I would say this is pretty conclusive evidence of why Yankees pitcher Mariano Rivera is able to throw only one pitch that has unpredictable, yet precise movement.
He has mastered the Angels so far in the ALCS but has Major League Baseball gotten a look at how he "warms up" for his appearance on the mound? You be the judge...
With a tie game in the bottom of the 10th, the Yankees bring in Rivera.
After warming up, he has his back to home plate so the home plate ump can't see.
He looks down at the ball, then up to see if the 2nd base ump is watching.
He then looks back at the ball and appears to spit on it.
And when he tests clean for steroids they say he is not a cheater.
Total and complete nonsense. First of all, Rivera wouldn't look down at a baseball and drop spit directly from his mouth onto it. Secondly, he'd have to have been doing this for 15 years, and nobody noticed until now. Thirdly, baseballs get changed out so often, he'd have to do this 5-10 times per game.
Absolute nonsense, and even though the Angels won, total sour grapes by their fanbase.
By the way, here's a slowed-down video of the incident, which clearly shows the spit travels past Rivera's hand and the ball and travels to the ground. Funny that the Angels blogs decide to show misleading screenshots rather than the entire video:
