After spending four seasons in the Venezuelan Summer League, Medina finally made his U.S. debut in 2010. He pitched well in the lower minors, won an emergency start in Triple-A and was rewarded with a spot on Seattle's 40-man roster at the end of the season. Nicknamed "El Caballo," Medina is a workhorse at 6-foot-3 and 210 pounds. He showed one of the best breaking balls in the short-season Northwest League, a sharp curveball that generates a lot of swings and misses and projects as a plus pitch. He sets up his curve with a 90-91 mph fastball that gets up to 94. He mixes in a splitter as a chase pitch, as well as a changeup to keep hitters off-balance. Mechanically, Medina is working to better incorporate his strong lower half into his delivery. His command and control also need improvement. With his relatively advanced age, sharp breaking ball and competitive nature, the Mariners could challenge Medina with a promotion to high Class A at some point in 2011.
Minor League Top Prospects
While lefthanders Edlando Seco and Anthony Fernandez put up better numbers, Everett's best starting pitching prospect was Medina. Big and physical, he had one of the best breaking balls in the NWL and sets up his curve with a 90-91 mph fastball that gets up to 94. Medina also uses a splitter as a chase pitch and keeps hitters honest with his changeup. Mechanically, he needs to do a better job of incorporate his lower half into his delivery. "I call him El Caballo," AquaSox pitching coach Rich Dorman said. "He's just a horse and he's one of the most competitive kids that I had last year."
