O'Hearn is not in the lineup for Wednesday's contest against the Nationals, Matt Weyrich of The Baltimore Sun reports.

Southpaw DJ Herz will toe the slab for the Nationals, so the left-handed-hitting O'Hearn will grab a seat. Austin Slater will occupy left field and Eloy Jimenez will start at designated hitter for the Orioles.

Martinez (elbow) will start at designated hitter and bat third in Wednesday's contest against the Athletics.

Martinez was lifted from Tuesday's game after being struck on the left elbow by a pitch, but he's back in there without having to miss any starts. The 36-year-old's production has fallen off since the start of July, as he's slashed just .221/.328/.354 across 33 contests.

Malloy is not in the lineup for Wednesday's game against the Mariners, Evan Woodbery of MLive.com reports.

Malloy has now sat out both contests since Kerry Carpenter was reinstated from the injured list Tuesday. Carpenter has served as the Tigers' designated hitter both times, so Malloy could see his playing time tick back up if Detroit elects to deploy Carpenter in right field more frequently down the road.

McCutchen is out of the lineup for Wednesday's game against the Padres.

With the Pirates wrapping up their series in San Diego with a day game after a night game, McCutchen will receive some routine maintenance. The 37-year-old has been in the midst of a heater to begin August, slashing .370/.485/.741 with three home runs, nine RBI and six runs over eight games.

Blackmon is out of the lineup for Wednesday's game against the Diamondbacks.

Blackmon went 0-for-4 while starting against lefty Eduardo Rodriguez in Tuesday's 4-3 loss, but the former will hit the bench for the series finale while Arizona sends another southpaw (Jordan Montgomery) to the bump. Hunter Goodman will replace Blackmon as the Rockies' designated hitter.

Ohtani went 1-for-5 with a solo home run in a 7-2 win against Milwaukee on Tuesday.

Ohtani gave Los Angeles a 2-0 lead in the third inning with a 413-foot solo shot. It was his 37th long ball of the campaign, most in the National League and second in the majors behind Aaron Judge (42). Ohtani also has 33 stolen bases, giving him a legitimate chance of recording the sixth 40-40 season in major-league history.

Calhoun went 1-for-4 with a solo home run in Tuesday's 6-1 loss to the Blue Jays.

Calhoun's ninth-inning blast prevented the Angels from getting shut out. The 29-year-old's playing time has been down lately due to a stretch heavy with left-handed starters for the Angels' opponents. It looks like Calhoun is in a strict platoon role at this point of the season. Overall, he has a .248/.316/.385 slash line, five homers, 20 RBI, 26 runs scored, 16 doubles and no stolen bases over 67 contests.

Madris went 2-for-4 with a walk, two RBI and two runs scored in Tuesday's 15-1 win over the Mariners.

Madris was ostensibly seen as a depth piece when he was called up from Triple-A Toledo in late July, but he's forced his way into regular playing time. The 28-year-old is batting .304 with five RBI and eight runs scored in 18 games for the Tigers. Madris may not be in the team's long-term plans, but he should continue to see the field plenty in the short term.

Martinez was removed from Tuesday's game against the Athletics after getting hit in the elbow by a pitch, Will Sammon of The Athletic reports.

Martinez took a 100-mph fastball off his left elbow during the second inning and remained in the game to run the bases, eventually coming around to score on a Jose Iglesias single. However, he was pinch hit for by Mark Vientos in the third frame. Martinez was able to escape the incident with only a bruise, so he shouldn't need to miss much time -- if any at all.

Pederson is out of the lineup for Tuesday's game against the Rockies, Alex Weiner of ArizonaSports.com reports.

Pederson has gone 10-for-30 with four homers through 10 games in August but will sit Tuesday as lefty Austin Gomber pitches for Colorado. Randal Grichuk will receive another turn at designated hitter as the two continue to platoon at the position.
