Brandt Snedeker shares lead at Pebble Beach National Pro-Am

Brandt Snedeker and Ted Potter Jnr. both top the leaderboard after day two of the Pebble Beach National Pro-Am.

The tournament, which is held across three different courses, pits professional players against amateurs over four days.

Snedeker carded a four-under-par 68 at Spyglass Hill, while fellow American Potter Jnr hit a 67 at Monterey Peninsula as the pair ended Friday on eight-under overall.

John Merrick and overnight leader Hunter Mahan will go into the third round on seven-under following their rounds of 67 and 69 respectively at Monterey.

Meanwhile, a 66 for Frederik Jacobson at Pebble Beach left the Swede on seven-under with Patrick Reed.

Scotland's Russell Knox, who started the day in the lead with Mahan, struggled on the Spyglass Hill course as a one-over-par 73 put him on five-under with five others.
