The Guardians beat the D-backs 5-0 on August 2, answering back after Arizona had been climbing fast.
Gavin Williams set the tone with 5.2 scoreless innings, 10 strikeouts, and just one hit allowed.
Patrick Bailey homered in the third, and Chase DeLauter added the big swing with a two-run double in the fifth.
What It Means
Cleveland moved back toward the middle of the race, while Arizona lost some of the separation it had built.
BaseChaser now has the Guardians at 48.8%, with the D-backs at 52.5%.
That keeps both teams in the messy part of the board, where one clean win can change the race quickly.
