Singleton isn't in the Astros' lineup for Saturday's game against the Diamondbacks, Chandler Rome of The Athletic reports.

Singleton will get a breather Saturday after going 3-for-15 with two home runs and three RBI across his last five games. In his absence, Yainer Diaz will cover first base while Victor Caratini starts behind the dish and bats sixth.

Turner went 2-for-5 with a double in a win over the Cardinals on Friday.

The veteran extended his recent stretch of hot hitting with Friday's production, which pushed his average over the last seven games to .320 (8-for-25). Turner has three of his five extra-base hits with the Mariners in that span, and he's also striking out at just a 10.0 percent clip within that sample of 30 plate appearances.

Naylor (back) went 0-for-4 with two strikeouts Friday against the Dodgers.

He exited Tuesday's game with an acute back spasm but only missed a few days. Naylor has been locked into the four hole against righties and the five hole against lefties while slashing .245/.324/.426 with four home runs and one steal over his last 25 games.

Brown went 2-for-2 with a two-run home run and an additional RBI in Friday's 7-6 extra-innings win over the Tigers.

Brown didn't start Friday, but he was one of four Athletics with multiple hits in the marathon game. The 32-year-old saved the day in the 11th inning with a game-tying homer, then came up big again with the walk-off hit, a single, to plate JJ Bleday in the 13th. Brown has seven multi-hit efforts over his last 10 games, going 16-for-35 (.457) with four homers and 14 RBI in that span. The surge has him up to a .251/.310/.421 slash line with 14 homers, 44 RBI, 29 runs scored and four stolen bases through 106 contests overall.

Brown is not in the starting lineup for Friday's game against the Tigers.

He's been swinging a hot bat over the past couple weeks, slashing .391/.442/.630 with three homers and 12 RBI in his last 13 games, but Brown remains a strict platoon player for manager Mark Kotsay. In fact, Brown has made just a single start against a lefty this season. Tarik Skubal starts for Detroit in the series opener.

Mountcastle (wrist) hit off a tee Friday, Roch Kubatko of MASNSports.com reports.

Manager Brandon Hyde said Mountcastle is making a little progress but did not offer a timeline for his return. This marks the first reported time Mountcastle has swung a bat since going on the injured list Aug. 26 due to a sprained wrist. Ryan O'Hearn has been starting at first base while Eloy Jimenez mans designated hitter most days.

Gurriel (hamstring) is starting at first base and batting seventh Friday against the Twins.

He left Monday's game with hamstring tightness and made an appearance off the bench Wednesday. Gurriel is batting .333 with one run and one RBI in three games with the Royals.

Dezenzo was optioned to Triple-A Sugar Land on Friday.

Dezenzo had a max exit velocity of 109.1 mph and hit one homer in 55 plate appearances with the big club, but he was largely overmatched. The hulking 6-foot-4 corner infielder hit .212 with a 32.7 percent strikeout rate and a 5.5 percent walk rate while playing sparingly after an Aug. 6 promotion.

Soderstrom (wrist) went 1-for-3 as the designated hitter in Triple-A Las Vegas' win over Round Rock on Thursday, hitting a two-run home run.

Soderstrom was making his first rehab appearance and slugged the round tripper in his final plate appearance of the game in the sixth inning. It was the rookie's first taste of game action since July 9, and he'll need to see action on defense before his activation from the IL is considered.

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

It's lefty Cody Bradford on the bump for the Rangers, so the lefty-hitting Kavadas will begin the series opener on the bench. Brandon Drury will occupy the designated hitter slot.
