Coming into this season, Rojas had a total of four home runs in 358 games, with exactly one in each major league season. His aggregate 4.2 WAR was also nothing special. This season, Rojas is now up to nine home runs, with a 2.8 WAR. Where exactly is the power coming from?
Rojas’ first three seasons with the Marlins would see him barrel exactly one ball, according to baseballsavant.mlb.com. He’s tripled that output this year, but still, that’s just three. His exit velocity, which is 83.6 MPH through his career, is only the slightest tick higher than in seasons past, at 84.
