Finding comparisons for Chris Tillman's sinker

Of the several high-ball pitchers that the Orioles employ, Chris Tillman is perhaps the most notable for his tendency to pitch up in the zone. I’m not at all sure why he does this when he a) pitches half the time in a park notorious for its homer-increasing effects and b) plays in front of a really good infield defense (at least on the left-hand side). But the fact remains his 39% flyball rate since 2012 is in the 80th percentile of qualified starters during that period.

So it was notable when, in July of 2015, Tillman began throwing a two-seam fastball (sinker) for what was just about the very first time in his career:
