YORK will be aiming to complete a league and cup double when they take on Dunnington in the final of the Hirepoint Plant & Tool Hire Under-13s Championship later this month.
York were put in to bat by Acomb in the cup final at Woodhouse Grange.
Several rain breaks interrupted play but York made a steady start, with Cam Hall and Matt Roberts both hitting 27 before captain Sam Wordsworth added a quick 25 not out to take his side to a competitive 97-4 by the end of their 20 overs.
Acomb were in trouble early on as Matty Scurry took 3-6 and Giles Longstaff claimed 3-18 to make inroads into the top order.
Only Jamie Thornton, with 30 not out, and Thomas Brown, who made 11, reached double figures in a total of 77-8.
In the semi-finals, York won the toss and asked hosts Sheriff Hutton Bridge to bat.
Excellent bowling from Sam Backhouse (3-14) and Scurry (2-11) restricted the home side to 62-7 off 20 overs. Only Theo Smerdon, with 19, and Cameron Head, on 12, reached double figures.
York lost opener Hall early, but Roberts (11) and Scurry (32no) steered the side towards victory.
