On Tuesday, he replaced an ineffective Juan Nicasio and went 2 1/3 innings, giving up two runs on a Matt Holliday home run. But Scahill, in his first year as a full-time reliever, has pitched scoreless ball in all but five of his appearances and has a 4.60 ERA. At Triple-A Colorado Springs, he went 5-1 with a 4.50 ERA in 23 games covering 46 innings.
The key stat for him was he struck out 45 against 11 walks -- 2.2 walks per nine innings. Last season in Triple-A, when starting all 29 of his appearances, he finished with 159 strikeouts against 74 walks -- 4.4 walks per nine. The improved control could earn him some middle innings for the Rockies, who use their bullpen extensively and need dependable relief when a starter exits.
"I just want to try to leave an impression for next year," Scahill said. "I'm throwing strikes. That was one of the things I'd struggled with in the Minor Leagues, being consistent in the strike zone. That's something I worked very hard on. I feel I've been successful.
"Before, I just had bad misses. I wanted to eliminate completely worthless pitches. Every pitch should have a purpose."
