LOS ANGELES -- Feeling ill as he did during part of Spring Training, right-hander Tim Lincecum returned to San Francisco on Thursday morning for a medical examination, Giants manager Bruce Bochy said.

Bochy relayed that doctors found nothing unusually wrong with Lincecum, who's expected to make his next scheduled start Saturday against Arizona.

"That's why we sent him back, to take away any concerns," Bochy said, noting that Lincecum began feeling "queasy" on Wednesday.

Lincecum's progress in Spring Training was briefly delayed by a case of bronchitis. But last year's National League Cy Young Award winner has not used that as an excuse for his slow start. Lincecum's 0-1 with a 7.56 ERA after two outings.

"He has been a little sickly the last couple of months," Bochy said, adding that the bronchitis "zapped him a little bit."
