Jimmy Walker and Jordan Spieth have ended day two of the AT&T Pebble Beach National Pro-Am with a share of the lead on nine-under par.
Rain and strong winds made life difficult for the players on Friday but Walker managed to come through his round of 69 without carding a bogey on the Spyglass Hill course.
Spieth, who was playing his second round on the Monterey Peninsula course, finished with a birdie on the 18th to record an impressive 67.
Hunter Mahan sits one shot behind the leading duo following a second round of 68 in the competition.
Andrew Loupe fell away from the top of the leaderboard on day two but his round of 73 on the difficult Pebble Beach course means that he is in contention heading into the weekend.
