Whether it's on the mound or at the plate, Oakland has come to play, tossing three quality starts to win each game by a slim one-run margin.
"They've done a really good job. You look at it, they're all a little bit different," Girardi said of the A's rotation. "They're young, they're throwing the ball well and they're locating."
The Yankees will try to reverse their fortune come Sunday as the team tries to prevent a four-game sweep.
Having a tough time getting runners on base in the series, New York has managed just one walk through three games. The team was unable to draw a walk in the first two games, marking the first time it had gone consecutive contests without a free pass since September of last year.
That could be a problem for the Yankees again on Sunday with Bartolo Colon set to take the hill. With pinpoint control for much of the season, Colon has surrendered just two walks in his last four games.
He allowed just one walk in his last start against the Rangers on Tuesday, but took the loss after allowing four runs on eight hits in seven innings of work.
"Bart's another one of those guys, he's not going to walk people. He's not. He's coming right at you. 'Here it is, I'm going to throw it, I'm going to locate it down and away and inside with movement,'" Girardi said of his former pitcher. "'If you do something with it, do something with it.'"
A veteran workhorse for Oakland this season, the right-hander has a 2.89 ERA over his last seven starts.
"We felt like with the youth that we were going to have in our rotation, his experience and all that he's been through and the way he goes about his business and prepares, would be good for our younger guys," said A's manager Bob Melvin.
Yankees: Sabathia takes hill after 32nd birthday
After turning 32 on Saturday, CC Sabathia will get the start for the Yankees in Sunday's series finale.
If the left-hander can get the win, it would mark his 11th win, a mark he's reached in his first 12 seasons in the Majors. He'd then join Don Sutton, Eddie Plank and Tom Seaver as the only pitchers to accomplish such a feat in the modern era.
Sabathia got the victory on Tuesday against the Blue Jays, tossing six scoreless innings and allowing only four hits and one walk in his return from the disabled list.
In his last nine starts against Oakland, Sabathia is 6-1 with a 2.62 ERA.
A's: Cespedes on a roll
On a tear as of late, Yoenis Cespedes continues to show few growing pains in his rookie campaign.
Over his last nine games, Cespedes is hitting .576 (19-for-33) with four home runs.
"The ball gets up there in a hurry and it can make you do some funny things, even though you try to have a plan each and every time," Melvin said. "But I think the confidence that he has going the other way and up the middle is lending him to feel pretty confident about having a particular plan and staying with it."
Josh Reddick was at designated hitter on Saturday instead of his normal right field position in an attempt to help give him some rest, according to Melvin. Brandon Moss took Reddick's spot in right and Chris Carter started at first base.
A's right-hander Brandon McCarthy, on the 15-day disabled list since June 20 with recurring shoulder soreness, threw another bullpen session on Saturday and said it went well. Melvin said the team would wait until Sunday to determine McCarthy's next step.
Yankees right-hander Joba Chamberlain's next rehab game will likely come Tuesday, with the Class A Advanced Tampa Yankees for a second straight outing. Chamberlain's made four rehab appearances so far, and his first above rookie ball came on Friday when he made a two-inning start for Tampa in Bradenton, Fla. He gave up a home run to the first batter he faced, the only run he allowed.
