PITTSBURGH -- Andrew McCutchen clubbed his 15th homer of the season and the Pittsburgh Pirates completed a doubleheader sweep of the St. Louis Cardinals with 6-0 victory on Tuesday night.
Brandon Cumpton (1-1) allowed three hits over seven innings to pick up his first major league win. The sweep propelled the Pirates into first place in the NL Central. Pittsburgh is a season-high 22 games over .500 (64-42).
Tyler Lyons (2-4) gave up four runs, three earned, in six innings. The rookie struck out five and walked one but received no help from a reeling offense. The Cardinals have dropped six straight and have scored five runs in their last 56 innings.
St. Louis catcher Yadier Molina left in the fourth inning with a right knee strain.
