SEATTLE — The Red Sox have placed Justin Masterson on the 15-day disabled list with what is described as “right shoulder tendinitis.” Righthander Steven Wright will start in his place against the Seattle Mariners on Sunday.
Lefthanded reliever Robbie Ross Jr. was recalled from Triple A Pawtucket and will be available for Thursday night’s game against the Seattle.
Masterson is 2-2 with a 6.37 earned run average. After pitching fairly well in his first four starts, Masterson lasted only 6 2/3 innings in his next two games, allowing 10 earned runs on 13 hits — three of them home runs — and seven walks.
On Tuesday, Masterson gave up six runs in 2 1/3 innings against Oakland. Sox manager John Farrell suggested that night that Masterson would go on the DL. The pitcher said on Wednesday said he wasn’t happy with the decision and felt he could continue to pitch.
Wright went 5 2/3 innings in relief of Masterson on Tuesday, allowing three runs on six hits with three walks and four strikeouts.
Wright has pitched twice in the majors this season, giving up five runs over 10 2/3 innings. The knuckleballer was 2-1 with a 3.24 ERA in four starts for Triple A Pawtucket.
Wright is 2-0 in two appearances against Seattle in his career, throwing 8 2/3 scoreless innings.
