The Yankees have hovered around .500 for much of the first-half of the season and general manager Brian Cashman said last week that he "was ready to rock and roll" in the trade market.
With a little more than three weeks until the non-waiver trade deadline on July 31, New York made a move on Sunday, sending left-hander Vidal Nuno to Arizona for Brandon McCarthy with the hopes of bolstering its starting rotation.
"I think we're always searching to make our team better," Yankees manager Joe Girardi said. "And we'll continue to do that."
Nuno, who was originally scheduled to start Monday's series opener against the Indians, had been inconsistent all season, going 2-5 with a 5.42 ERA in 17 appearances (14 starts).
McCarthy made his final start for the D-backs last Thursday and will make his Yankees debut Wednesday. To account for Nuno's start in the opener vs. the Indians, the Yankees promoted right-hander Shane Greene from Triple-A for his first Major League start. He has thrown 13 scoreless innings over his last two starts in the Minors.
Greene made his big league debut on April 24 vs. the Red Sox, allowing three unearned runs in one-third of an inning.
"Every opportunity is an opportunity to shine and get more opportunities," Girardi said.
The Indians have not been quite sure what kind of performance they will get from right-hander Justin Masterson from start-to-start this season, but lately he has been mostly ineffective.
Masterson has been knocked around in his two last starts, allowing eight earned runs in seven innings. He has walked a team-high 53 batters in 96 innings and issued 30 walks over his last nine starts. If there's a saving grace, it's that he's been far better at home (3-1, 3.54 ERA in eight starts at Progressive Field) than on the road (1-4, 6.80 ERA in 10 starts).
Masterson has been bothered by soreness in his right knee since the second start of the season, but the Indians do not believe that has affected his performance.
"I think he actually feels OK," Indians manager Terry Francona said on Wednesday. "I think it's some command that he's going to have to fight through. I think he physically feels pretty good. ... I think he's open to working with [pitching coach Mickey Callaway] a lot. That's good. We'll fight through it together."
Yankees: Soriano designated for assignment
The Yankees designated outfielder Alfonso Soriano for assignment on Sunday.
After being acquired last June from the Cubs, Soriano helped ignite the Yankees' offense with 17 home runs and 50 RBIs. Soriano, 38, has spent parts of seven seasons in New York throughout his career and was selected to seven consecutive All-Star games from 2002-08 with the Yankees, Rangers, Nationals and Cubs.
This season, Soriano had split time in right field with Ichiro Suzuki and struggled at the plate, batting .221 with six home runs.
"It's extremely difficult, because he's been a great Yankee and a great player," manager Joe Girardi said.
Indians: Bourn placed on the disabled list
The Indians placed outfielder Michael Bourn on the 15-day disabled list as he deals with left hamstring issues stemming from the final regular season game in 2013.
The latest setback came in the eighth inning of Saturday's win over Kansas City while Bourn was trying to score from second base and felt tightness in the hamstring.
"It is [frustrating]. I've been dealing with it the whole year, pretty much off and on," Bourn said. "I guess you could say it's part of the process. I just have to continue to try to get it strong, get it healthy and just be able to come back when I'm ready."
The Indians selected the contract of rookie outfielder Tyler Holt from Triple-A Columbus to replace Bourn.
• Nyjer Morgan remains on the 60-day disabled list with a sprained posterior cruciate ligament in his right knee. The outfielder has been rehabbing at the team's complex in Goodyear, Ariz., for the past two weeks.
• After taking batting practice Sunday morning, Brian McCann (sore right foot) was back in the Yankees' lineup vs. the Twins and ripped an RBI double in his first at-bat.
Girardi said McCann's MRI results came back "very good," paving the way for the catcher's return.
