Tabata breaks up perfect game | MLB.com
Just a couple observations:
1) Even though it sure looks to me (with the benefit of replay) like the batter purposefully moved his elbow into the pitch, I cannot fault the HP Umpire for ruling HBP. This would be very difficult to see.
2) BrooksBaseball PITCHf/x showed the pitch to be about 7" inside the plate. A pitch does not belong in the Batters Box and if it goes there you will seldom get the benefit of the doubt.
3) Per MLB review criteria
"Notwithstanding the foregoing, whether the ball was in the strike zone when it touched the batter, and whether the batter made any attempt to avoid being touched by the ball, shall not be reviewable." So no, it is NOT reviewable.
