THE Warrnambool and District Cricket Association and South West Cricket endured contrasting fortunes on the second day of Melbourne Country Week.
The WDCA thrashed last year's division three winner Yarra Valley to boost their division two titleholders while South West Cricket copped a reality check in the premier provincial grade, suffering a 153-run loss to Bendigo in Kew.
But the highlight of the day was Williams' sparkling 126 for the WDCA at a wet and cold Merv Hughes Oval in Footscray.
Williams almost made more than Yarra Valley's entire batting line which struggled to post 143 overs in persistent drizzle.
Williams, captain Brett Eldridge (53) and Ben Dobson (51 not out) all got among the runs as the WDCA cruised beyond their victory total two wickets down and with 21 overs to spare.
The WDCA finished at 6-290 from its 50 overs, pocketing crucial bonus points.
The win was underpinned in the field after Yarra Valley won the toss and batted. Former WDCA skipper Ben Boyd (3-25), Nirranda's Jason Mungean (3-27), Woodford's Hank Schlaghecke (2-21) and his team mate Jake McKinnon (2-37) did the damage with the ball for the WDCA.
Across the city at Kew, South West Cricket was always under pressure in pursuit of Bendigo's 5-288 in 50 overs.
SWC bowlers shared the wickets but the innings was dominated by number four batsman Cam Taylor, who made 106 for Bendigo.
