I got Renteria in the 19th round of my draft and the guy is absolutely tearing the cover off the ball I think he is around 10 RBI already and hitting well over .300. I guess after last year people thought he was overrated. Another sleeper I picked up was Preston Wilson, took him in the 21st round, .300, 4 HR, 7 RBI. And last but not least, one of my favorite non Red Sox Orlando Cabrera. I actually got this guy in like the 24th round, he has 2 HR, 2 SB, is hitting like .350 and scoring alot of runs.
Not sure if these guys will keep it up...but there playing good now and I got them cheap.
