Duran discovered the signature pitch by accident during a bullpen session in 2018. This season, he’s thrown the pitch nearly 40% of the time and is holding opponents to a .221 average.

Those four pitches were all splitters as Duran finished out a Phillies comeback victory over the Tigers to take the series opener -- and regain first place in the National League East. In one of the most electrifying games of the year, Duran stole the show in his debut.

New Phillies closer Jhoan Duran is thrilled to be in the City of Brotherly Love after his first save with his new team.
