(Reuters) - Jhonattan Vegas responded admirably from a double-bogey early in his back nine to get his Canadian Open title defence off to a strong start on Thursday but British Open runnerup Matt Kuchar had to battle through dizzy spells in his opening round.

Vegas was cruising along the Glen Abbey Golf Course in Oakville, Ontario, until his hiccup at the par-four 11th but he charged home with four birdies over the next seven holes for a six-under-par 66 before the weather-hit opening round was suspended due to darkness.
