Procedure; Aircraft
I was working Local. Aircraft X was on a visual approach over DEPOT for RWY 27L when I observed Aircraft Y on base leg for RWY28 doing 250 knots and at the same altitude as Aircraft X and aimed right for him. Hard to turn final at that speed; so I was expecting him to slop through; which he did. He was right behind Aircraft X at the same altitude maybe 1 mile apart. I haven't seen the replay and I don't want to because it was scary enough seeing it once. I was reaching for the button to call Final when Aircraft X called me. I canceled his approach clearance and climbed him to 40 and told him to track the localizer. I final called me and I told him Aircraft X was climbing. I coordinated with a final for the go-around.Turn early to join the localizer or slow aircraft down before the turn.
