The refereeing profile of Tucsonan Chris Rastatter has expanded. In addition to working Pac-12 games, Rastatter this month has officiated Big 12 games — Oklahoma State at Oklahoma and TCU at Baylor. It suggests that he’s getting closer to the Final Four than at any time. Through Thursday, Rastatter had called 36 games this season. Talk about being in demand. The only Pac-12 refs with more assignments are Dave Hall (42), Verne Harris (40), Tony Padilla (39) and Randy McCall (39). They have all officiated Final Fours.
