Crisp sits out again with strained left groin

OAKLAND -- Outfielder Coco Crisp was not in the starting lineup for a second straight day due to a strained left groin.

He appeared in good spirits in the clubhouse Sunday, and A's manager Bob Melvin was looking forward to watching him during batting practice.

"We'll have a better indication of where he is after batting practice," Melvin said.

Meanwhile, infielder Adam Rosales is getting closer to a rehab assignment.

Rosales took batting practice the past two days and needs to clear one final hurdle as he recovers from a strained left intercostal.

"He needs to turn the double play and make an aggressive throw," Melvin said. "That's how he hurt it in the first place."

Taylor bringing new mindset as he rejoins A's

OAKLAND -- Michael Taylor received some advanced warning that he might be needed in Oakland. He learned of Yoenis Cespedes' injury late Friday night after the Triple-A Sacramento River Cats played a game in Reno.

He was on a plane to the Bay Area early Saturday morning, arriving about 90 minutes before Saturday's game against the Detroit Tigers.

Taylor has played for the A's briefly in each of the past two seasons with mixed results. This time around, another year older, he's learned to be patient with himself.

"I have a process I trust and have been successful," Taylor said before the A's took on the Tigers in Sunday's series finale. "There's not a lot of anxiety any more. I go about my day and make tweaks and strides."

Taylor said he used to wonder why he couldn't go 4-for-4 or have the perfect swing all the time. That led to anxious moments and added pressure. It was not an ideal situation.

He has appeared in 17 Major League games and has 51 official at bats. Taylor has hit one home run, also his only RBI. He has struck out 21 times.

Taylor was hitting .410 with the River Cats when he was called up.

"You do your early work, you stay in a routine and you don't get lazy," Taylor said of his hot start with Sacramento. "Sometimes, when things are going good, you might decide to take a day off. I remind myself to stay focused and once the game starts, enjoy it."

A's manager Bob Melvin said he's trying to find a start for Taylor.

"He's been here a few times and he's comfortable in this clubhouse," Melvin said. "He knows to stay ready once the game starts."

Worth noting

• It happened on this day: In 1971, Reggie Jackson hit his 100th home run as an Athletic to become the first Oakland player to reach that plateau. In '74, Jim "Catfish" Hunter recorded his 1,000th strikeout, the first Oakland pitcher to reach that level. In '76, Vida Blue recorded his 1,000th strikeout.

• In 2001, Miguel Tejada hit the 10,000th home run in Athletics franchise history.

• Infielder Jed Lowrie, who turns 29 Wednesday, made his eighth career appearance batting fourth, the second this season.

• Right-hander Pat Neshek pitched 2 1/3 innings in Saturday's loss to the Tigers, the longest relief appearance of the season by an A's pitcher.

• The A's bullpen has allowed one earned run or fewer in 11 of the first 12 games.
