In the run-up to unveiling its 2013 Top 100 Prospects list Tuesday evening, MLB.com has been revealing its top 10 rankings for each position. The top outfielders were the last ones to be announced, and the top three of them are former Midwest League players.

Topping the list is St. Louis Cardinals prospect Oscar Taveras, who played for the 2011 Quad Cities River Bandits (.386, 8 HR, 62 RBI in 78 games). Calling him “perhaps the best pure hitter in the minors,” MLB.com reporter Jonathan Mayo wrote that “Taveras has done nothing but hit for plenty of average, and the power continues to come, along with improved plate discipline. He has everything to be an All-Star-caliber outfielder who hits in the middle of a big league lineup for years.”

Tampa Bay Rays prospect Wil Myers is ranked second among outfielder prospects. He was drafted as a catcher by the Kansas City Royals and played that position with the 2010 Burlington Bees (.289, 10 HR, 45 RBI, 10 SB in 68 games). Mayo wrote that Myers’ offense is big-league ready and “replete with plus bat speed and outstanding on-base skills.”

Cincinnati Reds prospect Billy Hamilton, who moved from shortstop to center field in the Arizona Fall League, is ranked third among outfielder prospects. He batted .278 and stole 103 bases in 135 games with the 2011 Dayton Dragons.

Mayo wrote the following about Hamilton:

The 2009 second-round pick was settling in nicely to his new environment, with his plus-plus speed allowing him to outrun any mistakes as he learned how to read the ball off the bat and get better jumps. That outstanding speed makes him perhaps the most exciting player at any level, and the one who broke the professional single-season stolen-base record last season with 155. He’ll become a better and better leadoff hitter as he continues to hone his on-base skills.

The Top 100 Prospects list will be unveiled beginning at 8 p.m. CT Tuesday on MLB.com and MLB Network.

Cedeno signs with St. Louis

Veteran infielder Ronny Cedeno agreed to a one-year, $1.15 million deal with the St. Louis Cardinals. He hit .211 with 3 HR, 33 RBI and 14 SB in 115 games with the 2001-02 Lansing Lugnuts.
