ANALYSIS: New York Yankees starting pitcher Will Warren has made quite a splash lately, striking everyone out over his last handful of starts.

A quick look at his movement profile is warranted here. Baseball Savant says all four of his secondary pitches (sinker, sweeper, changeup, curveball) have above-average vertical and horizontal movement.

He's leading with his four-seamer, but at only 35% usage, he's not overly dependent on it. It's not a nasty fastball, just very average in velocity and movement. His sinker is not quite Logan Webb's quality, but it drops nearly four inches more than the average sinker and features 17.6 inches of arm-side run.

The sinker pairs incredibly well with Warren's best pitch, his sweeper. The sweeper has an average horizontal break of 20 inches, and it's no coincidence that he's upped his strikeout numbers by throwing it more often.

He's throwing out of a very low arm slot, which helps him achieve such elite horizontal movement. He still needs to fine-tune his control a bit with a walk rate approaching 9.0%, but he's shown some significant improvement lately with just three walks over his last three starts combined.

Warren's only real red flag is his hard contact rate. But I think we can live with it being that high if he continues to miss bats as often as he has lately.

Warren appears to be breaking out in a big way for the Yankees in terms of his strikeout potential. It's still a small sample size of innings, but he has the talent and profile of a pitcher who could be very good and is worth investing in right now.
