Narrative:
Had to do a go around at aprox 600 ft MSL due to an aircraft had not departure runway 22L at mdw. The first officer may turn final a little early, anticipating the aircraft to be rolling for takeoff as we turn final. The B737 was holding a little longer in position than anticipated the tower may been expecting us to turn a little longer final, we were about two and a half to three miles out when we turned final for runway 22L. The combination of events led us to do a go around. We did the go around/re-enter the pattern and landed.
