The Athletics placed Gelof on the 10-day injured list Thursday with a strained left oblique.

Gelof's injury caused him to be a late scratch from Oakland's lineup ahead of Wednesday's game, and it will now officially cost him at least another week and a half. The 24-year-old second baseman hadn't missed a start prior to Wednesday, though he's failed to make the most of his playing time, slashing just .196/.260/.337 with seven RBI across his first 101 plate appearances. Darell Hernaiz was recalled from Triple-A Las Vegas in a corresponding move.

Lux is out of the lineup for Thursday's game against the Nationals.

With the Dodgers and Nationals concluding their series with a day game after a night game and with southpaw MacKenzie Gore on the bump for Washington, Lux is one of three lefty-hitting regulars who will get the afternoon off for Los Angeles. Lux will be joined on the bench by Max Muncy and James Outman.

Biggio is out of the lineup for Thursday's game against the Royals.

With the Blue Jays and Royals concluding their series with a day game after a night game and with a southpaw (Cole Ragans) on the hill for Kansas City, the lefty-hitting Biggio will get the afternoon off. Isiah Kiner-Falefa will step in for Biggio at the keystone.

Valdez is out of the lineup for Thursday's game in Cleveland.

Valdez is getting a routine day off after starting at second base in each of the Red Sox's previous nine contests. David Hamilton will handle the keystone Thursday.

Mead went 1-for-3 with a two-run home run in Wednesday's 7-5 win over the Tigers.

The 23-year-old took Will Vest deep in the sixth inning to break open a 5-5 tie. It was Mead's first homer, and first extra-base hit, of the season, but he could be running out of time to solidify his spot in the lineup with Brandon Lowe (oblique) and Jonathan Aranda (finger) on track to return in early May. Over the last 12 games, Mead is batting just .216 (8-for-37) with a 1:10 BB:K.

Polanco went 1-for-3 with a walk and a stolen base in a loss to the Rangers on Wednesday.

Polanco's struggles at the plate continued for the most part, with his average now sitting at a paltry .175 through 99 plate appearances. However, the veteran also sports a surprisingly solid .333 on-base percentage that's largely the result of his 18.9 percent walk rate. The free pass he drew Wednesday also led to his first stolen base of the campaign, and the combination of Polanco's career-low .234 BABIP and above-average 24.0 percent line-drive rate seems to imply his luck when putting the ball in play should start to turn soon.

India (illness) will serve as the Reds' designated hitter and No. 6 batter in Thursday's game against the Phillies.

India is back in the starting nine for the first time since Saturday, albeit in a non-defensive role as the Reds look to ease him back in following his bout with an illness that kept him on the bench for four games. He'll likely reprise his usual duties at second base over the weekend, at which point Santiago Espinal will head back to the bench and serve as a utility infielder.

Kennedy went 1-for-4 with a run scored, an RBI and a stolen base in Wednesday's 7-5 loss to the Rays.

Getting the start at second base and batting seventh with Tampa Bay southpaw Tyler Alexander set for a bulk relief outing, Kennedy swiped his first career base in the majors while collecting his second hit since his promotion. The 25-year-old has supplied a homer and four RBI in four games, and he could spot in around the Tigers' injury-weakened infield more often than expected if he continues to produce.

Espinal started at second base and went 2-for-3 with three RBI and a run scored in Wednesday's 7-4 win over Philadelphia.

Espinal has feasted on Phillies' pitching, going 5-for-7 with a home run and five RBI over the first two games of the series. It was his fourth straight start at second base in place of Jonathan India (illness), but the ailing India was available off the bench Wednesday and presumably will be available for the series finale Thursday afternoon.

Altuve went 1-for-5 with a solo home run Wednesday in a loss to the Cubs.

Altuve launched a solo blast off closer Hector Neris in the ninth inning to bring the Astros to within a run, but the team ultimately fell short. The long ball was Altuve's sixth of the season, though he has only eight RBI. The star second baseman is otherwise having a fantastic campaign, slashing .350/.412/.602 with 17 runs and three stolen bases.
