Naylor went 2-for-4 with a double and three RBI in Tuesday's win over the Rockies.

Naylor came through in the clutch, ripping a bases-clearing double with two outs in the eighth inning to put the Mariners ahead and help secure a postseason berth. Since arriving from the Diamondbacks at the trade deadline, he's maintained his production, posting an .819 OPS in Seattle after logging an .807 mark in Arizona. For the season, the first baseman owns a .292/.351/.461 slash line with 28 doubles, 20 homers, 91 RBI and 28 stolen bases across 144 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.

The Blue Jays placed France on the 10-day injured list Tuesday with left oblique inflammation.

France's injury will force him to miss the remainder of the regular season, though he will be eligible to return before the start of the ALDS. His move to the IL will clear a roster spot for Anthony Santander (shoulder), who was activated from the 60-day IL in a corresponding move.

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.

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.
