Wagaman went 3-for-5 with a double, two runs scored and two RBI in Friday's 9-7 loss to the Astros.

The 27-year-old is having a nice finish to the season in his first look at big-league pitching. Over the last seven games, Wagaman's batting .355 (11-for-31) with four doubles, two homers, five runs and seven RBI, and he's at least put himself in position to compete for a regular spot on the 26-man roster next spring.

Singleton is not in the lineup for Friday's game versus the Angels, Matt Kawahara of the Houston Chronicle reports.

It's southpaw Tyler Anderson on the bump for the Angels, so the left-handed-hitting Singleton will grab a seat to begin the festivities. Yainer Diaz will draw the start at first base for the Astros and Victor Caratini will catch.

Mountcastle (wrist) reported to Triple-A Norfolk to begin a rehab assignment Friday, Matt Weyrich of The Baltimore Sun reports.

The 27-year-old will get in a few games at Triple-A this weekend before potentially rejoining the Orioles early next week. Mountcastle has been sidelined nearly a month due to a sprained left wrist but should give Baltimore a boost for the final days of the regular season.

Schanuel went 1-for-3 with a walk and a stolen base in Thursday's loss to Houston.

Schanuel walked in his first trip to the plate and eventually stole third base after advancing to second on a Brandon Drury single. The first baseman would later add a single of his own to lead off the sixth, extending his hitting streak to 10 games in the process. Schanuel is batting .388 (14-for-36) over that 10-game stretch with one homer, seven RBI and three runs scored.

Guerrero went 3-for-4 with two solo home runs, an additional run scored and a walk Thursday against the Rangers.

Each of Guerrero's blasts went for over 400 feet, raising his season homer total to 30. The first of those homers snapped a 49 at-bat homer-less streak. It was the first multi-homer game of the season for Guerrero and the 19th time he's collected at least three hits in a game. The veteran first baseman stands just one RBI shy of his second 100-RBI season, while his .322 average is a career best and ranks second in the majors behind only Bobby Witt.

Kavadas is not in the lineup for Thursday's game in Houston.

It will be southpaw Yusei Kikuchi drawing the start on the mound for the Astros, so the lefty-hitting Kavadas will begin the festivities on the bench. Brandon Drury will handle designated-hitter duties for the Angels.

Naylor went 2-for-4 with a pair of solo home runs and an additional run in Wednesday's 5-4 extra-inning win against the Twins.

Naylor got to Minnesota starter Bailey Ober twice, touching up the right-hander for solo shots in the second and seventh frames. The power display ended a 13-game homerless drought for the first baseman and marked his third multi-homer performance of the campaign. Naylor is up 31 home runs and 105 RBI on the season, both of which are career highs.

Vaughn went 1-for-5 with a solo home run in Wednesday's 4-3 extra-innings loss to the Angels.

The first baseman took Jack Kochanowicz deep in the fourth inning to get the White Sox on the board. The blast added to Vaughn's impressive September, and he's batting .345 (19-for-55) on the month with four homers and eight RBI in 14 games. It's been a roller coaster of a season for the 26-year-old, but he now sits one long ball short of his second straight 20-homer campaign.

Soderstrom went 2-for-4 with a home run, two runs scored and two RBI in Wednesday's 5-3 win over the Cubs.

He got the A's on the board in the fourth inning with a solo shot off Ethan Roberts. It was Soderstrom's first homer in four games since being activated from the IL, and his eighth of the year in 53 contests. With four hits in two games during this series at Wrigley Field, the 22-year-old has boosted his slash line on the season to .224/.304/.410.

Gurriel will start at first base and bat fifth in Wednesday's game against the Tigers.

Gurriel will pick up his fourth consecutive start and looks to have settled in as Kansas City's primary option at first base. Since being acquired from Atlanta on Aug. 31, Gurriel has slashed .348/.414/.435 with five runs and four RBI through his first nine games with the Royals.
