Jason Day has roared into contention at the PGA Tour's lucrative Travelers Championship despite revealing he is not even firing on all cylinders.
Australia's former world No.1 repeated his first-round 66 with another four-under-par score on Friday (Saturday AEST) to jump into outright fourth, just one stroke behind the halfway leaders.
World No.1 Scottie Scheffler (62-69), fellow American and dual major winner Justin Thomas (67-64) and Englishman Tommy Fleetwood (66-65) share the lead at nine under through 36 holes.
