Currently a free agent, Tropeano’s changeup proved to be capable of missing bats as it recorded a well above-average 18.5% swinging K rate (48% whiffs). It was just an abbreviated 55 pitch sample, but his changeup has shown plus bat missing ability before. Looking back at 2018, it recorded a similarly impressive 53% whiff rate.
Tropeano featured his slider notably more against opposing RHB (47/66). In a brief sample this year it proved plenty capable of missing bats as it returned a 16.7% swinging K rate and 42.3% whiff rate. Tropeano’s slider held a similarly impressive 41.1% whiff rate back in 2018 too.
Tropeano’s slider and change are both respectable bat-missing pitches. His fastball, however, seems to be a liability. Averaging just over 90 mph, it has allowed a wOBA of over .380 in each of the past two seasons.
Tropeano’s splitter features excellent drop and returned a very respectable 16% swinging K rate and 36.4% whiff rate. Though it remains a lesser part of his arsenal as he has thrown it at an under 15% clip in each of the past two seasons.
Tropeano threw his true four-seamer 27.3% of the time, which was just a touch more than his slider at 24.3%. The fastball was not a highlight for the Stony Brook product. It was hit really, really hard, averaging a gruesome 93.6 mph average exit velocity while allowing a .380 wOBA (.433 xwOBA).
Tropeano’s primary breaking pitch, the slider was an effective whiff pitch for him in 2018. It had good marks across the board with a 37% chase rate, 36.7% zone rate, and a 17.8% swinging-K rate (41.6% whiff rate). It did allow four home runs and a .347 wOBA, suggesting that it had a tendency to get hit hard when located poorly.
Tropeano doesn’t throw too hard. His sinker averaged just a shade under 90 mph last year. It may have been the recipient of some good batted ball luck in 2018, as its wOBA of .305 was much lower than its xWOBA of .369. As you’d expect, it didn’t miss many bats, with a low 11.1% whiff rate.
Not as effective as his splitter, Tropeano’s changeup, which he threw just a hair more often than the splitter at 14.3%, had a 30.8% chase rate, 31.9% zone rate and 19.1 % swinging-K rate. He threw it almost exclusively to lefties (137/169). The batted-ball results were not too great, as it allowed a .415 wOBA (.345 xwOBA) and a .313 batting average.
He didn’t throw the splitter much (13.5%), but it was impressive. It came close, but did not quite become a Money Pitch for Tropeano last year. It featured an impressive 44.7% chase rate, a 35.2% zone rate, and a 21.6% swinging-K rate (42% whiff rate). It also held hitters to a .195 batting average and .240 wOBA.
