The Phillies are intent on getting Vince Velasquez deeper into his starts. Poor pitch economy is the oft-cited culprit of his short outings and also the focus of most offhand solutions. Here is the theory: by throwing fewer pitches to each batter, he will ultimately see more batters over the course of a game, and lengthier starts will follow. A well-conceived plan.
On a per batter basis, Velasquez does throw more pitches than the average starting pitcher. This is also true of Max Scherzer, Justin Verlander, Noah Syndergaard, and other pitchers ideal for Velasquez to emulate. Where the economical pitcher is averaging 3.7 pitches per batter, these pitching giants are throwing closer to 4.0. The reason: a big swing-and-miss fastball. Because these fastballs miss bats at a high rate, fewer balls are put into play. Deeper counts naturally follow.
Improving pitch economy, then, would require Velasquez to make his fastball more hittable. Or select a less effective pitch to throw. Either way, the idea is the same: cede contact and let the hitter get himself out. Hitters, it should be noted, have no such intention.
