Although the A's clinched their second straight American League West title earlier this week, they're still one game behind the Red Sox in the fight for the top seed in the AL and home-field advantage in the playoffs.
Dan Straily, who has won his past four decisions, will take the mound for Oakland. In four starts this month, he's 3-0 with a 2.31 ERA and 21 strikeouts in 23 1/3 innings. However, Straily owns an 0-2 record with a 7.31 ERA in three starts against the Angels this season.
"You see their aggressiveness all over the baseball field," Straily said after a recent start. "Some days it can help you and some days it can really hurt you. You just try to match their aggressiveness and hopefully come out on top."
The Angels have an opportunity to go 9-0-1 in their last 10 series with a win on Wednesday. Jered Weaver will take the mound after being scratched from his start on Friday. The ace experienced tightness in his right forearm, and doesn't anticipate any troubles as the Angels close their home schedule.
"I didn't want people to think that I was just packing it in because it's the end of the season," Weaver said. "We still have a job to do. If I was feeling healthy, I'd be out there. But like I said, it's something that's been kind of lingering, and I just wanted to make sure [Angels manager Mike Scioscia] knew about it and see how he wanted to go about it. I'm excited to go out there and make that last start on Wednesday."
Weaver has won three of his past four decisions and is 7-3 with a 3.14 ERA and 1.09 WHIP since the All-Star break, striking out 65 in 80 1/3 innings.
Angels: Williams set to start on Thursday
Jerome Williams was hit in the foot with a ball on Monday and is set to start on Thursday, although Scioscia did leave the door open.
"He's still on board to start on Thursday," Scioscia said. "But we'll see."
Williams was playing catch with Dane De La Rosa and a throw hit his left foot. Williams was "hobbling a little" on Monday but was doing better Tuesday.
Athletics: Freiman may not be ready for postseason
Nate Freiman took part in tee work and soft toss on Tuesday afternoon, moving a step closer to returning from an abdominal strain, but his chances of earning a spot on the A's playoff roster remain low.
Catcher Derek Norris has been taking grounders at first base to prepare to fill the potential void.
"I hope he doesn't have to factor in that position," manager Bob Melvin said. "It was just based on the fact that Nate is not active for us right now. Just having someone else take some ground balls."
• The Angels (38-42) will finish with a home record below .500 for the first time since 2001.
• Weaver has dominated Coco Crisp, holding him to a .146 batting average in 48 career at-bats and striking him out 10 times.
