After the 2010 season, Phillies second baseman Cesar Hernandez looked like a potential breakout prospect. 

Hernandez hit .325/.390/.392 for short-season Williamsport that year as a 20-year-old, but he struggled last year in an aggressive assignment to skip a level to high Class A Clearwater.

Now in Double-A Reading, Hernandez is showing the offensive signs of life he flashed earlier in his career. Hernandez, 22, went a combined 4-for-6 with a triple yesterday in a doubleheader, bringing him to .325/.358/.459 through 58 games. He's a switch-hitter who has a better swing from the left side, where he has more ability to put some sock into the ball, but he's always going to be more of a line-drive guy than a power hitter. There probably isn't huge upside with Hernandez, but he gets the most out of his tools, can play in the middle of the diamond and has good bat control, so there should be some type of role for him in the big leagues within the next few years, either as an everyday guy or someone coming off the bench.
