In this day and age advanced baseball statistics provide an absurd amount of information.
You seemingly can find evidence to support virtually any claim, positive or negative, about a player's production.
The same is true of Ryan Vogelsong.
While you could pick apart his various splits and point to all of his glowing achievements this season, they also reveal potential pitfalls for 2012.
Looking through Vogelsong's sabermetrics reveals two areas in which he was the beneficiary of a little luck in this season.
The first telling stat is Batting Average on Balls In Play, or BABIP for short.
For a proper frame of reference consider the following information from fangraphs.com:
"The average BABIP for pitchers is around .290 to .300, and pitchers have much less control over their BABIP than batters. To what degree pitchers can influence their BABIPs is still up for debate, but even dominant pitchers have average career BABIPs that deviate just slightly from the .290 to .300 range."
Vogelsong's .285 BABIP this season is not ridiculous, but it is safe to assume that this number will rise closer to the norm.
The second notable area can be seen in opposing batters' numbers with two outs and runner(s) in scoring position (RISP).
Opponents hit only .153 with a .216 BABIP with two outs and RISP. The batting average against in this situation is 91 points lower than the overall average of .244.
This represents a remarkable combination of clutch pitching with some added luck from the BABIP.
Whether you cite luck, or clutch pitching, Vogelsong will be hard-pressed to maintain that level of effectiveness next season.
