Shane Bieber lowered his ERA to 1.63 in his final regular-season start — the lowest in the American League since Luis Tiant's 1.60 for Cleveland in 1968 — and Jordan Luplow hit a game-ending home run that gave the Indians a 3-2 win over Chicago on Wednesday night.
Bieber, who leads the big leagues with eight wins, allowed an unearned run and two hits in five innings with 10 strikeouts in his eighth double-digit strikeout game, also a major league high.
"I'm not going to get caught up in that stuff, but what I'm proudest of is the consistency," Bieber said. "You wait your whole life to pitch in games like this. It's a lot of fun right now.
"I'm beyond excited to have the opportunity to do what I'm going to be able to do over the next week."
With the score 2-2, Luplow homered onto the porch in left field off Gio Gonzalez. A .194 hitter, Luplow struck out in his first three at-bats before he hit his second home run this season.
"I was trying to be aggressive and get a good pitch to hit," Luplow said. "I just treated it the same as in any other situation."
Lucas Giolito gave up two runs and four hits in six innings, throwing a career-high 119 pitches.
