21-year old righty reliever Mark Montgomery came into this season as the Yankees’ #23 prospect according to Baseball America. Montgomery has pitched in 44 games (0 starts) in A+AA-ball so far this year and he is 7-2 with 15 saves, a 1.61 ERA and a 0.93 WHIP. He has only given up 35 hits and 22 walked in 61 1/3 innings while whiffing 95 batters so far this year and those are amazingly good numbers. Montgomery has now pitched in 70 games (0 starts) in his first two years in the minors for the Yankees and he is 7-2 with 30 saves, a 1.71 ERA and a 1.00 WHIP. He is looking like a really good prospect for the Yankees.
