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.
By the numbers: Fastballs account for 61.2% of Barco's 232 tracked pitches in 2026, compared with 26.8% breaking balls and 12.1% offspeed pitches. The sweeper has generated a 30% whiff rate and a .150 wOBA across six plate appearances.
What to watch: Watch whether Barco increases his sweeper usage and scales back pitches producing weaker results.
