O'Hearn went 2-for-4 with a grand slam in Tuesday's victory over the Brewers.

O'Hearn electrified the crowd Tuesday with a first-inning grand slam off Bruce Zimmermann to put the Padres on top early. After a rough start to September, the slugger has locked back in, going 10-for-20 with eight RBI and a pair of extra-base hits across his past five games. While his post-deadline production has dipped to a .711 OPS since he left the Orioles, O'Hearn's overall season has been strong, with a .276/.362/.435 line, 20 doubles, 17 homers and 62 RBI across 140 games.

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

Vaughn will get a chance to rest Tuesday after going 2-for-3 with a walk and a run scored in Monday's extra-inning loss. Jake Bauers will get the nod at first base instead and bat seventh.

Phillies manager Rob Thomson said that Harper is absent from Tuesday's lineup versus the Marlins due to illness, Lochlahn March of The Philadelphia Inquirer reports.

The illness is bad enough to force Harper to miss his first start since July 2, but he should be ready to return to action in a day or two. Otto Kemp is at first base and batting ninth for the Phillies.

Harper is not in the lineup for Tuesday's game against the Marlins.

It's a rare day off for Harper, who had started every game since July 4. Otto Kemp will handle first base and bat ninth for the Phillies in Tuesday's series opener.

Chaparro went 2-for-5 with three RBI in Monday's loss to Atlanta.

Chaparro came through with a bases-clearing single off Chris Sale in the fifth inning to spark a rally, though Washington couldn't finish the comeback. The infielder has managed just a .520 OPS across 30 games, with Monday marking his first multi-RBI effort and only his third multi-hit showing of the season.

Vaughn will start at first base and bat sixth in Monday's game against the Padres.

Vaughn had been briefly overtaken by Jake Bauers as the Brewers' primary first baseman, but it will be Vaughn holding down first base Monday for the fifth time across the last seven contests. The 27-year-old Vaughn is slashing .415/.458/.561 in September, though he's yet to go deep this month.

Bauers is not in the lineup for Monday's game in San Diego.

Bauers had a recent stretch with four straight starts at first base, but he'll yield the position to Andrew Vaughn on Monday for the fifth time across the last seven tilts. The 29-year-old Bauers did draw one start in left field during the latter stretch, but he looks to have fallen back behind Vaughn on the first-base depth chart.

Wagaman is out of the lineup for Sunday's game against the Rangers.

After seeing his seven-game hitting streak end with an 0-for-3 showing in Saturday's 4-3 win, Wagaman will hit the bench Sunday. The 28-year-old should continue to play regularly against left-handed pitching during the final week of the season, though he may have to settle for a part-time role against right-handed pitching after the Marlins recently welcomed back fellow infielders Connor Norby and Graham Pauley from the 10-day injured list.

Stewart is out of the lineup for Sunday's game against the Cubs.

On the bench for the third game in a row, Stewart appears to have faded into a utility infield role while Spencer Steer has regained control of primary duties at first base. The Reds will still likely find room for Stewart in the lineup against left-handed pitching, but the rookie's opportunities to play against righties could be sporadic over the final week of the regular season.

Bauers is out of the lineup for Sunday's game against the Cardinals.

The left-handed-hitting Bauers will take a seat against left-hander Matthew Liberatore, allowing Andrew Vaughn to draw the start at first base. Bauers has taken hold of the strong side of a platoon at first base with Vaughn as the regular season winds down.
