Collins on Ike, Santana and other topics

First baseman Ike Davis is out of Saturday's lineup so utility infielder Justin Turner can get some at-bats, according to manager Terry Collins. Davis is batting just .172 and with a lefty on the hill for Arizona, it made sense to get the slumping first baseman a day off.

"We need to get the offense going so it's kind of a two-fold thing," Collins said. "I got to get Justin Turner going. I was just telling the TV guys one of the most important guys we brought up last year was Justin Turner and the job he did. You never know when something happens and he's thrown into the lineup and I got to make sure that he's getting some at-bats."

Davis went 0-for-4 Friday and rolled his ankle in the loss, but said his ankle was fine Saturday. Turner is batting just .231 with three RBIs, and only has six at-bats in the team's last 10 games. The manager believes that his first baseman is being accountable about his slump.

"I don't know if he's ever had a slump, to be honest. He got to the big leagues in less than years," Collins said. "He went through the minor leagues without having to deal with the failure and now here he is. He's facing the toughest time of his career at the major-league level. That's very difficult to do, not even talking about the media market we're in, so you know what, we grind it out here. We grind it out and get going."

IT DOESN'T MATTER: Starter Johan Santana enters Saturday's game looking for his first win of the season, despite holding a 2.25 ERA. Santana has been the victim of bad run support, with the Mets scoring 12 runs in his five starts.

While some pitchers might worry about their win-loss record, as Santana is 0-2, Collins said Santana is not caught up in his personal record. Santana has been able to keep the Mets in all but one of his starts this season.

"He's dealt in the past with no run support and knows exactly how to go about it," Collins said. "I know one thing about him, when he's out there, whether he's out there for five innings, seven innings, or nine innings, it's all effort. It's all about doing what's best for the team and that's all he talks about. All he talks about is trying to win baseball games."

OTHER NOTES: Collins said Andres Torres' 3-for-4 outing on Friday was the best game since the center fielder returned from the disabled list on April 30. … Collins went to Parnell in the seventh inning Friday instead of Ramon Ramirez because Parnell had been throwing well and was the fresher arm of the two. … Saturday is the last day Miguel Batista will be available in the bullpen before his start on Tuesday, and a pitcher will be called up Sunday. D. J. Carrasco, on a rehab assignment, is in the mix.
