ST. LOUIS -- Ryan Sadowski's not going anywhere for the immediate future. Including Japan.

Giants manager Bruce Bochy indicated Monday that Sadowski, who excelled Sunday by working six shutout innings at Milwaukee in his first Major League start, would remain in the rotation until further notice. The right-hander's next scheduled turn will be Friday night's homestand opener against Houston.

"Right now, the plan is to give him another start," Bochy said, then quickly amended his remark. "I don't want to leave it as a start at a time. He's in the rotation."

The Giants will face an intriguing decision come Friday, when infielder Rich Aurilia comes off the bereavement list. Since Aurilia's absence leaves the Giants' active roster one position player short of their usual complement, they'll likely have to drop a pitcher, and nobody's throwing poorly enough to warrant a demotion -- with the possible exception of Jonathan Sanchez, who Sadowski replaced in the rotation and has an option left.

The Giants should feel fortunate that they had Sadowski to summon when they decided to replace Sanchez. A little less than two weeks ago, the Yokohama Baystars approached Giants management about obtaining Sadowski.

"They were just exploring options," said Giants vice president of baseball operations Bobby Evans.

Sadowski said that he heard of the Japan feeler only indirectly. When a reporter observed that pitching there might have seemed different, Sadowski said, "This is different, too. Six years playing in front of small crowds [in the Minor Leagues]; all of a sudden, you're playing in front of a sellout crowd in Milwaukee."

Sadowski noted that his sudden success won't prompt him to alter his pitching routine.

"I'm not going to change, whether I throw here or [Triple-A] Fresno, or whether it would have been Japan," he said.

One aspect of life that Sadowski did change was his text-message plan on his cellular phone account. He said he received 50 text messages in the wake of his first big league victory in the Giants' 7-0 decision at Milwaukee.

"I usually get five a month," he said.
