Murray targets further progress
British teenager Andy Murray looks to continue his rise up the rankings this week in Aptos, California.
The 18-year-old, who has been awarded a wildcard, takes on Canadian Frederic Niemeyer on Tuesday and could then face second seed Justin Gimelstob.
The tournament is a Challenger event, a level below the ATP tour.
Murray, who reached the third round at Wimbledon on his debut, went out of last week's Newport grass-court event in the second round.
