Eli throws out first pitch at Citi Field

NEW YORK -- Eli Manning only had to throw one 20-yard pass this Sunday, but he wasn't using a football. The Giants' quarterback made his first trip to Citi Field to throw out the ceremonial first pitch on Father's Day with his daughter, Ava.

"It's a special day," Manning said. "I'm happy to be here on behalf of Pampers, celebrating Father's Day and honoring all fathers. It'll be a fun day with Ava on Father's Day."

Manning warmed up his arm in the bullpen before the game, but had to alter his motion, as he threw the pitch with his 1-year-old daughter in his arms. He said, as much as he wanted to, he couldn't bring the gas.

"I'd like to get on the mound, toe the rubber and whip it down there," Manning said. "But I don't think I'll be doing that today.

Manning talked to a few players before the game, visiting the Mets' clubhouse before the team wrapped up its series with the Reds. He played second base in high school, but never pitched.

"It's a little different locker-room mentality for baseball and football," Manning said. "We get 16 games, and they get 162. But all the players and coaches were real nice."

Manning considers himself a New York baseball fan, and supports both the Mets and Yankees, but he knows there's one easy way to lose the approval of New York.

"I know you can't one hop it down there, so if I miss, I'll miss high," Manning said.

Manning lobbed his pitch straight into the glove of Mets third baseman David Wright.

Collins believes bats will heat up with weather

NEW YORK -- Mets manager Terry Collins believes that warmer weather will help jump-start New York's offense, which scored only four combined runs in the opening two games against the Reds.

"We saw it last time we were home," Collins said. "When the weather starts to warm up, the ball's going to carry a lot better here, so it'll play differently."

Collins said he was surprised that deep balls off the bats of David Wright and Ike Davis on Saturday went for outs, and he believes that moderate air temperatures have kept more balls in the yard at Citi Field.

"That cool air just knocked them down, but when it starts to heat up, you're going to see a difference in how the park plays."

The Mets rank 11th in the National League with 53 home runs entering Sunday, 26 of which have been hit at Citi Field.

Quintanilla moves up to No. 2 spot in order

NEW YORK -- Omar Quintanilla batted second in the Mets' lineup on Sunday, his highest spot in the batting order this season.

Entering Sunday, Quintanilla was batting .288 (15-for-52) with four RBIs. He also had a .393 on-base percentage, with seven walks.

"He's been very patient at the plate," manager Terry Collins said on Sunday morning. "He's handled himself well. I think he's more disciplined at the plate than he has been in the past.

"He gets on, he takes his base on balls, he's not chasing out of the zone. So we looked at those things today, and we said we've got to start getting some guys on for the middle of the lineup."

Collins said Quintanilla's recent success -- he had just one hit in 22 at-bats last season with the Rangers -- has come as a result of working with Mets hitting coach Dave Hudgens.

"Because I've never seen him in the past and never saw him play in the past, I really can't tell you what difference he's making," Collins said. "All I know right here is that he's handling himself, and when he gets balls to hit, he's putting good swings on them."

Worth noting

• Ruben Tejada is set to begin a rehab assignment at Triple-A Buffalo on Monday, according to Collins. Tejada had previously been rehabbing with Buffalo, but pulled himself from a game on June 5 after experiencing an issue with his injured right quadriceps.
