PHOENIX (AP) -- Tim Lincecum had a rough spring training debut against major league hitters.
Lincecum was San Francisco's first-round selection in last year's amateur draft.
He gave up three runs in two innings of work today, as the Giants beat the Milwaukee Brewers 15-6 in a split-squad game in Phoenix.
Lincecum gave up three runs in the first inning and threw a wild pitch.
In the second, he struck out the bottom two batters in the Brewers' order - shortstop Yohannis Perez and starting pitcher Dave Bush.
Bush also struggled in his second start of spring training, giving up four runs and five hits in two innings.
He struck out five and walked one.
Milwaukee's Bill Hall hit his second homer of spring training and also made several nice plays while attempting to learn his new position in center field.
Johnny Estrada and Mat Gamel had two RBIs each for the Brewers.
Estrada is hitting .562 with 10 RBIs in six games.
