NASCAR Sprint Cup rookie Kyle Larson will start from first place for the second time in his top-level career after heading qualifying at Pocono.
The Ganassi driver had also led the field away at Richmond in April, although on that occasion rain in qualifying meant his pole was secured via practice times.
At Pocono he fended off Penske's Joey Logano - who had been quickest in the first two qualifying segments - by 0.008 seconds to claim his first pole in a traditional session.
While most of the pole contenders took their one shot at the start of the decisive five-minute session, Logano's team-mate Brad Keselowski left it until there were just seconds to spare before making his bid, but could only manage third.
Practice pacesetter Kurt Busch secured fourth, with Jeff Gordon and Kevin Harvick - winner and polesitter respectively at Indianapolis last week - sharing row three.
Denny Hamlin took pole for the previous Pocono round in June, but narrowly missed the final qualifying cut this time.
Reigning champion Jimmie Johnson had come close to being eliminated in the first round, with a mistake and a blend line penalty hampering his early runs.
A last-gasp lap got him from 29th to 23rd among the 24 who progressed, although he only managed 17th on the grid in the end.
Roush Fenway duo Greg Biffle and Carl Edwards were the biggest names knocked out in the opening segment, with their team-mate Ricky Stenhouse Jr responsible for edging Biffle out in the final moment. Not that Stenhouse got much further, as he only qualified 23rd in part two.
Two further practice sessions follow on Saturday before the race takes place on Sunday. Rain is a danger throughout the weekend but Friday's practice and qualifying were not interrupted at all - although a heavy shower struck just minutes after pole was decided.
