"Mlb held up the call"...

What are you talking about?

Its by rule a non reviewable play.
It is a Judgement call by the umpires.

The reason for the rule was to stop the trend of blocking the bag on stolen base attempts.
Did you even see the play?


The umpires for that game conferred. There was no replay review by mlb.
MLB wasnt involved.


Its telling what brewers manager pat murphy said about the call. "It sucks to lose a game in that manner"

Managers on the winning side of a umpires call dont say such things when the umpires call is appropriate. Applied correctly.

Key phrase in the rule, its in not obstruction when a player blocks the bag in the act of applying the tag or receiving the ball.

If this play is correct as jordan baker applies the rule. Then 90% of pickoff attempts at 1b are "obstruction", as every 1st baseman sets up to take the throw with his foot blocking part of the bag.
