SAN FRANCISCO -- Chad Gaudin is in worse shape than expected after taking a line drive off his pitching forearm on Thursday.
"He's a little more sore than we were hoping yesterday," manager Bruce Bochy said. "To be honest, he's a bit of a question mark."
Bochy said he planned to meet with general manager Brian Sabean and head athletic trainer David Groeschner before Sunday's game to make a decision about Gaudin, whose next turn in the rotation falls on Tuesday in Game 2 of the L.A. series against Dodgers righty Stephen Fife (1-2, 3.25 ERA).
"We'll have to make a move if he can't make a start," Bochy said. "It would be (Mike) Kickham's turn if we need a starter for that day."
Gaudin, 30, didn't take his scheduled bullpen session on Saturday, and it was again unclear if he would test the arm on Sunday. But Bochy said it's possible Gaudin makes his start without throwing a bullpen. Since being moved into the starting rotation, Gaudin owns a 3.38 ERA over 21 1/3 innings.
Kickham, 24, made a spot start for the Giants against the A's on May 28, lasting 2 1/3 innings and allowing four runs in a 6-3 loss before he was sent back down.
Angel Pagan says he wants to do the best thing for his body, which a Los Angeles doctor will hep decide when the Giants center fielder brings his MRI results for a second opinion on Monday.
The news Saturday was a new small tear in Pagan's left hamstring, which he suffered while running to first in his Single-A rehab debut on Thursday. He was carted off the field.
"I've tried two things already," Pagan said Sunday, referring to the cortisone shot and platelet-rich plasma (PRP) injection he received. "Pretty much the only options. But I want to see what (the L.A. doctor) has to say.
"I'm pretty optimistic that there's a good option for me. I'm just hoping for the best so I can get this problem taken care of and get back to playing as soon as possible."
Pagan, 31, is batting .262 with three home runs and 24 RBI for the Giants this year, though he has missed the last 25 games since his inside-the-park, walk-off home run on May 25.
Pagan said he contacted former teammate, friend and hamstring-rehabber Jose Reyes for advice.
"He helped me out, going through this process," said Pagan, after revealing that he is dealing with significant pain every day. "The PRP, which I did. He went through the same injury, so we were trying to see any advice that he got."
Reyes completely tore the hamstring tendon behind his right knee in 2009 and had surgery to repair it and get him back to game shape. Pagan could be following in his friend's footsteps, and we should know more after Monday's meeting.
The Giants bullpen could use a fresh arm, and they have one in Santiago Casilla, who continues to rehab from surgery to remove a cyst from his knee.
"He's really coming along well," Bochy said. "He feels great. He's really excited about how his knee feels."
The Giants bullpen has missed its regular eighth-inning setup man, going 1-5 with a 3.86 ERA in June while converting only four of nine save opportunities.
Casilla, who threw a side session at AT&T Park on Sunday, is expected to face live hitters while the team is in Los Angeles and make at least two rehab assignments before he rejoins the team.
"He has a chance to join the team by the end of the road trip," Bochy said.
The Giants finish the 10-game, three-city road trip against the Reds in a four-game series from July 1-4.
Barry Zito completed seven innings on Saturday, but the Giants still taxed their bullpen with 1 2/3 innings each from Sergio Romo and Sandy Rosario.
Romo needed just 20 pitches to do it, and Bochy said he is available Sunday. But the manager would like to stay away from Rosario, who expended 34 pitches to get his second win of the season.
Bochy said he's never seen so many fan interferences in a season before, and we are still 21 games away from the All-Star break, though he's not faulting the fans.
"If I'm a fan, my first reaction is to go for that ball," Bochy said. "I want it, too."
