Clint really wasn't going anywhere without Phil chasing until Phil was unconscious or dead. It was how he did his job and right now his job was stopping Clint. At least the taser slowed him down enough that Phil could fully catch up. Running into a wall probably hurt, but getting shot would hurt more, so Phil wasn't exactly concerned.

Though it was actually a little concerning when maybe-not-Clint tried to get up and failed. "Clint?" He only had a fraction of a moment to react as the man was suddenly running at him, so he did the first thing that came to mind. He shifted his balance to the side and went in for a swift punch to the head. He just needed to keep this thing preoccupied until the guard watching the security cameras saw the fight.
