Outfielder Estuar Suero
While FanGraphs agrees that Wolf is a noteworthy prospect and top 20 in the system, they don’t agree that he’s the best prospect the Pirates added. That would be young outfielder Estuar Suero. Suero came via the Hill/Choi swap, alongside Wolf. Suero is only 17 and is hitting .216/.206/.345 through 160 plate appearances for the Padre Arizona Complex League affiliate. He’s struck out 30.6% of the time with a solid 10% walk rate.
Suero is all about projectability and future power. He’s a tall, 6’5” teenager, and he’s only 180 pounds. That gives him some room to add some muscle, and fully grow into his body. FanGraphs loves his potential plus power/speed combo, giving him 60-future grades for both his raw power and speed. He’s also a switch hitter who has a good feel for center field. They state that he has “enormous upside”, though could be a slow-burner because he is a high-variance prospect.
