Is Fernando Rodney tipping pitches?

We all know what Fernando Rodney did last year for the Tampa Bay Rays, posting one of the great relief seasons of all time, with a 0.60 ERA and converting 48 of 50 save opportunities.

That's why this report from R.J. Anderson of The Process Report has to make Rays fans a little nervous. ESPN's Mark Mulder pointed out the other night that Rodney might be tipping pitches, and R.J. has a couple screen grabs to look at.

Obviously, the Rays would notice this and it would seem correctable. But it does raise the question of what we can expect from Rodney in 2013 -- and that's aside from whether or not he's tipping his pitches.
