Heading into this season Baseball America ranked Kansas City left-hander John Lamb as the 18th-best prospect in MLB, but the Royals just announced that the 20-year-old former fifth-round pick will miss the remainder of season following Tommy John elbow surgery.
Lamb was one of nine Royals prospects to crack Baseball America‘s top 100 list after throwing 148 innings with a 2.38 ERA and 159/45 K/BB ratio between two levels of Single-A last season and was off to a strong start this year at Double-A, posting a 3.09 ERA in eight starts despite being extremely young for the level of competition.
Now he may not pitch again until mid-2012, which shows how even a historic stockpile of prospects can detiorate in a hurry. Of course, losing Lamb barely makes a dent in the Royals’ abundance of young talent and he’s so young that taking two entire seasons off would still leave him as one of the youngest pitchers at Double-A when he returns. Still, a tough blow for one of the game’s elite pitching prospects.
