PACIFIC PALISADES, Calif. -- A two-stroke swing has put Hunter Mahan and John Merrick back into a tie at the top of the leaderboard at the Northern Trust Open.

Mahan moved to 11 under with a 23-footer at the 14 hole minutes before Merrrick made bogey at No. 13 after missing the green to the left and failing to convert a 13-footer to save par.

Charlie Beljan, Webb Simpson and Charl Schwartzel -- the latter two playing in the day's final group -- are one stroke behind at 10 under. Fredrik Jacobson and overnight leader Bill Haas are tied for sixth, another stroke behind.
