Justin Rose has fired a second straight 66 to claim a share of the halfway lead alongside Tom Gillis at the US PGA Tour Honda Classic.
Gillis carded a 64 to join Rose on eight-under-par, one shot in front of Northern Ireland's Rory McIlroy.
McIlroy, who could claim the world No.1 ranking with a victory this week, had four birdies in a three-under 67.
