From now until the end of the season, we'll be giving you an updated report on prospects who appeared on Keith Law's preseason top 100 or midseason top 50 prospect rankings. Today we're taking a second look at a trio of Seattle Mariners prospects, Taijuan Walker, Nick Franklin and Danny Hultzen.
Walker was a projectable, athletic righty with a high ceiling when he went 43rd overall in the 2010 draft out of Southern California high school. He had a breakout first full season in low Class A, vaulting himself into top prospect territory, and he has only bolstered that with a solid performance in an aggressive assignment to Double-A. His stats have been solid for the league (4.22 ERA with 105 K's in 117 1/3 IP) but extraordinary given that he just turned 20 a few weeks ago at a level with many players in their mid-to-late 20s.
