SAN FRANCISCO -- Matt Cain listed a litany of colors that appeared on his right forearm after getting hit by a line drive by the Pirates' Gaby Sanchez on Thursday night.
"Blue ... purple ... pink ... taupe ... lavender ... teal," he said, trying to come up with 50 shades of black and blue.
In other words, the color didn't matter nearly as much as the time he's going to miss.
Cain is making his first appearance on the disabled list in his nine years and 261 starts in the Major Leagues.
"I take pride in going out and taking the ball every fifth day," Cain said. "Not being able to do that will be a different situation."
Right-hander Yusmeiro Petit was recalled from Triple-A Fresno to take Cain's place on the roster. Giants manager Bruce Bochy said Petit probably will start Tuesday in Colorado.
"He gives us another arm and will be in the bullpen today and Saturday, if he's needed," Bochy said.
Cain will miss his first start due to injury since first donning a Giants uniform in 2005.
"As long as he's been pitching, he won't know what to do," Bochy said. "Never being on the DL before, to me, is incredible. It shows how durable he is and his toughness."
Cain was philosophical about the whole thing, saying it was a good decision to allow the arm to heal properly.
"I probably would have been pushing it to make my next start," Cain said. "If I had to wait the next couple of days, it would have been unfair to the team."
Bochy said that if the Giants were in a pennant race, he might have waited longer to see if Cain could return sooner.
"Why take a chance now?" Bochy said.
"I'll just make a new streak," Cain said.
Petit has pitched in parts of six seasons in the Major Leagues and made a start for the Giants last July. He appeared in one game earlier this year, allowing two runs over 5 1/3 innings on July 23 against the Reds.
Petit broke in with the Marlins and also has pitched for the D-backs. He owns a 10-20 overall record.
Kickham recalled to bolster pitching staff
SAN FRANCISCO -- Left-hander Mike Kickham, who made his Major League debut earlier this season with the Giants, was recalled Friday.
Giants manager Bruce Bochy said he wanted 13 pitchers available for the time being. Kickham worked four innings in Wednesday's 12-1 loss to the Boston Red Sox and is expected to be available out of the bullpen.
Nick Noonan was optioned to Triple-A Fresno to make room on the roster.
Kickham and Noonan are the only Giants players to make their Major League debuts this year.
Kickham, who is ranked as the third-best Giants prospect, was selected by San Francisco in the sixth round of the 2010 First-Year Player Draft.
Bochy rests Scutaro on Friday against Pirates
SAN FRANCISCO -- Giants infielder Marco Scutaro was not in the starting lineup Friday night and will likely be given a few more days off this season.
Scutaro has had ongoing problems with an injured finger and a sore back.
"He's a guy who will need a break during the offseason," Giants manager Bruce Bochy said. "He'll get some day games off because it is a little easier to get loose for night games."
• Left-hander Jeremy Affledt (left groin strain) will start throwing soon and could be ready to pitch by Sept. 1.
• Outfielder Angel Pagan (left hamstring surgery) will have his rehab assignment transferred to Fresno from the Arizona Rookie League. Giants manager Bruce Bochy said Pagan will play as much as possible when he returns "to get his mind right and help get him back to being the player he was."
• San Francisco pinch-hitters have 33 RBIs on the season, most in the Majors. Brandon Belt has six, while Gregor Blanco and Hector Sanchez each have five.
