Willie Bloomquist will undergo an MRI on his right knee Thursday.
Bloomquist hurt the knee while running to first base on Wednesday. He's already been placed on the disabled list, but a timetable for his return won't be known until the MRI results come back.
Jeff Samardzija limited the Astros to one run and five hits over eight innings in a victory Thursday.
Samardzija struck out six and walked none against the accommodating Astros lineup. As a member of the Cubs, Samardzija went winless in six starts this year when he allowed one or no runs. He's now 2-0 for the A's in such outings.
Mariners manager Lloyd McClendon said Thursday that Chris Taylor will "get his fair share of playing time."
It's not quite coming out and saying that he'll take over as the everyday shortstop, but Taylor didn't come up to sit. The 23-year-old has batted .328/.397/.497 with five home runs and 14 stolen bases in 75 games this season at the Triple-A level and is worth a shot in deeper formats. Brad Miller will see his playing time cut.
Scott Feldman was tagged for six runs in 5 1/3 innings by the A's in Thursday's loss.
The last two of those runs came after he was pulled in the sixth. That was some odd timing: he was allowed to face three straight left-handed hitters to start the inning and retired the last of them, but then he was pulled when Josh Donaldson came to the plate. Feldman has just one win in his last 10 starts, and he's 4-8 with a 4.60 ERA overall. It's disappointing, for sure, but then, it matters more to the Astros how he pitches in 2015 and '16 than it does this year.
Manny Machado (back) remained out of the Orioles' lineup Thursday.
It's the third straight contest he's missed with tightness in his lower back. Machado received an anti-inflammatory injection on Tuesday, so hopefully the shot just needed a couple days to take effect. The third baseman remains day-to-day for the time being.
Brandon Moss hit his third grand slam of the year Thursday off the Astros' Anthony Bass.
Moss never had a slam in 41 at-bats with the bases loaded prior to this season. This year, he's 5-for-8 with 17 RBI in those situations. He has 23 homers and 71 RBI overall, putting him in the top 10 in the AL in both categories.
Jed Lowrie went 3-for-5 with an RBI versus the Astros on Thursday.
Lowrie has warmed back up of late after down months in May and June. He is hitting .357 with two homers and eight RBI in 10 games against the Astros this year.
Astros general manager Jeff Luhnow indicated Thursday that the team is unlikely to trade Chad Qualls.
Teams have expressed interest in the reliever, but Qualls will make a reasonable $6 million through the end of next season and has a $3 million option for 2016, so Luhnow doesn't feel compelled to move him. The 35-year-old boasts a terrific 1.78 ERA and 31/4 K/BB ratio over 35 1/3 innings in 2014. "I hesitate to use the word 'untouchable,' but he likes it here, he's comfortable here and he's pitching well," Luhnow said. "To have a guy who's capable of pitching late in the game, in close games, we're going to have opportunity going forward. This is a team that's improving, and as the team improves, you have more save opportunities, more opportunities to pitch at the end of close games. We need more Chad Qualls. We don't need less."
