The wing enjoyed a fine month which included his maiden first-team hat-trick versus Plymouth Albion and the opener as Rams returned to winning ways at Leicester Lions.
Oli took 43 per cent of the vote with back row Aaron Tull (28 per cent) finishing as runner-up.
Ben Atkins – who moved to 49 caps during the month – and centurion Max Hayman were the other players shortlisted.
Rams are back in action after a weekend off when league leaders Rotherham Titans visit Old Bath Road (3pm).
