Warwickshire allowed Middlesex to recover from 252-9 to make 323 all out before themselves subsiding to 62-4 on an ebb-and-flow first day at Lord's.

Middlesex's recovery was established by Paul Weekes, who hit 92 not out after Makhaya Ntini had taken a wicket with his first ball in a Warwickshire shirt.

Ntini finished with 4-79 but Ben Hutton and Owais Shah created a platform before Weekes added the real substance.

The Bears were then rocked by Stuart Clark, the Australian taking 3-29.
