Shane Bieber kept up his record strikeout run, fanning 13 and pitching the Cleveland Indians past the Cincinnati Reds 6-3 on Sunday.

Bieber (2-1) became the first pitcher in big league history to begin the season with four straight starts with at least 10 strikeouts.

The AL Cy Young Award winner has 48 strikeouts this year, matching Hall of Famer Nolan Ryan for the most through the first four starts of a season. Bieber has fanned at least eight in a 16 straight starts, one short of Randy Johnson’s major league mark.

“I felt a little slow, a little sluggish at the beginning of the game but was able to get through it and kind of get on a roll there at the end,” Bieber said.

Bieber struck out the side in the seventh. He wrapped up his outing by fanning three more in the eighth around a solo home run by former teammate Tyler Naquin.

The Indians hit three home runs, all with two outs, to salvage a win in the all-Ohio series.

Roberto Pérez hit a three-run homer off Wade Miley (2-1) over the center field wall with two on in the fourth inning for a 4-0 lead.

José Ramírez launched a solo drive into the upper deck in the first. Jordan Luplow had a two-run homer in the seventh.
