London:Yorkshire announced on Saturday they had signed West Indies fast bowler Tino Best.
The 28-year-old took one for 12 from 14 overs in a trial match for the Tykes against arch-rivals Lancashire on their recent pre-season tour of Barbados.
Best has taken 28 Test and 13 ODI wickets, with his 221 first-class wickets coming at an average of just 26.98 runs apiece, including a career best of seven for 33.
He last played Test cricket in July 2009 with his most recent ODI appearance in September.
But his arrival at Headingley, which was due to take place this weekend, has been delayed by the disruption to international flights in and out of Europe by the ash cloud created by a volcanic eruption in Iceland.
That has placed Best's participation in Yorkshire's First Division County Championship match against Kent starting on April 21 in doubt.
"Tino was in good form on our recent Caribbean trip after he contacted us to ask whether he could net with the squad in Barbados," said Yorkshire director of cricket Martyn Moxon.
"He fitted in really well, bowled with pace and in good areas in the match he played for us over there and his bubbly personality will be an asset in the dressing room," the former England batsman added.
"I'm looking forward to seeing his bowling cause problems for our opponents and I'm sure he will be a real asset to the Yorkshire side."
