Ross Whiteley launched his fourth spell at Prospects Cricket Club with a century – but the Worcestershire all-rounder finished on the losing side.
Whiteley skippered the side in the South Australian Cricket Association Grade A encounter with Adelaide University.
But he fought a lone hand with the bat as his side were beaten by 49 runs.
Adelaide totalled 247-9 in their 50 overs after electing to bat with Whiteley bowling three overs for 14 runs as second change.
He came to the wicket at 22-1 in reply and hit 106 off 117 balls with five sixes and 13 fours – a total of 82 in boundaries.
But when he was sixth out at 171 it effectively signalled the end of Prospects hopes and they were dismissed for 198 in 43.2 overs.

The New Road all-rounder made only five after coming in at number four but his side reached their target with two balls to spare.
Wicket-keeper Joe Clarke did not get chance to bat for South Perth before the rain intervened in the Western Australian Cricket Association first grade match with Midland Guildford.
