On Wednesday night, Atlanta hurler Jair Jurrjens continued his fantastic rebound season with another lights-out effort against the Rockies. Jurrjens allowed one earned run on five hits and two walks over six innings.

He reduced his ERA to a ridiculous 1.87 mark (1.06 WHIP) and earned his 12th win of the season. Jurrjens has achieved these heights despite posting a low strikeout rate of 5.3 batters per nine innings. It’s helped markedly that Jurrjens has averages 2.03 walks per nine innings.

When you look into the splits, nothing stands out in the raw stats. His groundball-to-flyball ratio is sub-1.00, and I’ve already mentioned the low strikeout rate. Still, Jurrjens has made pitches when they’ve counted, and he’s been ultra-efficient. He completes innings at an average of 14.4 pitches per frame to tie for fifth in Major League Baseball. Interestingly, Jurrjens has earned decisions in 15 of 16 starts.
