PITTSBURGH (AP) — Andrew Heaney carried a no-hitter into the sixth inning and Spencer Horwitz powered Pittsburgh’s offense as the Pirates cruised past the St. Louis Cardinals 7-0 to match a season high with their fourth straight victory. Heaney allowed three hits and struck out seven on 95 pitches through 6 2/3 innings. After a 71-minute rain delay, he walked Brendan Donovan to start the game before retiring the next 16 batters. Victor Scott II spoiled the no-hit bid with a two-out single in the sixth. The last-place Pirates have outscored their past four opponents 37-4, including a lopsided three-game sweep of the Mets over the weekend. Horwitz hit a leadoff homer against Erick Fedde and finished with three RBIs.
