Floro threw his change just 28 times, and mostly to left-handed batters. It managed a pretty rough 6.7% whiff rate and a similarly unappealing 25.7% zone rate. It’s easy to see why it’s Floro’s third offering.
Floro’s fastball averaged just about 94 mph, topping out at just under 97 mph. He featured the four-seamer mostly up in the zone and the results were reasonable, as it held batters to a .336 xwOBA and managed a 24.4% whiff rate.
The slider was Floro’s best whiff pitch. It showed a 15.9% swinging-strike rate (33.7% whiffs), 37% zone rate, and a 33% chase rate. The batted-ball results were excellent, as it held hitters to a paltry .213 wOBA.
Floro featured a two-seam fastball with excellent arm-side run and sink, and the result was a 62.2% ground-ball rate over 64 innings in 2018. Floro’s extreme ground-ball tendencies helped limit opposing hitters to a .070 ISO, which allowed him to survive a .340 BABIP. While his two-seamer gets an above-average amount of swinging strikes for a two-seamer, he’s far from dominant with a 7.2% swinging-strike rate.
Floro’s slider is a fairly average slider on the surface but has produced excellent results as a complement to his two-seamer. Last year, Floro racked up a 53.7% ground-ball rate with his slider to go along with a 15.8% swinging-strike rate. The result was an ISO of .086 that, when coupled with his two-seamer, did an excellent job suppressing home runs.
Floro occasionally mixed in a four-seamer late in the count and had an impressive 14.6% swinging-strike rate while throwing it in the zone 52.9% of the time. His four-seamer had a huge 42.9% strikeout rate in limited usage, giving it potential to be used more often.
Floro threw 84 changeups in 2018, and while it had some promising swing rates, it was ultimately undone by six extra-base hits in the limited sample. While it provides a needed change in velocity, he can probably do without it from the bullpen if his other pitches continue to excel.
