Rory McIlroy walks down the fairway, Max Homa waits on the putting green.

At the halfway stage of the RBC Canadian Open, it's Cameron Champ who leads at 12-under-par, with the American carding rounds of 62 and 66 to be two shots clear.

Champ, who was isn't the field at the start of the week, sitting as an alternate, has produced two blemish-free rounds at TPC Toronto to take the 36-hole lead, with Andrew Putnam two shots back of his fellow countryman.
