RHP Chase Anderson finished his year on a good note, tossing 5 1/3 innings of one-run ball as the Diamondbacks beat the Colorado Rockies 3-1 on Wednesday night at Chase Field.

The bullpen combined to throw shutout ball over the final 3 2/3 innings, the second night in a row the relievers pitched well, as the Diamondbacks improved to 12-6 against the Rockies this season.

Finishing strong: With Wednesday’s outing, Anderson turned in back-to-back solid performances to end his year, an encouraging development for a pitcher who struggled for much of the summer.

Anderson, who struck out a career-high 10 in his previous outing, said he didn’t feel particularly sharp, but he managed to hold the Rockies in check and work into the sixth inning.

“I just wanted to finish strong,” he said. “The last one was really good and this one was just a battle but we won the game. I feel good about where I’m at right now. That’s a lasting impression and hopefully it can be a good thing.”

Assuming he doesn’t pitch again in the final four games, Anderson will finish with a 4.30 ERA in 152 2/3 innings.
