SAN FRANCISCO -- Having added major pieces before the Trade Deadline to contending Giants teams in the past three years, manager Bruce Bochy is aware of the potential effects on a high-profile player on an already established clubhouse.

But with the much-anticipated Hunter Pence making his Giants debut in Wednesday's game against the Mets, Bochy said the Giants' clubhouse dynamic will only benefit from a player who he repeatedly has described to be a "high-energy guy."

"He's only going to make us stronger," Bochy said.

Pence got a warm welcome from Giants players when he arrived to the clubhouse following Tuesday's 4-1 win against the Mets, and he is familiar with several players on the team, including Tim Lincecum and Ryan Theriot.

"I think chemistry is important. It's important all these guys pull together and play for the same cause," Bochy said. "That being said, winning helps chemistry. The guys are very excited about him. Anytime somebody that comes in that will help the ballclub, everybody has a better attitude."

The two-time All-Star is eligible for arbitration following the season, and Pence said he would be interested in signing a longer contract to remain with the Giants.

"Absolutely, that'd be wonderful," Pence said. "It'd be wonderful to have a home. Nobody had offered me that [with the Phillies]."

Pence differs from previous Trade Deadline acquisitions who were deemed more as "rentals" with expiring contracts, such as Carlos Beltran, who was acquired before the Deadline in 2011. Knowing Pence will be around past the end of the season, Bochy said, already allows Pence to add more to the team's chemistry.

"Across the board, the players, staff, Brian [Sabean], the front office, they're all on board," Bochy said. "That gives you a better feeling knowing that he'll be around next year."

Pence gets big welcome from Giants fans

SAN FRANCISCO -- Hunter Pence made his Giants debut in Wednesday's 2-1 loss to the Mets, receiving a thunderous standing ovation from the AT&T Park crowd when he came to bat in the bottom of the first.

"It was awesome," Pence said of the ovation. "There was a ton of energy. The fans are great out here, and it was pretty loud and crazy."

Pence popped out to Mets first baseman Ike Davis in foul territory in that at-bat and finished 0-for-4, though he did reach first base on a wild pitch after striking out in the fourth.

"We'll give him a chance to get settled in," manager Bruce Bochy said. "There's been a lot of hoopla. We're excited to have him and he'll get settled in."

Starting in right field and batting fifth, the two-time All-Star said he didn't feel himself pressing at the plate despite the adrenaline of making his Giants debut.

"I might have been trying to calm myself down too much, trying to relax too much," Pence said. "There was a lot of adrenaline, and hopefully I can get back in the flow and starting swinging the bat well."

Pence came in early before the game to scope out his new spot in right field, which has various angles on the wall and a deep right-center-field gap known as Triples Alley. He notched his first out when Jason Bay flied out to him to end the top of the first.

"It was kind of funny," Pence said. "It was really high and really slow and it almost was like time stopped for a second. It was the most routine fly ball, but with the suspense, it was funny."

The former Astros and Phillies outfielder said he has always considered AT&T Park to be his favorite road ballpark and noted that he was especially excited to get the outfield hecklers on his side after years of playing as a visiting player.

"Chicago and here are the two wildest," Pence said before the game. "There's a lot of hecklers here, and there are some pretty clever ones."

Pence also came in early to take swings in the batting cage before the team's usual stretching session and batting practice.

"He's loaded with energy. If you see him, he's always moving," Bochy said before the game. "After a long flight yesterday, he still wanted to work out, and he came in early because he wanted to take some swings in the cage."

Giants activate Sanchez, Loux from disabled list

SAN FRANCISCO -- The Giants made a pair of roster moves following Wednesday's 2-1 loss to the Mets, activating both Hector Sanchez and Shane Loux from the disabled list. In corresponding moves, the club optioned Eli Whiteside and Justin Christian to Triple-A Fresno.

Sanchez was back at AT&T Park on Wednesday after finishing a four-game rehab stint with Fresno. The rookie catcher has been out since July 17 with a sprained knee.

Manager Bruce Bochy said after the game that Sanchez will start behind the plate Thursday. Sanchez has hit .281 this season with two home runs and 24 RBIs in a backup role behind Buster Posey. Whiteside was called up to assume that role when Sanchez went down.

Loux has been sidelined since June 26 with a neck strain and has appeared in 11 games this season to post a 4.50 ERA in 16 innings.

Christian heads back to the Minors after going 6-for-37 (.167) in 21 games with the Giants, including only one hit in his last 22 at-bats.

Casilla remains in Giants' closing mix

SAN FRANCISCO -- Jeremy Affeldt notched his second of the save of the season when he closed Tuesday's 4-1 win against the Mets, but manager Bruce Bochy said he remains confident in closer Santiago Casilla, who picked up the loss in Monday' 8-7 loss against the Mets when he gave up a home run to Scott Hairston in the 10th inning.

"I really thought [Casilla] needed a day [off] last night," Bochy said. "Jeremy did a great job and we're fortunate to have a lot of guys who can do it."

After a promising start after taking over for the injured Brian Wilson in the closer's role, Casilla has struggled with a 6.89 ERA since June 1. The Giants had looked to acquire another bullpen arm before Tuesday's Trade Deadline, but no moves materialized.

"I feel good about our situation," Bochy said.
