"SABR types" will debate endlessly whether clutch hitting is real or just our imagination. But sometimes you really do have to ignore the raw numbers.
There's no doubt in my mind after watching David Freese in the past two series vs. the Brewers and the Rangers that he hits better when the pressure is on than than when there's not, and also he hits better in the clutch than almost anyone else would in the same circumstances.
I'm sure someone can trot out stats and graphs that clearly demonstrate that Mr. Freese has been really lucky the past month, and his past history shows he's not substantially better in the clutch than at other times, and he falls close to the league average in clutch situations. But eyes don't lie. When the game is on the line, I believe Freese would get a hit or do something to help his team win the game more often than superstars like A-Rod or Bonds.
