The decision, however, is up to Los Angeles Dodgers skipper Dave Roberts, who might choose to hand the starting nod to Washington ace Max Scherzer with the game being played in front of his home crowd at Nationals Park. Callaway believes this would be the wrong move.
"(DeGrom) should be starting the All-Star Game, that is how I feel about it,” Callaway said after deGrom tossed eight scoreless innings against the Phillies on Wednesday, according to the New York Post's Mike Puma. "There is no doubt in my mind. If he's not (starting), that is the wrong decision."
Callaway's petition for deGrom to start the Midsummer Classic holds water, too.
The 30-year-old right-hander owns an MLB-best 1.68 ERA in 123.1 innings, but Scherzer is in the midst of another dominant campaign himself.
Would deGrom accept the nod and potentially upset the fans of a division rival in Washington if he were offered it?
"Of course I would like to start it, but we'll just see what happens," he said.
