Maeda improved to 15-9 after allowing one run on three hits and three walks with six strikeouts in five innings during a 3-2 win over the Diamondbacks on Friday.
Pitching on four days' rest for only the second time in the second half, Maeda needed 94 pitches to get through five innings. He was effective, however, keeping a dangerous lineup at bay and outdueling Zack Greinke in the process. The 28-year-old rookie has settled into a groove during the second half, going 7-2 over his last 10 starts without allowing more than three earned runs in any outing. Maeda will look to keep rolling in Wednesday's home start against the scuffling Giants.
