Watson impresses, Bjorn challenges as Masters

Bubba Watson continued his impressive bid for a second Masters title in three years on Friday as Thomas Bjorn became Europe’s leading contender for a first victory since 1999.

Watson was the only player in the 97-strong field to card a bogey-free round on a testing opening day at Augusta National, the left-hander’s 69 containing three birdies and 15 pars.
