing a left-hander (Sean Manaea) to the hill for the third straight game, and the lefty-hitting O'Hearn has been on the bench for each of those contests. O'Hearn could be a candidate to replace starting left fielder Austin Slater or designated hitter Eloy Jimenez at some point during the contest once Manaea exits.

Pederson went 1-for-2 with a walk, an RBI and a stolen base in Tuesday's 3-1 win over the Marlins.

Pederson made Miami starter Edward Cabrera pay for a first-inning balk, as he connected on a run-scoring single to put the Diamondbacks on top early. It was the fifth consecutive game with a run driven in for Pederson. He later stole his sixth base of the season, tying the career high he set in 2016.

Larnach isn't in the Twins' lineup for Tuesday's game against the Padres.

With left-hander Martin Perez set to throw the first pitch for San Diego on Tuesday, the lefty-hitting Larnach will step out of the lineup. Manuel Margot will get the starting nod in left field instead and bat leadoff.

O'Hearn is out of the lineup for Tuesday's game against the Mets, Roch Kubatko of MASNSports.com reports.

Jose Quintana is the second straight lefty to start for New York, so O'Hearn finds himself on the bench again Tuesday. Eloy Jimenez is batting fifth as the designated hitter as the two continue to platoon the position.

The Cardinals recalled Baker from Triple-A Memphis on Tuesday.

Baker has slashed .231/.345/.535 with 32 home runs in 108 games this season at Memphis, which includes a 1.096 OPS versus left-handed pitching. The 27-year-old is blocked by Paul Goldschmidt at first base but figures to see some looks at designated hitter against southpaws.

The Cardinals reinstated Carpenter (back) from the 10-day injured list Tuesday.

The 38-year-old will end up missing only the 10-day minimum due to a back strain. Carpenter went 0-for-2 with two walks and two strikeouts in his lone start of August prior to landing on the shelf, and he's unlikely to see consistent at-bats for the Cardinals down the stretch.

The Nationals optioned Blankenhorn to Triple-A Rochester on Tuesday.

Blankenhorn's playing time had been trending downward throughout August, and he'll give up his spot on the 26-man roster to Joey Gallo (hamstring), who was activated from the injured list Tuesday. Blankenhorn posted a meager .317 OPS in 32 plate appearances for the Nationals but is slashing .246/.328/.518 with Rochester.

Pederson went 1-for-3 with a walk, a solo home run and an additional run scored in Monday's 9-6 win over the Marlins.

Pederson swatted his 20th home run of the season in the fifth inning, giving him at least one RBI in four consecutive games. The lefty-swinging designated hitter is turning in a strong second half, posting a line of .356/.500/.780 over 23 games since returning from the All-Star break.

Yoshida went 1-for-2 with a two-run home run in a loss to Houston on Monday.

Yoshida began the game on the bench but pinch hit for Connor Wong in the sixth inning. The 31-year-old came through with a big knock, swatting a two-run homer to left field to give Boston a two-run lead. The long ball also extended Yoshida's hitting streak to seven games, during which he's batting an absurd .632 (12-for-19) with two homers, six RBI, six runs and four walks.
