Baldwin vs. Krasinski II

Last month we posted the first installment of New Era Cap's season-long ad campaign focusing on MLB rivalries and starring Yankees fan Alec Baldwin and Red Sox supporter John Krasinski.

Here is the second national TV spot debuting today of the NBC comedy duo showing off their MLB loyalties.

The spots will run during games throughout the season on ESPN, Fox, YES Network and NESN. Cable channels including Comedy Central, Adult Swim, Spike, FX, SportsNet N.Y. and others will also participate.
