The Arizona Diamondbacks traded veteran slugger Mark Trumbo and relief pitcher Vidal Nuno to the Seattle Mariners this afternoon. In exchange, Arizona receives pitcher Dominic Leone, catcher Welington Castillo, and a pair of prospects: outfielder Gabriel Guerrero and infielder Jack Reinheimer. Here's a look at the two prospects joining the Dbacks organization.
Gabriel Guerrero, OF: Gabriel Guerrero was signed by the Mariners as a free agent from the Dominican Republic in 2011. The nephew of retired major league superstar Vladimir Guerrero, Gabriel had a solid 2014 season in the California League, hitting .307/.347/.467 with 18 homers and a Futures Game appearance. However, the league/park context was friendly to his skills and it remained to be seen how he would handle advanced pitching. So far, he is not doing very well, hitting just .215/.262.305 with 48 strikeouts and 12 walks in 177 at-bats for Double-A Jackson.
Guerrero is a 6-3, 190 pound right-handed hitter and thrower, born December 11, 1993. He resembles his uncle with his raw power and strong throwing arm, but his strike zone judgment is quite shaky and his hitting approach very aggressive. So far Double-A pitchers have been able to contain him. He is still young enough to improve, but his production outside the Cal League has yet to fully match the physical tools.
Jack Reinheimer, INF: Reinheimer was drafted by the Mariners in the fifth round in 2013 from East Carolina University. He spent most of 2014 with Clinton in the Low-A Midwest League, hitting .264/.333/.335 in 110 games. Moved up to Double-A Jackson this year, he's hit .277/.323/.351 in 202 at-bats with 12 steals in 13 attempts.
Reinheimer is a right-handed hitter, born July 19, 1992. Although his natural physical tools are just average, he is a very polished defensive shortstop due to instincts, positioning, and fundamental reliability. He's also very good at second base. Offensively, he is a line drive hitter and makes ready contact, but he lacks distance power and is not especially patient. He runs well and is an adept stealer, but without more power or a higher OBP he won't hit enough to play regularly. He could be useful on the bench due to his defensive versatility.
