But a number of factors were working against Milone after the trade, including the Athletics' desire for bullpen depth after a 12-inning contest, coupled with the fact that Milone would not be available to pitch again for several days. Brad Mills, who will be replaced by Samardzija in the rotation on Sunday, gave the A's an eighth bullpen option Saturday.
Manager Bob Melvin struggled to find the right words to break the news to Milone.
"If you're in my position, what do you even say to a guy like that?" Melvin said. "He was a little bit shocked, and understandably so. But you haven't seen the last of Tommy Milone here."
"I feel terrible for him," said closer Sean Doolittle. "He's one of the most liked guys in the clubhouse. He has an unbelievable work ethic, and it was really tough when I saw him coming in here today cleaning out his locker."
Jason Hammel, also acquired in the deal with the Cubs, will likely take Milone's rotation spot for now and make his first start with the A's on Wednesday in San Francisco.
"This game is cruel sometimes," said catcher Stephen Vogt, who has made his share of trips between Triple-A and the Majors. "Tommy's earned his spot in the big leagues and I'm sure he'll be back soon."
