One of the biggest revelations to come out of the Selena Roberts book on A-Rod was that the third baseman had tipped opponents has to what pitch was coming in games that were out of reach for one side. Those around the game commented and Major League Baseball is investigating, reportedly.

However, in combining Tom Tango's Leverage Index stat with data collected by Sean Forman of Baseball-Reference.com, Dan Rosenheck of the Times reports that the numbers don't support these events. In summary:

If a tipping conspiracy were in place, one would expect that Rodriguez and rival middle infielders in games he played to have hit better in low-leverage situations than in high-leverage ones. Using a fairly loose definition of high leverage as a L.I. above 1.5 and low leverage as below 0.7, the data provide a resounding answer: either no tipping was going on or it was pathetically ineffective.

There is more to look at, so check out the article. And, of course, this doesn't mean that Rodriguez didn't engage in pitch tipping. Even if you know what's coming, that's no guarantee you'll actually hit it, let alone reach base. But, the numbers are interesting to ponder.
