Highly-ranked OF prospect Rymer Liriano reportedly suffered a tear on the ulner collateral ligament (UCL) in his right elbow and will undergo Tommy John surgery, forcing him to miss the 2013 season. Corey Brock of MLB.com has the details here.

The injury occured in December, when Liriano was working out in the Dominican Republic during a long toss session. Brock reports that the surgery will take place on  Wednesday.

Liriano, 21, is ranked #3 in the Padres organization by MLB.com and # 5 by Baseball America. He was signed out of the Dominican Republic in 2007 and in 2012 he excelled in his hiA assignment to earn a promotion to AA San Antonio. In 53 games at AA, Liriano posted a line of .251/.335/.337 but his numbers were much better over the last 26 games there (.322/.408/.444).

SAYS MLB.com – There is little Liriano can’t do on the field. He has tremendous bat speed, which should help him develop more power, and improved plate discipline has been a key to him becoming a better all-around hitter. It’s not just at the plate where Liriano needs to tone things down at times. He’s very aggressive on the basepaths and in the outfield, sometimes to a fault, but he should develop into a prototypical right fielder with a very strong arm, the ability to drive in runs and some baserunning skills to boot.

SAYS BASEBALL AMERICA – Built like a running back, Liriano features similar explosiveness in his game. He showcases all five tools at various points, highlighted by plus power, arm strength and range in RF…..Liriano has 20-20 potential if he puts everything together.

Tough break for Liriano and the Padres. Definitely not what they needed when competing with an NL west that is home to the defending World Series champion Giants, the star-studded Dodgers, a Rockies club that has Tulo and Cargo back in the fold and the 2011 champs in Arizona.
