With the minor league season roughly half over and some leagues holding All-Star games, this is a good time to look back at the first half and see which Pirate prospects managed to alter their status, for good or ill. In Part 1 I'll cover the position players; pitchers tomorrow.
Josh Harrison, UT (MLB): Harrison will always face questions due to his small size, and his lack of power and weak defensive skills will keep him from claiming a regular job. But he actually improved his hitting from AA to AAA, adding over 70 points of OPS, and hasn't been at all overmatched since the Pirates called him up. Just three strikeouts in 49 at-bats in his first taste of major league pitching is a difficult feat, although the fact that he's walked only once indicates another potential limitation if he doesn't start taking more pitches. He's at least established that he has a future in the majors. He may even turn the Cubs trade into a wash.
