MILWAUKEE -- Giants manager Bruce Bochy said Monday that he has no plans to skip Tim Lincecum for a start or do something else to react to the right-hander's struggles, such as sending him briefly to the bullpen.

"He throws too well at times to make any move like that," Bochy said. "Every time he goes out there, I think he's going to have a nice game. He's so close to doing that."

Sunday's game against Oakland provided a vivid example of this. Lincecum struck out five batters in three innings before the A's scored four runs off him in the fourth inning. The two-time Cy Young Award winner fell to 2-4 while his ERA rose to 6.04.

Lincecum bore a souvenir of his fourth-inning home-plate collision with Oakland's Collin Cowgill -- a wrapped left thumb and a bandaged left wrist.

"It's precautionary more than anything else," said Lincecum, noting that his between-starts activities aren't limited in any way.

Stomach troubles sideline Pagan

MILWAUKEE -- A case of stomach flu forced Giants center fielder Angel Pagan out of the lineup for Monday night's series opener against the Milwaukee Brewers.

Manager Bruce Bochy said that Pagan didn't arrive at Miller Park until the team took the field for batting practice. At that point, Pagan went to the clubhouse to be examined by doctors, Bochy said.

Bochy pegged Pagan's playing status as day to day but expressed hope that the switch-hitter will feel fit enough to rejoin the lineup Tuesday. Pagan entered Monday with the National League's longest active hitting streak (11 games), having his safely in 31 of his last 32 games. He had started 38 of the Giants' first 41 games, all in center field.

Right fielder Nate Schierholtz replaced Pagan in the lineup, with Gregor Blanco moving from right to center. Eclipsed by Blanco, Schierholtz had started three previous games in May.
