What happened: Barco uses his slider 17.7% of the time, followed by the sweeper at 9.1%, changeup at 6.9% and splitter at 5.2%. His four-seamer averages 94.3 mph, while the sinker averages 93.7 mph.

Why it matters: The varied movement profiles give Barco options on both sides of the plate. His 15.2% whiff rate and 19% chase rate show that the deeper arsenal has yet to produce consistent swing-and-miss results.

What to watch: Watch whether Barco increases his sweeper usage and scales back pitches producing weaker results.
