PITTSBURGH (AP) – Unbeaten Shane Bieber racked up 11 more strikeouts and combined with four relievers on a seven-hitter Thursday night as the Cleveland Indians blanked the Pittsburgh Pirates 2-0 to win their sixth in a row and sweep the three-game series. The right-hander scattered six hits and did not walk a batter in six innings before being lifted after his pitch count reached 99. Bieber raised his season strikeout total to a major league-best 65 in 40 2/3 innings, an average of 14.4 per nine innings. Oliver Perez, Nick Wittgren, James Karinchak and Brad Hand finished the shutout.
