Reportedly Kimbrel just learned before Game 5 that he has been tipping his pitches in recent weeks, allowing batters to tee off on him (though all the walks still seem to me to be a big part of the problem, too). If this info is right and he has now corrected the problem then that bodes very well for the World Series:

After the Game 4 near-disaster with Kimbrel, Pedro Martinez (on the TBS post-game show) kept saying: "Kimbrel is hitting the target late".
I assume that's the specific spot in the center of the catcher's glove where he's aiming the ball?
Pedro Martinez has been sort of a pitching coach lately for the Red Sox... at least he was a few years ago.
Anyway... hope Kimbrel gets his stuff right before the World Series. He's been causing massive heart attacks throughout Red Sox Nation. :-/
