Singleton isn't in the Astros' lineup for Saturday's game against Boston, Matt Kawahara of the Houston Chronicle reports.

Singleton will get a breather Saturday after going 2-for-5 with an RBI during Friday's win. Zach Dezenzo will fill in as Houston's first baseman and bat seventh.

Nevin (migraine) will start at first base and bat eighth Saturday versus the Blue Jays.

Migraines have prevented Nevin from playing in Oakland's last two games, but he seems to be feeling better ahead of Saturday's contest. The 27-year-old has slashed .188/.333/.313 across 21 plate appearances since the All-Star break.

Naylor went 1-for-4 with a three-run home run in a 6-3 loss to the Twins during the second game of Friday's doubleheader.

Naylor put the Guardians ahead 3-2 in the fifth inning, but Minnesota shot right back with a Matt Wallner three-run blast in the bottom of the frame. In the matinee, a 4-2 loss for Cleveland, Naylor was 0-for-4 with two strikeouts. The first baseman has four homers and 12 RBI over his last 10 games, going 10-for-38 (.263) in that span. Overall, he has 26 homers, 85 RBI, 66 runs scored, 18 doubles, five stolen bases and a .243/.322/.484 slash line through 108 games this season.

Freeman went 2-for-3 with a solo home run, a double, a walk, a stolen base and two total runs scored in Friday's 9-5 win over the Pirates.

Freeman did a bit of everything in his second consecutive multi-hit effort. The homer was his first since July 21. The first baseman has gone 6-for-15 with four RBI over four games since returning from an absence due to a personal issue. Overall, Freeman is sporting a .292/.396/.503 slash line with 17 homers, 71 RBI, 66 runs scored, six steals, 28 doubles and two triples across 108 contests.

Busch is out of the lineup for Friday's game against the White Sox.

Busch had started the Cubs' first seven games of August -- going 7-for-24 with three homers -- but will get some rest Friday. In his place, Patrick Wisdom will play first base and bat second.

Red Sox manager Alex Cora indicated Friday that Casas (ribs) will be activated from the 60-day injured list whenever the first baseman feels his timing at the plate is ready, Alex Speier of The Boston Globe reports.

Casas is 8-for-25 with five doubles and a 7:2 K:BB over six rehab games with Triple-A Worcester. It sounds like the team is no longer concerned about whether Casas is ready physically and now it's just about knocking a little more rust off. While the news is relatively vague in terms of a potential timetable, it would appear Casas could be back any day now. He's been sidelined since late April with a cartilage tear in his left ribcage.

Mountcastle is not in the lineup for Friday's contest versus the Rays, Jake Rill of MLB.com reports.

It's a regular day off for Mountcastle, who currently possesses a modest five-game hitting streak. Ryan O'Hearn will handle first base duties for the Orioles.

Nevin (migraine) is out of the lineup for Friday's game against the Blue Jays.

Nevin was scratched from Wednesday's game against the White Sox due to a migraine. After Thursday's team off day, he remains out of the starting nine. Considering Nevin had started in merely one of the Athletics' previous six games, his absence from the lineup perhaps isn't related to Wednesday's migraine.

Walker (oblique) is not yet asymptomatic, Alex Weiner of Arizona Sports reports.

Walker, who landed on the 10-day injured list July 30 with a left oblique strain, could pick up a bat next week. The Diamondbacks are cognizant that oblique injuries are tricky for a baseball player and want Walker to be 100 percent before really ramping up. Arizona is getting by at first base with trade deadline acquisition Josh Bell, so the team doesn't need to rush Walker back.

Goldschmidt went 1-for-2 with two RBI and a stolen base in Thursday's loss to the Rays.

Goldschmidt drove home Nolan Arenado on a groundout in the opening frame before adding an RBI single in the third, giving the first baseman only his second multi-RBI game since June 22. The single also snapped an 0-for-19 skid for Goldschmidt, and he's batting a putrid .154 (4-for-26) to begin August with one homer, four RBI and two runs scored.
