Joe Girardi said he still believes in Chasen Shreve, despite the lefthander's recent struggles.

Brian Cashman didn't sound quite as sure.

"I don't have any concern about his health, but he's obviously pitching in a poor stretch right now," Cashman said before Saturday afternoon's game, a 5-0 Yankees victory. "That [may] give opportunities elsewhere in leverage situations until we can get him through it. Shreve is one of the reasons we got this far. But Joe at times may obviously need to call a different name until we can get him resuscitated."

Shreve entered Saturday with a 10.80 ERA in his previous games, raising his ERA from to 2.67 from 1.86 in that stretch. With the Yankees trailing by a run in Friday night's seventh inning, the lefthander allowed a two-run homer to pinch-hitter Juan Uribe.

But Girardi said even with those difficulties, Shreve is in the quartet of bullpen stalwarts he trusts, a group that includes Justin Wilson, Dellin Betances and closer Andrew Miller.

"I still have a lot of belief in Shreve," Girardi said. "I know he's had struggles recently, but this guy has pitched really well for us this year. You look at his body of work [for the season] not necessarily a snapshot of time. We need his innings. He's our guy and we believe he'll turn it around."

CC bracing for success

CC Sabathia comes into Sunday's start having allowed one earned run in his previous two starts, comprising 111/3 innings. The 35-year-old looks the best he has all season in large part, he said, because of the brace he's been wearing on his left knee since coming off the DL.

"It's helped a lot," Sabathia said. "The brace lets me let it go and I don't have to worry about swelling. Just giving me the confidence to get on my front side and let the ball go."

Ackley earning time

Dustin Ackley got the start at second base Saturday and before going 1-for-3 with a triple, Girardi said the trade deadline acquisition was in line for some more playing time.

"We really like the way he's swinging the bat," Girardi said. "That's big reason we're putting him in there. The hope is he does some damage."

Ackley, seven for his last 13 after Saturday, led off the fifth with a triple to center but was stranded as Noah Syndergaard retired three straight.

Extra bases

Girardi said he had not yet made a decision on Masahiro Tanaka, who started Friday, pitching Wednesday in Toronto, which would make it three straight starts on four days' rest. "We'll see how he feels tomorrow," Girardi said. "That's the original plan." . . . Brian McCanns two-run homer in the sixth was his 26th home r of the season, and first since Sept. 6, a total that leads all catchers.
