The Pittsburgh Pirates and New York Yankees have completed the July trade that sent Ivan Nova to the National League.

New York will receive outfielder Tito Polo and left-hander Stephen Tarpley.

Nova has a 2.87 ERA over 31.1 innings since the trade, striking out 22 and walking just one.

The Pittsburgh Pirates have placed Gerrit Cole on the disabled list, retroactive to Aug. 25, with "posterior inflammation of the right elbow."

Pittsburgh called up left-hander Steven Brault from Triple-A Indianapolis to assume Cole's spot against the Chicago Cubs on Monday night. He lasted just four innings, striking out four batters and allowed two runs.

The Seattle Mariners bolstered their bullpen by acquiring right-hander Arquimedes Caminero from Pittsburgh and switch-pitcher Pat Venditte from Toronto in a pair of trades Saturday.

Both deals Seattle made were for players to be named later. Seattle will be sending two players to Pittsburgh for Caminero and one to Toronto for Venditte. The Mariners announced Venditte would report to Triple-A Tacoma, while Caminero will report to Seattle.

The Pittsburgh Pirates are sitting Andrew McCutchen from Tuesday through Thursday in hopes that the rest will help him battle out of a slump.

McCutchen says he's OK with Clint Hurdle's decision even if he doesn't agree with it.

"I have to first address myself before I can think about addressing anything else," McCutchen said. "I know if I was going out and playing the best ball that I know I can play that I wouldn't be in this position.

"They wouldn't be in the position of having to make those decisions, either."

In 97 games this year, McCutchen has a .241 average and is on pace for a career high in strikeouts.

Hurdle made the decision after watching the outfielder go 1-for-12 in a three-game series last weekend at Milwaukee.

"He's tried a lot of things," Hurdle said. "This man's fought, shown up, done early work, late work, side work, video work. In situations like this where I've seen it happen with good players, you just unplug 'em. The manager's got to do it. I'm just asking him to sign off on it.

"He obviously has a lot of fight in him and wants to continue. But it's like hitting refresh button."

The Pittsburgh Pirates will acquire Ivan Nova from the New York Yankees for a player to be named later.

Nova, 29, has a 4.90 ERA, 5.09 FIP and 75 strikeouts in 97.1 innings this season.
