Substitute Steven Craig bagged a debut brace as league-leaders Partick made it four wins from four with a convincing 4-0 victory over Hamilton at the Firhill Stadium.
Hamilton, with a solitary point from their opening three games, went close early on when on-loan St Johnstone midfielder Steve May forced Scott Fox into a fine save.
Jackie McNamara's men then took over and edged in front four minutes before the interval through Sean Welsh.
Hamilton goalkeeper Kevin Cuthbert could only parry Steven Lawless' 18-yard shot and Jags midfielder Welsh was on hand to head home from close range.
On-loan Ross County striker Craig, who replaced Kris Doolan in the 34th minute, nodded in from six yards to double the advantage 14 minutes after the break.
Lawless volleyed in his third league goal of the season just after the hour mark before Craig fired in the fourth from 12 yards four minutes from time.
