He made his big league debut last year, looking absolutely superb in seven starts and 35 IP. Delgado actually improved his homer rate from Triple-A, and remains in competition for the fifth starter in Atlanta this season. He had a decent record in Double-A, but his strand rate at Triple-A was higher. Delgado has superb mound presence and features a low-90s fastball, a tremendous changeup, and a fine curveball. He could top out as a No. 2 starter in time.

Well, he continued to play the majority of his games at short, but still saw plenty of action at second last year, just in case. A lot of experts are not listing him this high, and if he can’t stick at short, you definitely have to bump him up a few slots. Still, Franklin’s ability to play multiple positions will guarantee him of playing time once he reaches the majors. He struggled with the bat this spring and was recently farmed out, but this kid will hit big league pitching in time. Franklin missed time with injuries last year, but he flashed decent pop at High-A before heading to Double-A, where his batting eye regressed (although his bottom line numbers were excellent). One of the top prospects in a Mariner system that’s now brimming with impact talent, Franklin just turned 21, and while the power he flashed in 2010 evaporated, we’re willing to cut him some slack because of his health. A solid AFL showing suggests he’s back on track, and if Franklin can regain his power stroke at Double-A this year, he’ll be knocking on the door of Em City real soon.

Several experts aren’t as bullish on May as we are, but after he broke through with a double-digit win effort at Class-A, he’s cracked our list this season. His strikeout rates are very exciting, and he also made big strides in improving his control last year. May’s been extremely stingy with the gopher ball and this 21-year-old righty has a perfect pitcher’s build at 6’5”, 215. He brings three pitches to the table, the best of which is his Uncle Charlie, which is an above-average offering.
