The Yankees added to their treasure trove of bullpen weapons on Friday by reinstating left-hander Justin Wilson (left shoulder) from the 10-day injured list. Manager Aaron Boone said Wilson was probably “about ready” to return by Opening Day, but the team wanted to ensure he was built up properly.

“I feel really good about where he’s at physically,” Boone said of Wilson, “and there shouldn’t be any limitations.”

Wilson last appeared during a Spring Training game on March 22 against the Phillies, when he signaled to the dugout that something was wrong after tossing a pitch. He exited with tightness in his left shoulder.

The lefty reliever returns to a relief corps that leads the American League in ERA (1.00) entering Friday. The pitching staff as a whole has an MLB-best 1.74 ERA.

Wilson signed a $2.85 million deal with the Yankees in February that included a $2.3 million player option or a $7.15 million club option for the 2022 season, with a $1.15 million buyout.
