Yanks return home to face A's ace in waiting

After going 3-3 through Toronto and Chicago during last week's road trip, the Yankees should be happy to be back in the Bronx, where they've enjoyed the best home record in the American League.

But New York will face a tall task Monday as it opens a four-game set against Oakland, which will send right-hander Trevor Cahill to the mound. Cahill, 22, has vaulted into the AL Cy Young Award discussion and become the ace of baseball's youngest staff.

"It's a great experience being able to develop in the big leagues with other pitchers my age," Cahill said. "We've developed a spirit and camaraderie together. It's a great experience to be growing up with these guys."

Cahill has a 14-5 record and the league's second-best ERA at 2.43, while leading the league with his .202 batting average against. He has attributed much of his success to the addition of a curveball to his arsenal and being able to command his pitch movement.

One of Cahill's worst starts of the year came against the Yankees on July 6. He allowed six earned runs on four hits, including a pair of Alex Rodriguez home runs, over six innings to suffer the loss in a 6-1 defeat.

"That team definitely sets the bar," Cahill said after the game. "I wish I could've shown more, but it just didn't work out that way."

But Rodriguez will be unavailable to the Yankees this time around, as he is on the 15-day disabled list with a strained left calf. Mark Teixeira is also day to day after missing Sunday's contest against the White Sox with a bruised right thumb. It marked the first contest Teixeira missed due to injury all year long.

New York will counter Cahill with right-hander Dustin Moseley, who is 4-2 with a 4.63 ERA since joining the Yankees' rotation.

A's: Good reports on injured pitchers
Hurlers Joey Devine and Josh Outman, who haven't pitched all season, will join the team in Oakland for the upcoming homestand to continue their rehabs. ... Southpaw Brett Anderson, who left after two innings in Friday's start due to a hyperextended right knee, said he's ready for Wednesday's start against New York.

Yankees: Pettitte getting closer to return
Veteran left-hander Andy Pettitte is nearing his return to the mound, as he threw a successful 35-pitch bullpen session on Sunday. Pettite is 11-2 with a 2.88 ERA in 18 starts this season, but he hasn't pitched in a game since July 18 due to a strained left groin.

Worth noting
Oakland took two out of three against Texas, but still trail the first-place Rangers by 7 1/2 games in the AL West. ... The Yankees lead the season series, 5-1, and will host the A's for the first time this year.
