Kevin Tway will be hoping to follow in his father's footsteps as he takes a one-shot lead into day three of the RBC Canadian Open.
The American, whose father Bob won the same tournament at Hamilton Golf and Country Club in 2003, recovered from a bogey on the 17th to finish with a birdie on the final hole and get to 13 under in Oakville, Ontario.
South Korean Whee Kim matched Tway's second-round 65 to finish on 12 under overall and was joined in second place by American Keegan Bradley.
Bradley eagled the par-five second hole and closed on nine-under 63 following an impressive birdie-eagle-birdie-eagle finish through holes 15 to 18.
Shane Lowry is six off the pace after carding an excellent five-under 67. His notched five birdies in a flawless second round to hoist himself up the leaderboard following an opening-day 70.
Seamus Power however failed to make the weekend. The Waterford man was in touch with the leaders after a bogey-free four-under-par 68 on Thursday but he followed up with a 74 that left him two under for the tournament, two shots outside the cut.
England's Tommy Fleetwood had a disappointing day, mixing six birdies with five bogeys for a round of 71 and dropping 19 places into joint 23rd.
Day one leader Robert Garrigus moved into joint 10th on nine under following a round of 72 which included four bogeys and birdies apiece.
