SAN FRANCISCO -- Left fielder Melky Cabrera is not in Saturday's lineup against the Texas Rangers and is likely to miss the entire weekend series because of a tender left hamstring, Giants manager Bruce Bochy acknowledged.
"There's a good chance of that," Bochy said. "He could show up tomorrow andbe ready to go. But were always leaning (on the side of caution). We feel thats the way to gowith these guys. You dont want a setback and to lose him for an extendedperiod. Well wait till hes ready."
Cabrera felt his hamstring grab while stealing a base in the seventh inning Thursday at San Diego. Until missing Friday's game, he was the only Giant who had played every day this season, starting all but once.
He leads the NL with a .364 average, 87 hits and seven triples.
Nate Schierholtz continues to start in right field, with Gregor Blanco shifting to left.
In other pregame news, the Giants optioned right-hander Steve Edlefsen and called up right-hander George Kontos, whom the club acquired at the end of the spring from the New York Yankees in exchange for catcher Chris Stewart.
Kontos was 2-0 with a 1.71 ERA in 23 games for Fresno. He is coming off four scoreless outings, and two of them were two-inning affairs. It's his ability to go multiple innings that made him a favorable choice; Edlefsen is struggling, but the Giants need innings and length with several members of the 'pen still nicked up.
I am compelled to point out that Kontos is a Northwestern University alum. So I finally have someone who will listen when I prattle on about Wildcats football.
Sergio Romo is expected to be available today, Bochy said.
