BP Daily: Reality check, part I

At the beginning of the month, we discussed some of the issues surrounding spring training statistics and what they might mean for hitters. It's difficult to figure out which players are making legitimate improvements to their approach and production, but there are ways to try to identify those who are doing just that. On Tuesday, we'll take a look at some players who have been having impressive or poor springs but have one thing in common: The numbers they've put up are not worth getting excited about, one way or the other.

Mark Teahen is a player who has driven analysts and fans crazy the past few seasons. He alternates between having potential, displaying that potential and flushing that potential down the toilet by refusing to pull the ball consistently. This spring, Teahen has slugged an even 1.000, hitting three home runs along with a double and a triple in just 20 at-bats.
