That's not really clear. TV came back from commercials, and the review was in progress. The issue is that it occurred at the end of the inning, and that's where the umps are inconsistent about enforcing the 30-second rule. Had it not been the third out, Anderson would have likely thrown another pitch, negating the opportunity to challenge. With the third out, the part that sucks is that everyone's in the dugout, and using BA's words, the players are in "shutdown mode."
