Cameron Champ recorded a career-best nine-hole score of eight-under 28 to surge into second place after round two of the Rocket Mortgage Classic.

The 24-year-old carded five straight birdies through holes two to six and capped off the outstanding run at the Detroit Golf Club with an eagle on the par-five seventh.

The American's momentum simmered on the back nine, where he combined six pars with two bogeys and a birdie for an inward one-over 37.

The mixed bag saw him sign for a seven-under 65 and sit one shot adrift of leader Nate Lashley.

Fellow countryman Lashley maintained his grip at the top of the leaderboard, following up his career-best 63 on day one with a second-round 67.

Starting on the back nine, he carded three birdies and a bogey but remained blemish-free after the turn to overtake Champ and finish on 14 under overall.

Charles Howell III is two shots back, while JT Poston and Ryan Armour are tied in fourth a stroke further back.

Newly crowned US Open champion Gary Woodland missed the cut by three strokes after a second-round 69.
