I was watching the Yankees/Rays game on ESPN and... ugh... rooting for the Yankees (I just puked in my mouth a little) and I saw some history.
In the top of the 9th with the Yankees already up 6-3 (so it wasn't really clutch), A-Rod launches a fly ball over the left field pole. Called a homer... but WAIT... they will use INSTANT REPLAY!!! For the first time ever they reviewed a home run call with technology and not the eye ball method that has been in use since the 1700's when they threw an onion and hit it with an ivory cane.
The result? Well... I couldn't really tell. But the umps seemed to find enough evidence to keep it fair and the Yankees ended up winning 8-4 and got the Sox another game closer to the Rays.
So, thanks A-Rod! You douche.
