Scott Piercy’s sole possession of the RBC Canadian Open lead didn’t last long. Paul Goydos birdied the par-3 8th hole (his 17th of the day) and Chad Campbell birdied the par-5 7th (his 16th of the day) to join Piercy at 4 under. Piercy is through 12 holes in his second round with four birdies and no bogeys. Overnight leader Kris Blanks is currently alone in fourth place. He will begin his second round on the first tee at 4:20 p.m. ET.
