OAK@HOU: Kazmir fans seven in six innings of work

OAKLAND -- A's starters Jesse Chavez and Scott Kazmir, both of whom went unbeaten in April, were among those in contention for American League Pitcher of the Month, an award that went to Oakland ace Sonny Gray on Monday.

Kazmir, who won a combined 10 games in the Majors over his previous three seasons, entered his Monday night start against the Mariners 4-0 with a 2.11 ERA.

"He's great," Gray said. "He's great to everyone on the staff. He's really supportive, a good teammate and a good friend. When you come here, you are expected to perform well, and that's our expectation as a team. As a staff, we try to outdo one another. It's a good group, full of energy."

Chavez started two games for the Toronto Blue Jays in 2012, his only starts in 191 Major League games entering the season. He pitched out of the A's bullpen last year, but when Jarrod Parker and A.J. Griffin were lost for the season to Tommy John surgery, Chavez was stretched out as a starter in Spring Training.

"It's just the opportunity, a consistent opportunity," A's manager Bob Melvin said. "He's prepared himself for this opportunity. It's a pretty unique story."

The 30-year-old veteran is 2-0 in six starts with a 1.89 ERA.

OAK@BOS: Reddick leaves the game after twisting ankle

OAKLAND -- A's outfielder Josh Reddick, who suffered a sprained left ankle in Sunday's 3-2 win at the Boston Red Sox, will take at least two days off to rest his injury.

Oakland manager Bob Melvin said he thought it was also wise that fellow outfielder Yoenis Cespedes take a day off after appearing to favor a sore leg in beating out an infield single, plating the go-ahead run, Sunday in Boston.

"He wanted to play, but the way he came out of the box made me feel he needed to take a day," Melvin said of Cespedes. "He is available off the bench."
