He didn't. Just stop. Only Tobirama marked him. It was actually shown when Minato and Tobirama performed their combination technique. Tobirama marks Obito's back to replace him and Minato, so that Obito could get hit by Rasen-Shuriken + Kagutsuchi. Tobirama, once again teleports to him when he does combination attack with Naruto ( Senpo: Rasengan + Flying Raijin ).

Minato's speed is just instant. He could've easily teleported him away.
