Tim Lincecum's first loss of the year came via a debated balk call that pushed home the go-ahead run. Chris Iannetta, who replaced the injured Troy Tulowitzki in the first, scored on that seventh-inning balk by Lincecum that led the Colorado Rockies past the San Francisco Giants 3-2 on Tuesday night.
Iannetta also hit the first home run off Lincecum this year with a second-inning solo shot to help Aaron Cook (4-1) win his fourth straight start. Iannetta doubled to start the seventh. Giants manager Bruce Bochy was ejected for arguing the balk, a night after Rockies skipper Clint Hurdle was thrown out for the same thing. Lincecum (4-1) allowed Iannetta's solo home run, but was efficient and got many quick outs the rest of the way.
