Accardo's striking out a batter an inning and has a 3:1 K:BB ratio so his success doesn't appear to be a fluke.
However, Janssen has just 10 Ks in 24.1 innings - just 3.7 Ks/9, and that's out of the bullpen. Janssen is a groundball pitcher, but certain not an extreme one - he's in the 1.5 GB/FB range.
Obviously they won't be able to keep this up over the course of the season, but where do each of them end up?

Friday: Jesse Litsch vs Scott Baker
Saturday: Tomo Ohka vs Ramon Ortiz
