*Dustin Ackley: Second overall pick in the 2009 draft. Was Baseball America's 11th and then 12th-best prospect. Truth is, he didn't tear apart the minor leagues (.280), but did draw more walks than strikeouts, and his decent rookie performance (.273/.348/.417) suggested he'd develop into a decent hitter. Definitely the most difficult one here to explain. *Justin Smoak: No. 13 prospect in 2010. His 24 home runs in 702 minor league at-bats suggests his power potential was always overrated anyway. Maybe remaking himself as well ... he's drawing walks now but a .698 OPS from a first baseman isn't exactly middle-of-the-order material. *Jesus Montero: Minor league numbers were impressive for his age, but the fact that he hit worse his second year in Triple-A was probably a bad sign in retrospect. Remember, this guy was BA's No. 4, No. 3 and No. 6 prospect three years running based on his sure thing as a hitter. *Michael Saunders: A May 13 headline in the Seattle Times reads, "Michael Saunders has gone from flop to force at the plate." Since then he's hit .109 (5-for-46) and is down to .217 with a sub-.300 OBP. Was BA's No. 30 prospect heading into 2010. He now has over 1,300 major league PAs and owns a career .219/.283/.366 line. I thought he had a breakthrough last year but now all bets are off. *Carlos Triunfel: BA's No. 62 prospect after debuting in the States at age 17. Remained in the top 100 the next year. Power never developed, undoubtedly aided by his poor plate discipline (35 SO, 7 BB in Triple-A this year). *Adam Moore: No. 83 before 2010, his minor league numbers were good, not great, but he was a catcher. Hit .195 as a rookie. Then came a bunch of injuries. *Jeff Clement: Drafted third overall in the loaded 2005 draft, peaked at No. 33 on the BA prospect lists. Just a misfire. A costly one. *Jose Lopez: Peaked as Baseball America's No. 38 prospect and reached the majors at age 20 and even made the All-Star team his first full season. But his willingness to swing at pretty much anything (never walked 30 times in a season) ruined his career. *Jeremy Reed: Acquired from the White Sox in the Freddy Garcia trade, he had hit .373 with 70 walks and 36 strikeouts in 2003 between A and Double-A. But a .289 average in Triple-A in 2004, the year the Mariners acquired him, suggests a guy who was probably overrated as the No. 25 prospect. *Chris Snelling: Three-time top-100 prospect, as high as No. 39. Couldn't stay healthy. The one guy here who I'm convinced would have hit.
