Rob Kaminsky drops out of our top five, falling nine spots from our 2016 prospect rankings. The 22-year-old left-hander joined the Cleveland Indians at the trade deadline in 2015, coming over from the St. Louis Cardinals for Brandon Moss.
Standing just 5-foot-11, he was originally the 28th overall pick in the 2013 draft, taken by the Cardinals out of high school in Montvale, New Jersey. The former top 100 prospect in baseball spent the 2016 season at Double-A Akron where he helped lead them to the Eastern League Championship.
