WASHINGTON — Dan Butler, a former Sea Dogs catcher who made his major league debut in August, was traded Wednesday from the Boston Red Sox to the Washington Nationals for left-hander Danny Rosenbaum, who had Tommy John surgery in May.

Butler, 28, who is on Washington’s 40-man roster, hit .256 during six years in the minors with the Red Sox organization. He was at Triple-A Pawtucket for most of 2014, and appeared in seven late-season games for Boston.

Butler appeared in 21 games with the Sea Dogs in 2011, then 73 the following season. His overall batting average with Portland was .243 with six home runs.

Rosenbaum is rehabbing from his reconstructive elbow surgery. He was selected by Washington in the 22nd round of the 2009 draft and is 34-36 with a 3.12 ERA in six minor league seasons.

ORIOLES: Third baseman Manny Machado said his surgically repaired knee is OK and he’s ready for spring training.

Machado, 22, took batting practice and did running drills at the team’s spring complex in Sarasota, Florida. The Orioles were finishing a three-day mini-camp.

BLUE JAYS: Toronto claimed right-hander Matt West off waivers from Texas.

West, 26, made his major league debut last season, pitching four innings over three games for Texas. He had a 6.75 ERA and no decisions.

YANKEES: Pitcher Ivan Nova agreed to a $3.3 million, one-year contract, the same salary he earned when he missed most of the 2014 season because of a torn elbow ligament.

Nova injured his right elbow April 19 during a game against Tampa Bay and had surgery 10 days later. He’s expected to return to the Yankees’ rotation in May or June.

ROCKIES: Outfielder Drew Stubbs and right-hander Jordan Lyles avoided arbitration by agreeing to one-year contracts.

Stubbs gets $5,825,000 and Lyles receives $2,475,000.

PIRATES: Korean infielder Jung-ho Kang flew to Pittsburgh and is expected to undergo a physical Thursday. Barring a setback he will join the team by the weekend, giving them some needed depth in the middle infield.

The Pirates bid more than $5 million to negotiate with Kang and have spent the last month working out the details. Kang, 27, hit .356 with 40 home runs for the Nexen Heroes last season.
