Hudson Swafford and Boo Weekley will share the lead heading into day three at the Zurich Classic of New Orleans.
The 27-year-old, who is still searching for his first victory on the US PGA Tour, followed up his first round of 66 by carding a 67 at TPC Louisiana to take the clubhouse lead.
In reasonable scoring conditions, Swafford found three birdies on the front nine before further birdies at 11, 15 and 16 saw the Floridian finish the day on 11-under-par alongside first-round leader Weekley.
Weekley's own round was curtailed due to storms at the Avondale course, and the 2008 Ryder Cup player has three holes to complete on Saturday before reaching the halfway stage in the tournament.
A group of five players are one shot back on 10-under, including Australian Jason Day, Jerry Kelly and Brendon de Jonge.
