ANAHEIM -- While Justin Masterson had a successful relief appearance in Saturday's game against the Angels, the Red Sox are being cautious with how often to use the sinkerballer.
Red Sox manager John Farrell said before Sunday's game against the Angels that his next availability will be in Tuesday's series opener against the Astros. Masterson tossed three innings in a 3-0 loss, allowing just one hit in his second relief appearance of the season. A starter to begin the year, the right-hander has a 60-pitch limit at the moment.
"That's as good as he's thrown the ball all year," Farrell said.
