McPherrin was on hand for the epic 16 inning long sixth game of the 1986 National League Championship Series between the New York Mets and Houston Astros (which was broadcast on ABC).
As such, McPherrin would provide play-by-play while Monday Night Football's Frank Gifford and Lynn Swann would serve as his color commentators.
He remained in that role until 1995, when he was bumped from being WBBM's lead sports anchor by the arrival of Tim Weigel.
McPherrin then chose to leave WBBM-TV and join WFLD-TV in Chicago as its lead sports anchor.
He appeared with former Chicago Bears player Tom Waddle on The Final Word, a weekly sports review segment.
