A Closer Look at Jordan Yamamoto
Jordan Yamamoto was ranked 23rd on the site’s 2019 Marlins prospect list, given a 40-grade future value as a potential backend starter. The right-hander, who came over in the Christian Yelich deal, was credited for his pitchability and depth of arsenal that would allow him to carve out a role in the backend of a rotation or as a multi-inning reliever. A 12th-round pick back in 2014, Yamamoto has put up a 26% strikeout rate, 7% walk rate, 3.75 ERA, and 1.24 WHIP in 463 innings. He put up a 3.58 ERA, 1.19 WHIP, and 14% K-BB in 12 starts at Double-A which earned him the call.
His prospect profile highlighted his four-pitch arsenal (FB, CB, SL, and CH), but may have sold him short as he’s also shown a cutter in his two MLB starts (though the CH has been relegated to a show-me pitch). The scouting report was AFL-focused as he threw 26 solid innings back in October/November so it was the freshest look at Yamamoto. His fastball was high-80s, with dips down to 86 mph, though there was a high end of 94 (not sure if that was done at AFL or during the 2018 season). This capped some of his upside per Eric and Kiley:
