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.

Guerrero went 2-for-5 with a two-run double and a run scored during the Blue Jays' 8-5 win over the Royals on Sunday.

Guerrero entered Sunday's game having gone just 4-for-27 (.148) over his past seven outings. He was better at the plate in Sunday's series finale and gave the Blue Jays a three-run lead in the fifth with a two-run double before coming home to score on an Addison Barger RBI double. Since the All-Star break, Guerrero has a .953 OPS with one steal, 11 home runs and 37 RBI over 242 plate appearances.

Burger is out of the lineup for Sunday's game against the Marlins.

Burger and Rowdy Tellez have now split playing time at first base against right-handed pitching over the past four games, with both players garnering two starts apiece. Though Burger appeared to have settled in as the primary first baseman upon his return from the injured list Sept. 1, he's gone 0-for-13 with seven strikeouts over his last four contests and seems to have lost some job security in the process.

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.

Eldridge went 1-for-3 with three RBI, a double, a walk and a run scored in Saturday's 7-5 loss to the Dodgers.

Eldridge hit a three-run double to left field in the first inning before coming around to score, giving the Giants an early 4-0 lead. It was the 20-year-old's first major-league hit after going 0-for-9 in his first three games. Before being called up to the majors, Eldridge slashed .249/.322/.514 with 63 RBI, 31 runs scored, 18 long balls and a stolen base across 286 plate appearances for Triple-A Sacramento.
