Protecting a four-run lead in the ninth, Joe Nathan walked the two batters he faced Wednesday night at Comerica Park. At one point, he'd thrown eight balls and five strikes.

Needless to say, the sellout crowd at Comerica Park wasn't happy, as boos rained down.

Apparently, neither was Nathan, who got a flyout and a double play to end the game.

This was recorded off the ROOT Sports feed by Malinda Mosholder.

You be the judge.

[UPDATED: Nathan apologized for his actions Thursday morning.]
