​BOSTON — The Red Sox have lost three of their last four games with their pitching staff struggling in a way it hasn’t all season. Still, the return of a healthy — and productive — Roman Anthony has been a major bright spot.Anthony had three hits including a homer in Wednesday’s loss to Seattle and is now 9-for-18 (.500) with four extra-base hits and just two strikeouts since coming off the injured list following an absence that lasted nearly four months. Some players struggle to find their timing when they return from long spans of not playing, but Anthony has hit the ground running.“He looks fantastic,” said interim manager Chad Tracy. “He looks really, really good. The at-bat quality is really, really good.”Before injuring his hand in Detroit on May 4, Anthony struggled in the first month of his first full major league season despite being healthy and putting together a productive spring training that included an impressive showing in the World Baseball Classic. He hit just .229 with one homer and a .675 OPS in 130 plate appearances before getting injured, striking out at a high clip (33 times) while struggling with swing-and-miss. The early results from his return to the majors, though, have been a completely different story. Since Sunday, Anthony has consistently hit the ball hard — and to all fields.His return to the lineup in the Bronx included a 101.6 mph ground-rule double to lead off the game and a 109 mph single. Monday brought another double (101.2 mph), a ninth-inning triple (106.5 mph), a walk and another hard-hit groundout (102.9 mph). In Tuesday’s game, he added two more singles (at 110.3 mph and 102 mph). Wednesday might have been his best overall game with two more singles and a 102.6 mph, 370-foot homer into the Green Monster seats off righty Michael Rucker.Anthony has not been surprised that his timing came back so quickly.“I always expect that of myself,” he said. “I’ve done it here before. I know what I’m capable of when I’m out there on the field. It’s just about continuing to get out there and play every day.“I’ve felt good since I’ve been back. Just feeding off the energy of the fans, my teammates and everything, it has felt good to be back.”After rushing other players — like Romy Gonzalez and Adley Rutschman — back from IL stints with quick rehab assignments earlier in the season, the Red Sox took a deliberate approach with Anthony, who spent nearly two full weeks on a minor league rehab assignment and played eight games. Despite fans clamoring for the Red Sox to rush Anthony back — perhaps at the start of last weekend’s four-game series in New York, the club slow-played bringing back both Anthony and Trevor Story.Now, the Red Sox believe their cautious approach with Anthony — and Story, who is 7-for-16 (.438) with four doubles and four strikeouts since Sunday — paid off. “I hope so,” said interim manager Chad Tracy. “There was a lot of narrative around how the
