Giants: Chris Brock hit the Angels' Mo Vaughn with a pitch in the third inning and Tim Belcher answered by hitting Rich Aurilia with a pitch in the fourth.
Angels: Belcher made the start on three days' rest. It was originally slated for Omar Olivares, who strained his right hamstring last week.
Red Sox: Pedro Martinez's last appearance as a visiting pitcher at Olympic Stadium in Montreal was on July 4, 1993, with Los Angeles.
Pirates: Manager Gene Lamont was ejected by plate umpire Gary Cederstrom for arguing a third-strike call against Jose Guillen in the fifth.
Tigers: Detroit's Karim Garcia homered over the right-field roof May 28 against Jaime Navarro of the White Sox. Only four home runs have been hit over the more distant left-field roof at Tiger Stadium, the last by Mark McGwire on April 21, 1997.
