OAK@SEA: Kazmir Ks nine, walks none over six innings

ANAHEIM -- Manager Bob Melvin said Monday that the entire A's rotation will have its next start pushed back a day, thanks to Thursday's off-day.

Left-hander Scott Kazmir, who pitched six shutout innings Sunday in Seattle in his latest gem for Oakland, would probably benefit most, since he left that one early because of triceps tightness.

Melvin, who was managing the Mariners when Kazmir made his Major League debut Aug. 23, 2004, with five shutout innings in a Rays victory, said he couldn't recall a pitcher who's come back so well from a shoulder injury, as Kazmir has.

"He threw 95 [mph] yesterday," Melvin said. "He was dominating. I know he's having a lot of fun, and he's fit in well on this club."

Released by the Angels on June 15, 2011, Kazmir went to independent ball the next year to fight his way back, and had a good year with Cleveland in 2013

"I was in the other side, when he had his first game," Melvin said, remembering the kid -- now 30 -- who just rocked and fired. "He was in the low-to-mid 90s then.

"He's had to reinvent himself since then. It's hard to see the ball from him."

Gentry steps in for Crisp, who has tight hamstring

OAK@SEA: Crisp steals second for his third of season

ANAHEIM -- Craig Gentry started in center field Monday night for the A's in place of Coco Crisp, a switch that was planned Sunday after Crisp experienced left hamstring tightness in Seattle.

"It's a little tight," manager Bob Melvin said of Crisp's hamstring before the series opener at Angel Stadium. "He is going to take BP and run around a little. He's literally day to day, at this point."

Crisp just returned to action Friday after missing three games at Minnesota because of a wrist injury.

"He felt a lot better yesterday [on that count]," the manager said. "If he takes a good BP today, I think we're clear of that."

As for Gentry leading off, Melvin said, "On this team, whoever plays center field," noting that's Crisp role, and one filled by Sam Fuld before he was designated for assignment.

Gentry, a former Ranger, "has been a guy who's done well against left-handed pitchers," and him leading off "is based on what he does on the basepaths."

Worth noting

• Red-hot Alberto Callaspo, the ex-Angel, remained in the A's lineup for a seventh consecutive start Monday, this time as the DH against left-hander Hector Santiago. Callaspo entered hitting .345 overall, and .400 in his starting streak.

A's hitting instructor Chili Davis, asked if he's changed the switch-hitting infielder any since Callaspo was traded to the A's on July 30 for infielder Grant Green, said not much at all.

"Oh, I get on him to stay in that squat he hits from, and don't come up out of it like he's a big guy," Davis said. "He knows what he should be working on. And he works. He doesn't over-work. He works right. And, he's fun to have on this team."

• Nick Punto, who gave shortstop Jed Lowrie his first day off Sunday, started at second base against the Angels on Monday.
