Mason Martin

From an offensive standpoint, Martin appears to be the steal of the 2017 draft, and it's not particularly close. He fell to the 17th round (508 overall), which oversells things a bit, as his $350,000 bonus was the sixth largest from the Pirates' draft class. Nonetheless, he was the Gulf Coast League's best hitter (198 wRC+) and won't turn 19 until June, so it's not like he was a college hitter taking advantage of pitchers who were two and three years younger than him. His left-handed bat should profile anywhere, which is good, as he is seen as a 1B-only prospect, and his glove is even below average at first base right now. Martin has huge raw power, which will be his carrying tool, but he should also excel at getting on base -- he walked at a 19.3 percent clip in the GCL. His pull-heavy approach (50 percent) puts a bit of a cap on his batting average as he moves up the ladder, but he has plenty of time to refine that aspect of his game.
