Alejandro Bedoya has his say on penalty shout vs. NYCFC in Knockout Round

In the first half of the Philadelphia Union's 3-1 Knockout Round loss to NYCFC, when the score was 2-0, Ben Sweat made contact with Alejandro Bedoya in the box as the Union captain completed a pass. 

There was no penalty given, and Bedoya took to Twitter to have his say. Suffice to say, he disagreed.

Should it have been called a penalty kick?
