Is there a chance Shohei eventually moves into a reliever/closer role?

He's had multiple surgeries on his arm and shoulder at this point so I am just wondering if there is ever a chance he moves into a relief type role as he gets older and the likelihood of injury increases. Or is there a bigger chance he just gives it up entirely? I know during the WBC he pitched in relief so I am wondering if it's a possibility if he stays healthy. If he gets injured I'd imagine he just stops pitching all together
