Danny Duffy will face Carlos Zambrano in just a few minutes. The skinny on Duffy: high three-quarter delivery, left-handed, throws hard, rookie. He was a 3rd round pick in 2007, right out of High School.

His Spring Training PITCHf/x data from 2009 and 2010 don't show a slider, but he is throwing one this year. This goes with his curveball and change-up, and of course his bread-and-butter four-seam fastball. I haven't ruled out (or in) two-seamers in the margins.
Although Duffy was a high-K low-BB pitcher in the minor leagues, he has struggled since his promotion. But his last outing was well in line with his minor league numbers.
