Miami Marlins reportedly set to promote Jordan Yamamoto

The Miami Marlins are reportedly set to promote prospect Jordan Yamamoto to the majors.

For Miami Marlins fans, one of the biggest questions involves when they will see some of their top pitching prospects. Zac Gallen has been dominant at AAA, but there is not yet room for his presence in the rotation. Nonetheless, Marlins fans have been waiting for that wave of prospects to begin to make an impact at the major league level.

While Gallen is not forthcoming, at least just yet, another pitching prospect is set to get the call. According to reports, Jordan Yamamoto will be promoted to the Marlins on Wednesday.

Heading into the season, Yamamoto was actually ranked above Gallen on the Marlins top 30 prospect list on MLB.com. While Gallen has captured the attention of prospect watchers and Marlins fans alike, Yamamoto has had a solid season as well.

In his first full season at AA, Yamamoto showed the potential that made him an intriguing part of the Christian Yelich trade. He posted a 3.58 ERA and a 1.194 WHiP, striking out 64 batters with 25 walks in 65.1 innings. This follows an excellent 17 inning stint in AA last year, where he allowed six runs, four earned, on 12 hits and four walks, striking out 23 batters.

Yamamoto is not an impressive physical specimen, standing at 6′ tall and weighing 185 pounds. His fastball sits only in the upper 80s to lower 90s, hardly the type of velocity that would generate such solid results. Yet, he has an above average spin rate on the heater, a plus curve, and a solid change that allows him to pitch beyond what his stuff would usually entail.

For now, the Marlins are expected to use Yamamoto out of the bullpen, perhaps in a multi-inning role. That may ultimately be his place in the majors, as he is considered to be anything from a middle of the rotation arm to a possible fireman, depending on the development of his secondary pitches. With his command and ability to keep the ball in the park, he has developed into an intriguing arm for the Marlins.

Jordan Yamamoto is reportedly about to make his major league debut. His future may be decided if he performs well during his stint in the bullpen.
