Having earned the right to host the semi, the minor premiers restricted the Chieftains to 9-181 before cantering home with three wickets and a couple of overs to spare.

Thanuka Dabare (30) and Liam Reynolds (43) formed the backbone of the visitors' innings as Dilan Sandagirigoda (2-25) and Alex Jordan (2-36) led the way with the ball for the Tigers.

After opener Jackson Blair (30) had got the ball rolling, a game-changing fourth-wicket partnership between Yeshan Wickramarachchi (40) and Sandagirigoda (48) kept the hosts in the driver's seat.

However, it was to be the tail-enders who saw them over the line despite the concerted efforts of Sameera Vishwaranga (3-34).

Hadspen's consolation will be a second chance in next week's preliminary final against ACL who finally got the better of Beaconsfield at the fifth time of asking this season.

Chathura Athukorala chose a perfect time to hit his first century of the campaign, more than doubling his previous best innings with an imperious unbeaten 133 off 117 deliveries.

Coming in at first drop, Athukorala found plenty of assistance with opener Jesse Digney smashing 58 off just 30 and Simon Chappell adding a run-a-ball 43 as ACL amassed 277 all out.

Despite the devastating display of batting, Drew Clark returned his best bowling figures of the season, as he amassed 5-27 off just five overs.

Chris Walker also chipped in with 3-64.

Clark's excellent day continued with the bat as the opener took a liking to the ACL attack.

Wickets tumbled at the other end and only an 85-run fourth-wicket partnership with Tyler Bain (36) kept the hosts' hopes alive.

Clark was the eighth wicket to fall, 11 short of his century, and Beaconsfield were bowled out in the final over, 83 runs short of their opponents.

The visiting bowlers shared the wickets around with seven claiming a scalp, led by Ian Labrooy (2-12), Kieran Davey (2-21) and Deepak Singh (2-44).
