Pagan, Posey get rest in opener vs. Rockies

SAN FRANCISCO -- Even though he has a 10-game hitting streak to start the season, Giants center fielder Angel Pagan was absent from Friday night's lineup against the visiting Rockies, as Juan Perez made his first career start as a leadoff hitter instead.

Even though he's mindful of Pagan's hot streak, Giants manager Bruce Bochy sounded more concerned with getting Pagan a scheduled day off.

"He's really been playing well," Bochy said before Friday's 6-5 victory. "He's been out there running quite a bit. I just knew that he would need tonight or tomorrow off, and decided to go tonight."

Perez, who appeared in 34 games with San Francisco last year, said he spent most of the 2013 season in Triple-A Fresno as the leadoff man, a role he also held during the 2010 season in High-A ball. On Friday, he went 0-for-4 at the plate, but turned an eighth-inning putout into a double play by nabbing Jordan Pacheco with a sharp throw to first base.

"There's no pressure," Perez said. "Just going to go out there and do the best I can, get on base like Pagan's been doing. I don't have to put pressure. I just have to go out there and do what I know I can do."

Bochy used the same reasoning in also giving Buster Posey the night off against Colorado and starter Jorge De La Rosa, while noting that he'd like to get bench players some at-bats. In place of Posey, Hector Sanchez made his second start of the year and first one since April 3, going 0-for-3 and getting hit by a pitch.

"Well, you have to get them in there," Bochy said. "You need to mix it up and mix him in there as often as you can. It's hard to ask them to come through for you off the bench if they're not getting much playing time."

Posey was also clotheslined by Paul Goldschmidt running down the first-base line on a bunt single Thursday night. His left shoulder looked like it took the brunt of the hit from Goldschmidt before he fell to the ground, and he was also dinged up by a couple of foul balls, but the catcher said he wasn't feeling any major side effects Friday.

"I'm a little sore," Posey said. "But I don't know if it's from that [collision] or a 4 1/2-hour game."

Perez would embrace chance to pitch for Giants

SAN FRANCISCO -- Giants manager Bruce Bochy used all seven of his relief pitchers Thursday night, leaving him in quite a predicament in the late stages of the game.

Yusmeiro Petit, who also pitched two innings Wednesday, entered the series finale against Arizona in the ninth inning and finished the final two frames, but not before giving up the game-winning run in the 10th inning as the D-backs pulled off a 6-5 victory.

But if the game had gone on longer, who was Bochy's next option in line?

"There was no option," Bochy said. "He was pretty much our option. You might've seen [outfielder Juan] Perez out there, but I don't know."

As he watched Bochy mix and match his bullpen starting in the sixth inning Thursday, Perez said he gave some thought to getting on the mound.

"Earlier in the game we were joking about it. I said, 'I'm ready to pitch,'" Perez said. "I was joking. I didn't know there was a chance to go out there."

Perez, 27, hasn't logged a single inning pitching since being drafted in 2008 and it took him a moment to remember the last time he took the mound: during his college days at Western Oklahoma Community College.

Ultimately Perez didn't get to show off his arm, but said he would have embraced the opportunity.

"Not nervous," Perez said. "I would have enjoyed it, for sure."

The bullpen could be receiving a new face in the coming days as Jeremy Affeldt needed just 12 pitches to get through a perfect inning for the Class A Advanced San Jose Giants on Thursday night. Bochy said the plan is to have Affeldt throw about 35 pitches Saturday before re-evaluating the bullpen situation.

The skipper didn't rule out the scenario of having a 13-man pitching staff, meaning a reserve hitter could be on the way out when Affeldt returns.

"That's a possibility," Bochy said.

Sandoval to help choose Honorary Bat Girls

SAN FRANCISCO -- Giants fan favorite Pablo Sandoval has been named to the guest judging panel for the 2014 MLB Honorary Bat Girl program, joining Rays third baseman Evan Longoria, Braves first baseman Freddie Freeman, country music star Jason Aldean and MLB Network host Sam Ryan.

Sandoval will help choose a representative for each club in this competition, and fans can get involved by voting until April 14 at HonoraryBatGirl.com. Once the winners are selected, they will serve as bat girls on Mother's Day, May 11, or at a home game later in the month.

The league is partnering with Stand Up To Cancer and the Susan G. Komen Foundation in an effort to boost breast cancer awareness and raise research funds. Like years past, players will be using pink bats and playing gear when taking the field on Mother's Day.

For the Giants third baseman, breast cancer is an issue that hits close to home.

"When I played for the Class A San Jose Giants I lived with my host family, Donna and Ed Musgrave," Sandoval said. "They helped me with a new language, a new culture and really became my family. When we found out that Donna had cancer, we all joined together and battled as one."

The Honorary Bat Girl Program was introduced in 2009 and has since been supported by more than 4 million fan votes. Winners will be recognized in ceremonies before their respective games, receive pink MLB merchandise and two free tickets.

Worth noting

• The Giants turned a notable 4-6-3 double play Thursday night as Brandon Hicks, Brandon Crawford and Brandon Belt combined forces to retire a pair of D-backs. Hunter Pence recently discussed the abundance of Brandons on the team in a guest MLB.com blog post and second baseman Hicks said the trio of Brandons noted the novelty of their double play.

"We did a few during Spring Training and we did another last night. We talked about it a little bit," said Hicks, who started for the fourth time in six contests Friday.

• Closer Sergio Romo isn't expected to miss any time due to the stomach ailment that caused him to grimace in pain following his scoreless inning Thursday. "I'm good," Romo said before Friday's contest against Colorado.
