Arrieta was dominant on Sunday night against the Dodgers, striking out 12 and allowing just two batters to reach base. One Dodger reached on a walk, and the other on an error. He became the first pitcher to strike out the side in the ninth inning of a no-hitter since Sandy Koufax in 1965.
The 29-year-old Arrieta became just the seventh pitcher in big league history to throw a no-hitter in the same season as being on the losing end of an opponent's no-hitter. Arrieta lost to Cole Hamels on July 25, when the former Phils ace no-hit the Cubs at Wrigley.
This was the second weekly honor of the season for Arrieta, who also won the award for the week ending July 12. Entering Monday's action, he led all Senior Circuit pitchers in victories (17), complete games (three) and shutouts (two), while riding a streak of 14 straight quality starts.
