Rivera has a 13.49 ERA and a blown save in five appearances against the Rays and the Red Sox.
But while the hits are up, he has one unintentional walk and has struck out 28.
My vote is no, not worried. I think these blips are natural as Mo ages, but he’s still better than almost every other closer out there, including Jon Papelbon, who has his own issues with hits and walks. It seems like Mo as a few of these every year then you look up four weeks later and he at 1.79 and blowing people away.
But if you are worried, it’s hard to argue after seeing him walk off that mound today.
