It was the 21-year-old’s 50th league appearance for the Alex and he marked it in style with three goals to impress the watching scouts.
Steven Gillespie scored a stunner for the Robins but Maynard’s super show leaves the Robins still stuck in the relegation dogfight.
Maynard left keeper Shane Higgs helpless with a curling 14th-minute finish into the top corner from Kenny Lunt’s cross.
Gillespie levelled matters in the 66th minute with a superb piece of skill to confuse three Alex defenders before he lobbed the ball over Williams and into the net.
But two minutes later Maynard sidefooted home from eight yards out and he got the final touch to Baudet’s header to claim his hat-trick in the 76th minute.
