Red Sox cope with Sonny Gray's hamstring tightness as bullpen stretches in 8-6 win

Sonny Gray left with right hamstring tightness and is scheduled for an MRI; the Red Sox rallied for an 8-6 win while a heavily used bullpen covered multiple innings.

The Red Sox rallied for an 8-6 win over the Detroit Tigers after Sonny Gray left in the third inning with right hamstring tightness. Boston used several relievers to cover the middle innings and later added runs to pull ahead. Carlos Narváez reached in all four plate appearances and provided key offense. The victory splits the series and comes before three games at Fenway Park against the New York Yankees. Key facts: - Sonny Gray exited in the third inning due to right hamstring tightness and is scheduled for an MRI on Tuesday; he said he has felt similar tightness in prior seasons and did not give a definitive timeline for recovery. - The bullpen covered many innings for the third straight day, with relievers including Danny Coulombe, Zack Kelly, Jovani Moran, Greg Weissert, Garrett Whitlock and Aroldis Chapman appearing in the game. - Greg Weissert recorded three consecutive strikeouts in a ninth-inning jam and has 4 2/3 scoreless innings over his last five appearances, according to the report. - Ryan Watson allowed three runs in the ninth after returning for a second inning, and Chapman was used to close out the game. - Carlos Narváez reached in each of his four plate appearances, had a bunt that produced a throwing error, doubled to score the tying run, recorded an RBI single later and stole the second base of his major-league career. - The team drew eight walks, tying a season high, and the win marked the club's second-highest run total of the season. Summary: The win provided a positive result amid ongoing pitching concerns and gives the Red Sox a split of the series heading into their upcoming home set against the Yankees. Sonny Gray's MRI on Tuesday will clarify whether he needs time on the injured list, and the heavy recent use of the bullpen was noted as a roster issue the club may address, with Payton Tolle and other arms mentioned as possible options.
