Harper was removed from Wednesday's game against the Blue Jays due to a left elbow contusion, Alex Coffey of The Philadelphia Inquirer reports.

The 31-year-old stayed in the game after being hit by a pitch in the left elbow during the first inning, though he was replaced by a pinch hitter for his second plate appearance. Harper is being further evaluated, which could include medical imaging. He should be considered day-to-day until more information is available.

Yepez is not in the lineup for Wednesday's game against the Marlins.

It's the second straight absence and third in four games for Yepez, with his only start during that stretch coming against a left-handed starter. Joey Gallo is starting at first base while Andres Chaparro serves as the designated hitter Wednesday against Miami righty Valente Bellozo, as it appears Yepez has fallen into the short side of a platoon, at least for the time being.

Harper revealed last week that he's been playing through a sore wrist and sore right elbow, MLB.com reports.

Harper was seen wincing after taking a swing in Tuesday's win over the Blue Jays, but he stayed in that game and is back in the lineup Wednesday. Phillies manager Rob Thomson said that Harper's elbow "grabs a little bit" on swings and misses, but he said his first baseman is "fine" and there are no current plans to give him rest. Harper noted last week that he's battled wrist soreness since May, while the elbow issue is more recent. He's slashing .307/.373/.465 since Aug. 1 but hasn't homered since Aug. 9.

Guerrero went 4-for-5 with a double, a two-run home run and a second run scored in Tuesday's 10-9 loss to the Phillies.

The first baseman led a 16-hit barrage for the Blue Jays and added his 28th homer of the season off Taijuan Walker in the sixth inning, but it wasn't enough. Guerrero is once again one of the hottest hitters in the majors, racking up seven multi-hit performance over his last nine contests while slashing .500/.550/.806 over that stretch with five doubles, two home runs, eight runs and eight RBI.

Gallo went 1-for-4 with a three-run homer in Tuesday's 6-2 victory over the Marlins.

Gallo widened Washington's lead to 4-0 in the fourth inning, smacking a first-pitch fastball from Max Meyer over the center field wall for a three-run homer. It's Gallo's sixth homer of the year and his first since June 3 -- he'd gone just 8-for-41 (.195) in his prior 16 contests. Overall, Gallo's slashing .172/.291/.331 with 17 RBI, 20 runs scored and a pair of stolen bases across 199 plate appearances in a part-time role this season.

Bell served as the designated hitter and went 0-for-4 with an RBI in Tuesday's 8-7 win over San Francisco.

Bell, who had been the primary first baseman for the last month, moved to DH as Christian Walker returned to first base after being activated off the 10-day injured list. Bell acquitted himself well as a replacement, batting .283 with an .809 OPS over 28 games, and should see work as the DH against left-handers going forward.

Walker went 1-for-5 with an RBI in Tuesday's 8-7 win over the Giants.

Walker was in the starting lineup on the day he was activated from the 10-day injured list. He missed the entire month of August because of an oblique injury. Walker is set to resume his role as the everyday first baseman.

Brown went 3-for-4 with a solo home run in Tuesday's 3-2 win over the Mariners.

Brown got the A's back level with a solo home run in the fourth and then supplied a walk-off single in the ninth off Trent Thornton. Over his last six starts, Brown has turned in five multi-hit games while racking up 10 RBI over that span. Since being brought back up to the majors July 11, he's slashing .320/.381/.557 with eight homers, 25 RBI, 15 runs and a 10:27 BB:K in 136 plate appearances.

Naylor left Tuesday's game versus the Royals with an acute back spasm, Joe Noga of The Cleveland Plain Dealer reports.

Naylor went 1-for-4 but exited in the eighth inning, with Jhonkensy Noel replacing him as a pinch runner and staying in the game at first base. Noel could see time at first base if Naylor is unable to play in Wednesday's series finale. Naylor has mostly avoided injuries this year, missing time with general soreness in late July.

Goldschmidt went 3-for-5 with a home run, a double, and three RBI in Tuesday's 7-4 victory at Milwaukee.

The former MVP stretched the St. Louis lead to 2-0 in the second with an RBI double, his 27th two-bagger of the season. Goldschmidt returned in the fourth inning to launch a 430-foot solo shot off Aaron Civale. The free-agent-to-be has caught fire lately, hitting .342 (26-for-76) with four homers, nine doubles, 13 RBI and five runs scored over his last 20 games. Overall, he is now slashing .247/.305/.420 with 21 homers, 58 RBI, 61 runs scored and nine stolen bases across 568 plate appearances.
