HOUSTON — Boston's bullpen carousel continues to spin, as reliever Pat Light was called up Sunday night. Light would be the 11th different reliever to pitch for the Sox if and when he gets into a game.

Noe Ramirez and Roenis Elias were both sent down to Triple-A Pawtucket. The Sox needed to make two moves to accommodate Light and Sunday starter Henry Owens.

Light, 25, has allowed three hits and three runs over 6 2/3 innings for the PawSox this season.

"I actually didn’t think this was coming at all," Light said. "It's awesome."

A supplemental first-round pick in 2012, Light switched from the rotation to the bullpen in 2015 at Double-A Portland and had a breakout campaign. He can touch triple digits with his fastball, which he complements with a splitter that dives below the zone.

Since being promoted to Pawtucket last summer, however, he's battled control issues that had never plagued him as a starter. Light has walked 6.6 men per nine innings in Triple-A, roughly double the rate he had posted in the lower levels.

"His biggest thing is command and controlling his effort level," PawSox manager Kevin Boles said Sunday. "If he can get ahead with his fastball, it’s amazing how much different the at-bat is."

"I think it was mechanical things," Light said of the command issues in spring training. "I was rushing too much to the plate, and then you start rushing and then you think about staying back. Once you think about mechanics on the mound, you're pretty much screwed. It was more so getting my delivery down consistently so whatever the situation is I can perform."

Light has struck out 10 and walked three of the 27 batters he's faced this season. Two of those walks came in the first four batters he faced in 2016.

"My first outing was a little shaky. I didn’t really have it that day, but I was able to make some adjustments which I wasn’t able to do last year," Lught said. "That was actually a really good outing for me to come back after not having that control. From then on, it's been pretty good for me."

Light's stay in the majors might be short-lived, as the Red Sox would still like to get down to a more normal arrangement with four bench players and just seven relievers. They may try to do that once they return from Atlanta this week.
