Lance Lynn pitched neatly into the eighth inning before leaving with ankle injury that's not considered serious, beating San Francisco for the first time in his career as the St. Louis Cardinals blanked the Giants 6-0 on Saturday.
Lynn (11-8) awkwardly came off the mound to field Juan Perez's leadoff chopper in the eighth and twisted his right ankle trying to throw to first. That was Lynn's final batter, and he exited with a mild ankle sprain that will be reevaluated Sunday.
Lynn gave up six hits, struck out two and walked two. He had been 0-4 with a 6.33 ERA in his previous four regular-season starts against San Francisco and 0-1 in three postseason outings.
