Iglesias turned his changeup into a pure swing and miss pitch last season, getting a huge bump to a 40.6 K%. He remains one of the best closers in the National League, registering a career-best 34 saves for the Reds. His changeup is above average for both vertical and horizontal movement.
Averaging 84 mph, Iglesias’ slider had a 16.9% swinging-strike rate in 2019, netting him nearly a 31% K rate. The pitch has average depth, but gets 10.6 inches of horizontal break, compared to the 4.2 inches the average major-league pitch gets.
Iglesias has a four-seamer that sits 95.4 mph, but can touch the high-90s. It is fairly straight, getting both average movement on both planes, compared to the average major-league four-seamer. That didn’t stop the pitch from being an effective offering for the Reds closer, with a resulting .239 BAA and a 32% K rate.
Iglesias fortified another strong season in spite of his four-seamer surrendering a negative pVal (-1.2) for the first time in his career. Opponents staked it to nine home runs—he allowed five total long balls in 2017—and laced a 35.1% line-drive rate. His recipe for success might call for even more sliders and changeups in favor of his heater.
Turning to more changeups, Iglesias unleashed his slider at a career-low 26.4% clip. Yet he sustained 2017’s elite success with the wipeout pitch by posting a .174 opposing wOBA and 48.6% strikeout rate.
After sporting a subpar change in past years, Iglesias leaned more on a revamped version of it in 2018. With the usage rate spiked to 22.4%, the pitch induced a .189 wOBA and 59.6% ground-ball rate. It fared even better than his strong slider in terms of limiting contact (57.0%) and gathering whiffs (26.5%). The changeup’s success should help Iglesias maintain his status as an elite late-inning reliever.
