Some random funny Twitter reactions:
@blairbeveridge: I met Zaun on the street once. He was a prick. PED User and bad broadcaster. #strike3 Dirk who? @jparencibia9 #TeamArencibia
@simonkinglaw: If Gregg Zaun was a below average major leaguer, what the hell is JPA? #BlueJays
@LiveFromTO: Zaun and Hayhurst > JP Arencibia. Not even as baseball players, just as human beings.
@sajansz: @timandsid zaun mostly and dirk say things for reactions and are extremely polarized, therefore the deserve being called out #itgoesbothways
@markdsheldon: RT @dustinparkes if you're a catcher getting drafted in 2013, you pray to sweet Jesus that you have the career that Gregg Zaun did.
@adiction2sports: JP Arencibia is playing like crap this year. Instead of planning how to insult Zaun and Hayhurst, he should be planning how to get better.
