San Francisco Giants ace Tim Lincecum is scratched from his scheduled start Tuesday night due to inflammation in the lower left side of his back.
Giants manager Bruce Bochy hopes that Lincecum, the reigning NL Cy Young Award winner, will take his next turn in the rotation. That start could be as soon as Sunday against the Los Angeles Dodgers.
Lincecum was seen by a back specialist on Tuesday and underwent tests. The Giants recalled top pitching prospect Madison Bumgarner to make his highly anticipated major league debut Tuesday night against San Diego.
Bumgarner was the Giants' top draft pick in 2007, selected 10th overall.
