"It's a good arm," manager Jim Tracy said. "It's a hard 96 [mph], down. That's tough to hit."
Scahill entered Tuesday's game in the ninth with the Rockies trailing, 9-6, and on their way to a 9-8 loss. He said the wait for his Major League debut "wasn't that agonizing" because he realized Tracy wanted to put him in a situation that would benefit Scahill.
"I was able to spot my fastball pretty good," said Scahill, who threw 13 of his 22 pitches for strikes. "My curveball was pretty good. I yanked a couple sliders and I just kind of put that on the shelf. I went a little deeper in counts than I would've liked, but that'll happen."
