Substitute Steven Craig bagged a debut brace as league-leaders Partick Thistle made it four wins from four with a convincing victory over Hamilton at Firhill.
Hamilton, with a solitary point from their opening three games, went close early on when on-loan St Johnstone midfielder Stevie 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's 18-yard shot and Jags midfielder Welsh was on hand to head home from close range.
On-loan Ross County striker Craig replaced Kris Doolan before half-time and nodded his first Jags goal 14 minutes after the break.
Lawless volleyed in his third league goal of the season after the hour mark before Craig fired in the fourth from 12 yards late on.
