Yankees reliever David Robertson sustained an injury to his left hamstring Wednesday against the Astros, but after icing the injury, the right-hander is confident he will be available Friday against the Athletics.
"I just kind of felt some discomfort," Robertson said, per the New York Post. "I felt at first it was my left knee, but I think it was just my hamstring. It’s just a little tight. I may have tweaked it a little bit."
