By the time the San Francisco Giants eked out a run in the 12th inning, it was too late. When Tim Hudson and a half-dozen Giants relievers blanked San Diego 1-0 on Thursday, it marked the 14th shutout in 46 major league games this season. ''Out of the gate, the pitchers are really sort of dominating the league so far,'' Houston manager A.J. Hinch said. Then Trevor Bauer and the Cleveland bullpen didn't give up a Houston hit Thursday until Jed Lowrie homered with one out in the ninth.
