Free speed: White Sox promote prospect Tim Anderson

If you're a fantasy owner in need of speed, the Chicago White Sox are here to help.

The team called up shortstop prospect Tim Anderson to the big leagues on Friday, and we can assume he wasn't promoted merely to sit and watch. Chicago also DFA'd veteran Jimmy Rollins, clearing a path for the 22-year-old Anderson.

Over 55 games at Triple-A Charlotte this season, Anderson has slashed .304/.325/.409 with 16 extra-base hits, 11 steals and 39 runs scored. He was almost unstoppable in the month of May, hitting .349/.387/.488. Anderson has 19 multi-hit games in his last 30, which seems absurd. Last year, the kid led the Double-A Southern League in hits (160), runs (79) and steals (49), plus he ranked third in batting average (.312) and triples (12). The speed is definitely real. Anderson has hit .300 or better in each of the past three seasons, too, so he isn't likely to be a liability in AVG for fantasy purposes.

We should note, however, that Anderson is something less than a flawless prospect. He's drawn only eight walks this season and 32 in his last 180 games; we're not talking about a player with exceptional on-base skills. He's a steals-only add, basically. But for many of you, that's enough.
