Michael Chavis, who played last season with the Portland Sea Dogs, was called up Friday to the Boston Red Sox for the first time as part of a series of roster moves.

Chavis and Tzu-Wei Lin were added to the 25-man roster, infielder Eduardo Nunez was placed on the 10-day injured list, and right-handed pitcher Erasmo Ramirez was designated for assignment.

Chavis, a 23-year-old infielder, was selected by the Red Sox in the first round of the 2014 draft. A right-handed hitter, Chavis hit .250 with four home runs, two doubles, seven walks and a .954 OPS in 12 games with Triple-A Pawtucket this season.

“We’ll find a way to get Michael at-bats,” Manager Alex Cora said. “I’m happy for the kid that he’s a big leaguer. Hopefully he can make an impact.”

Chavis played 33 games with the Sea Dogs last season after serving an 80-game suspension because of a positive test for performance-enhancing drugs. Primarily a third baseman, Chavis hit .303 with six home runs and 17 RBI for Portland before being promoted to Pawtucket.

He has seen time at first, second and third base this season. He’s expected to see most of his time at second in Boston, with Dustin Pedroia, Brock Holt and Nunez on the injured list.

Lin, who is expected to get most of the playing time at second, has appeared in 63 games with the Red Sox over the last three seasons.

THE RED SOX traded catcher Blake Swihart to Arizona along with international bonus pool space for minor league outfielder Marcus Wilson.

Swihart was designated for assignment Tuesday. He is 6 for 26 (.231) with one home run and four RBI in 12 games this season, making all six of his starts at catcher. He also has played at first base and left field.

Diamondbacks General Manager Mike Hazen worked in player development and amateur scouting with Boston when Swihart was selected in the first round of the 2011 draft. Swihart, 27, became one of the club’s top prospects, but his offensive production hasn’t matched the hype.

Wilson, 22, was a second-round pick in 2014. He has a .255 average with a .727 OPS in 391 minor-league games, including 12 this year at Double-A.

DUSTIN PEDROIA said he got good news about the irritation in his left knee that caused his return to the 10-day injured list.

Pedroia, 35, started the season on the injured list because of inflammation in his left knee and was activated April 9. He left Wednesday night’s game against the New York Yankees in the second inning and was examined Thursday, when Boston put him back on the IL.

“More kind of scared me than anything,” Pedroia said. “I was nervous, obviously, to feel that. We’re just going to let it calm down for a few days and then it should be all right. I hadn’t had any issues up until this point.”

Pedroia felt a pop when he went to rotate on a swing.

“Sometimes the batter’s box are a little tacky and things like that,” Pedroia said. “The brace I wear is strapped around, so it kind of like torqued and my knee didn’t.”

Cora originally thought the injury could be serious.

“The way he reacted that day I was like ‘oh, this is it right here,'” Cora said. “I was thinking the worst. I’m relieved. We got some positive news. Now it’s just a matter to see how he reacts during the week. When he’s ready, he’s ready.”

Pedroia will use a different type of brace when he returns.

Pedroia has appeared in six games, making four starts at second base and two as a designated hitter. He is 2 for 20 with a walk, one RBI and one run. He did not need an MRI.

“I’ve been through a lot,” Pedroia said. “It’s fun being out there playing. It was just a weird, freak thing.”
