Chris Heston reached 95 pitches and allowed one run in a start for Triple-A Sacramento on Monday night. Long reliever Albert Suarez showed fearlessness and good stuff in his first big-league games. Joan Gregorio, a 24-year-old righty, was promoted to Sacramento on Tuesday after posting a ridiculous WHIP (0.778) in five Double-A starts.
Tim Lincecum remains a possibility as well, although nothing is close.
The Giants thus appear to have rotation options if they decided to make a change. They are just not ready to do that.
