At baseball-reference.com they've introduced spring stats this year and they have a rudimentary little tool that shows the level of competition the player has been facing. Not perfect, but it helps balance out the bias a little.
As for stats themselves, they don't matter much for guys who are assured a spot on the Opening Day roster, as this is a time to get ready for the season, work on some stuff, etc. I think Peavy said yesterday in his start against San Diego when he allowed 3 runs in 3 innings, he was working on his fastball so he threw that pitch almost exclusively. But for guys fighting for the last roster spot, I think there is some minor importance to them, but like a lot of baseball, a lot depends on the eye test, as well.
