Manaea's breakout season will be cut short after going 12-9 with a 3.59 ERA in 27 starts. He struck out 108 batters and walked 32 across 160 2/3 innings. On April 22, Manaea threw the 12th no-hitter in A's franchise history against the Red Sox. It was the first no-hitter thrown in the 2018 season.
Losing Manaea deals a tough blow to Oakland as it seeks to reach the playoffs for the first time since 2014. The A's entered Tuesday trailing the Astros by three games in the American League West, and led the Mariners by 7 1/2 games for the second AL Wild Card spot.
