Hunter Mahan has withdrawn from the RBC Canadian Open after his wife went into labor.
Mahan was the tournament leader at 13 under after 36 holes and had yet to tee off for the third round Saturday.
Mahan took the lead Friday with an 8-under 64 to improve on his 5-under 67 from the first round.
His sudden departure now puts the spotlight on John Merrick, who finished the second round two strokes back of Mahan after tying the course record with a 62 at Glen Abbey Golf Course. Merrick will play alone.
Mahan's start time had initially been set for 1:30 p.m. ET before play was suspended for 80 minutes by weather. He had been rescheduled to tee off at 2:50 but never made it to the course.
