Tour match, Shenley: Middlesex 516-6 dec & 222-2 dec drew with Zimbabwe 401-4 dec & 221-5
Shah delivered a message to England selectors with a fine century
Zimbabwe endured a few anxious moments before comfortably keeping Middlesex at bay in the tour match at Shenley.
Set an improbable target of 338 runs to win in two sessions, the visitors were in no danger of defeat thanks to dogged knocks from Grant Flower (43 not out) and Tatenda Taibu (37 not out).
But the pair had to endure the vast majority of the evening session after three quick wickets fell following the tea break to reduce Zimbabwe to 140-5.
In all, Zimbabwe lost five wickets for 53 runs after Dion Ebrahim and Mark Vermeulen had put on 87 for the first wicket.
One of the batsmen to fall after tea was Vusimuzi Sibanda, playing his first game of the tour and bowled by Paul Weekes on his third ball faced.
Earlier, Owais Shah sent a message to the England selectors with a brilliant century.
The Middlesex batsman, overlooked for the summer one-day squad, hammered 101 not out off 80 balls.
The 24-year-old hit four sixes and 13 fours in reaching 93 not out at lunch, and moved into three figures with two more boundaries following the re-start.
The declaration then came, with Ben Hutton left on 19 not out, which included a hooked six off Sean Ervine.
Travis Friend and Mluleki Nkala came in for heavy punishment, with Shah hitting three fours in four balls off Friend in the eighth over of the day.
Only spin bowler Ray Price was able to exercise a measure of control for Zimbabwe and he picked up the only wicket of the morning session as he had Andy Strauss caught by Flower for 49.
It ended a second wicket stand of 74 between Middlesex captain Strauss and Shah, who responded by pressing down even harder on the accelerator.
