Stop me if you’ve heard this before: with an improved pitch, a pitcher has significantly upped his performance. In my last two pieces, I wrote about Bud Norris’s and Mike Leake’s cutters, both of which have pushed them to another level. Today, I turn back to the American League, with a discussion of the Kansas City Royals’ surprising top starting pitcher: Jason Vargas.

Despite this, Vargas has a 1.01 ERA in 44 2⁄3 innings pitched this season, with FIP (2.16) and xFIP (3.70) numbers that would be career-bests over a full season. And, it wouldn’t even be close.
