Polanco is not in the lineup for Thursday's game against the Orioles.

Polanco was given a semi-day off Wednesday in the designated hitter slot and will be out of the lineup altogether Thursday. Ryan Bliss is getting the start at second base for the Mariners.

Edman (wrist) will take live batting practice Friday and Saturday at Double-A Springfield, Lynn Worthy of the St. Louis Post-Dispatch reports.

If that goes well, Edman should be cleared to begin a rehab assignment with Springfield. Edman was recently set back a few days by a sprained ankle, but that appears to be a non-issue now. The Cardinals had been hoping to get Edman back prior to the All-Star break, but it's possible the little hiccup with the ankle last week will convince the club to push Edman's return back until the start of the second half. He's been out all season while recovering from wrist surgery.

Horwitz is out of the lineup for Thursday's game against the Astros.

Hortwitz will head to the bench Thursday with lefty Framber Valdez on the mound for Houston. Leo Jimenez will man second base and bat eighth in the series finale.

Semien is absent from the lineup for Thursday's game against the Padres.

It's just the second day off of the season for Semien, who has managed just two hits over his last 36 at-bats. Jonathan Ornelas will handle second base for the Rangers on Thursday while Semien receives some much-needed rest.

The Marlins placed Lopez on the 10-day injured list Thursday due to lower-back inflammation, Jordan McPherson of the Miami Herald reports.

The 25-year-old was held out of the lineup the past two days and will now take at least another week to get healthy on the injured list. Jonah Bride was called up in a corresponding move, and he could see time at second base along with Vidal Brujan while Lopez is sidelined.

Gorman is not in the lineup for Thursday's contest in Pittsburgh.

Left-hander Martin Perez is drawing the start on the mound for the Pirates, so the lefty-hitting Gorman will begin this one on the bench. Jose Fermin will occupy second base for the Cardinals.

Garcia is absent from the lineup for Thursday's game against the Mets.

Garcia slugged a pair of home runs in Wednesday's win over the Mets but nonetheless finds himself on the bench a day later with southpaw Jose Quintana on the hill. Ildemaro Vargas will be at second base for the Nationals.

Garcia went 2-for-3 with two home runs, a walk, three total runs and four RBI in Wednesday's 7-5 win against the Mets.

Garcia hit a three-run shot in the sixth inning and added a solo blast in the eighth. It was the second multi-homer game of the infielder's career, and the four RBI tied a season-high mark. Garcia has already matched the career-high total of nine long balls he accumulated last year, and he's 10 shy of his career-best mark of 50 RBI, which he also reached last season.

Ornelas was scratched from the lineup for Wednesday's game against the Padres.

The 24-year-old was set to receive his second straight start at third base Wednesday, but shortstop Corey Seager's (wrist) late addition to the lineup will push Josh Smith back to the hot corner. Ornelas went 1-for-2 with a walk, a double and an RBI on Tuesday but may not stick around the roster much longer if Seager is fully recovered.

Mateo is not in the starting lineup for Wednesday's game against the Mariners.

Mateo has gone 0-for-7 with one walk and two strikeouts over his last two games, and he will begin Wednesday's contest on the bench. Jordan Westburg and Ramon Urias will start at second and third base, respectively.
