OAKLAND, Calif. -

Left-hander Tommy Milone had won a career-high six straight decisions when the A's optioned him to Triple-A Sacramento on July 5 after acquiring right-handers Jeff Samardzija and Jason Hammel from the Chicago Cubs.

The demotion, apparently, did not sit well with Milone. According to multiple reports, Milone has asked to be traded.

Manager Bob Melvin said Milone called him Monday after news broke of his request.

"I'm pretty sure he didn't expect it to get the play that it has," Melvin said Tuesday before the A's 3-2, 12-inning loss against Houston. "To an extent, he's looking out for his big league career. He's pitched really well for us. I don't blame him for wanting to pitch in the big leagues.

"It doesn't mean he doesn't want to be here, and he does want to be here. He's well thought of by his teammates, well respected by his teammates. And he respects the situation going on here, but he wants to be in the big leagues, and I don't blame him for that."

The A's were able to send Milone to Sacramento because he's not out of options. He provides the A's a huge pitching insurance policy, especially with Hammel struggling in his first two starts with Oakland.

Is there any chance Milone will soften his stance?

"I don't think there's any softening to it," Melvin said. "He wants to pitch in the big leagues. He'd much rather do it here. When you've had the type of success that he's had and you're pitching in the minor leagues, that's not somewhere he wants to be."
