While it may be difficult to ever top his 2009 campaign, Zack Greinke is crafting one of his best seasons in 2014.  He’s posting a sparkling 2.65 ERA through 139.1 IP (matched with a 2.82 FIP and 2.60 xFIP), excellent K/9 and BB/9 numbers (9.88 and 1.87, respectively), and a career best 50.0 percent groundball rate. Surprisingly, he’s performing at a high level despite a .322 BABIP, the second highest of his career.

Greinke’s pitch selection may be the biggest catalyst for his recent dominance.  He is emphasizing his change-up this year, raising its frequency from 12.2 percent to 16.2 percent.  The result?  A jump from 3.6 runs above average for his slow pitch in 2013 to 8.4 runs above average in 2014, which could easily end north of 10 by season’s end.

Take a look at his improved change-up as he struck out Jordan Schafer during last week’s game against the Braves:


As you can see above, hitters are having much more trouble making contact against Greinke this season.  With his increased change-up usage, his whiff rates have inflated.  Greinke’s O-swing rate (the frequency at which hitters swing at pitches outside the strike zone) stands at an incredible 37.4 percent, a  career high and fourth best in the MLB.  For reference, his excellent 2009 season featured an O-swing rate of only 26.9 percent.  As one would imagine, his overall swinging strike rate followed suite as well, sitting at a career best 11.7 percent in 2014.

Zack Greinke looks to have made big strides this year, with large thanks to his much improved change-up.  He’s a new pitcher in 2014, and well on the path to reclaim his seat among the elite starters in the majors.
