Brett D'Oliveira scored his third century for Worcestershire Seconds after moving up to the role of opener in the three-day clash with Hampshire Seconds at New Road.
The all-rounder hit 102 from 154 balls with 18 fours and as Worcestershire reached 337-8 before declaring – a first innings lead of seven.
Hampshire then reached 132-4 in their second innings to set up the prospect of an interesting final day tomorrow.
D'Oliveira's previous centuries for the Seconds had both come against Warwickshire – 100 not out in 2011 and 119 not out in 2012.
Worcestershire resumed on 25-1 and D'Oliveira shared a third wicket stand of 141 with Ross Whiteley whose 93 ball 60 contained 56 in boundaries with 11 fours and two sixes.
The 22-year-old was eventually fourth out at 218 – caught at second slip – but then skipper Gareth Andrew and Alex Hepburn both scored half centuries and shared a sixth wicket stand of 79 before the declaration.
Graeme Cessford picked up two early wickets in Hampshire's second innings as they were reduced to 49-3 before Joe Gatting's unbeaten half century led a partial recovery.
