Twins manager Ron Gardenhire liked what he saw of Nick Blackburn last year when he was 11-11 with a 4.05 ERA as a rookie starting pitcher.
But Gardenhire thinks the 27-year-old righthander, who beat the Pirates 5-1 Thursday at the Metrodome, has taken another step forward.
"Blackie was pretty good last year, and I think we saw at end of the year how much he had grown as a pitcher," Gardenhire said. "His ball is really sinking now, he has lot of confidence; he's mastering the strike zone, he's using all of his pitches.
"[He has] a four-pitch mix, and right now he's rolling along as good as anybody on our staff. You need that, you need guys like that to go out and shut people down, and he did that."
Blackburn pitched a six-hitter for the Twins' first complete game of the season.
Pitching coach Rick Anderson said Blackburn's sinker is now his "out" pitch.
"He just keeps improving each times he goes out," Anderson said. "[He is] just being able to slow himself down and think about executing his pitches, instead of trying to throw as hard as he can."
Anderson believes Blackburn, who is 6-2 with a 3.09 ERA, is comfortable because he knows he is a key member of the team and has a lot more confidence.
