Haze, I hate to take you to task, but it's quite possible that Vazquez is NOT fine.
When a pitcher is tipping his pitches, there's a problem in his mechanics. It could be something as simple as a maneuver the pitcher makes with his glove on certain pitches. If that's it, it's easy enough to repair. But if there's an issue in his delivery that is giving hitters a legit clue as to what they're about to see, it's a major problem...and very likely the same one that plagued Vazquez throughout the second half of last season as well as in spring training.
Again, I don't know what is causing Vazquez to tip his pitches, but rest assured that in the majority of such cases, the solution is far from a cinch. And if that's the situation for Vazquez, he's going to be anything but fine, at least for the near future.
