Gloucestershire booked a C&G Trophy semi-final date with Yorkshire as they beat Middlesex by 16 runs in Bristol.

They made 239-8 in their 50 overs, with Craig Spearman top-scoring with 62 and Philip Weston adding 54.

Weston survived a run-out chance in the first over to put on 118 runs with Spearman for the first wicket.

Gloucestershire Skipper Mark Alleyne then returned 3-31 as the visitors replied with a total of 223-8 despite a half-century to Ed Joyce.

Nantie Hayward, Paul Weekes and Jamie Dalrymple all took two wickets to restrict the hosts to what looked a lowly score.

Only Shoaib Malik (43) and Martyn Ball (33 not out) made meaningful contributions after the first wicket.

But, after slumping to 28-2 and 87-4, Middlesex were never in the hunt.

Simon Cook fired a late 32 not out off 25 balls, but Alleyne took vital wickets at the death - including Lance Klusener for three - to deny the visitors.
