Ricardo Vasconcelos hit a maiden List A century as Northamptonshire racked up 351 in today’s Royal London one-day Cup clash at Wantage Road, a must win game for Yorkshire.

The diminutive South African opener hit 112 off 97 balls and set the platform for his side’s 350 plus total, although Yorkshire did fight back impressively late on to limit the damage.

Should they achieve this, it will be Yorkshire’s record chase.

Vasconcelos, the left-hander, shared 118 inside 19 overs with compatriot Richard Levi (58) and 116 in 16 for the second wicket with Josh Cobb, who also made 58.

Yorkshire bowled too many boundary balls and were thus unable to apply pressure on a good pitch until late in the innings.

Josh Poysden with 2-56 from 10 overs and was the pick of the bowlers, while Mat Pillans helped restrict the damage with two wickets in the 46th over and his third in the 50th. He finished with 3-65 from 9.3.

There is no reason why Yorkshire can’t chase this down, but they have to to maintain their qualification hopes - a top three finish in the North Group.

They would then have to beat Worcestershire and Durham on Saturday and Monday.

West Indies captain Jason Holder chipped in with 36 and Adam Rossington 45 not out.
