Sri Lankan recruit Tharushan Iddamalgoda guided Beaconsfield off to a perfect debut back among the upper echelon of the TCL.
The newly-promoted Premier League side joined the top six clubs of the TCL following last summer's A-Reserve premiership win.
The 2019-20 season opened on Saturday with the first two rounds of the TCL Twenty20.
Iddamalgoda had been recruited from Sri Lanka Navy Sports Club primarily as a first-class legspinner, batting in the middle-order.
But the 23-year-old made an impact at the top of the order for his newest team, belting 44 off 32 balls first and then 77 off just 41 to ensure Beaconsfield won both of its two T20 clashes against ACL and Trevallyn.
The Swans set up their comfortable 41-run win after contributions from Drew Clark (26) and Bradley Sims (22*). Ian Labrooy took a tidy 3-15 off four overs to restrict ACL to 8-87.
Captain James Whiteley proved to be the mainstay for Trevallyn in reaching 6-141 at Beaconsfield after notching up 48 off 44 balls.
Beaconsfield turned to Amal Ranawaka to close out the Trevallyn innings with 4-29.
The home side cruised past the target in 12.3 overs for a nine-wicket win, while Clark smashing 45 not out off just 30 balls played second fiddle to Iddamalgoda's fast start.
Longford commenced its T20 title defence strongly with a 60-run victory at Perth.
New Tigers captain Jackson Blair paid back the faith put in from coach Josh Adams.
He opened up with 67 off 54 balls combining with Dion Blair's 48 off 43 in a match turning 88-run stand for the third wicket.
Longford finished with 6-154 that was well beyond Perth's reach, replying with 6-94.
The Demons were on the end of torrid back-to-back innings when Hadspen arrived and contained the hosts to 8-70. Beau Hills starred with the ball with 3-8 in 12 deliveries.
The Premier League champions ran down an empathic eight-wicket win in just 43 balls.
Grand final hero Thanuka Dabare shot off 30 from 13 balls and Nathan Balym knocked an unbeaten 24 to seal the Chieftains victory.
