The forward, on loan from MK Dons, latched onto Gavin Gunning’s 16th-minute mistake and clinically finished from just inside the area. And late strikes from Marvin Morgan and sub Dean Howell wrapped up a flattering win for the hosts.
Marvin Morgan embarrassed Rotherham defender Pablo Mills to net his 14th of the season in the 82nd minute before Howell completed the scoring with a left-footed effort five minutes later.
The result severely dents the Millers’ own automatic promotion hopes but they can consider themselves hard done by.
The opener came largely against the early run of play as Craig McAllister missed the target from impressive 17-year-old debutant Abdulai Bell-Baggie’s corner.
Leading scorer Adam Le Fondre had a day to forget missing no less than four decent chances. After hitting the bar from an angled chip in the first-half, Le Fondre was repeatedly denied by Shots’ keeper Jamie Young in the second.
