Manawatu bowler Patel tormented Auckland batsmen yesterday with rookie Liam Dudding and fellow Bay seamer Blair Tickner taking two wickets each.

Patel, who is graduating from Victoria University in Wellington in May, is enjoying a study-free second half of the summer.
The right-arm, fast-medium bowler yesterday took 5-71 from 19 overs, including four maidens, in the absence of injured veteran Seth Rance while biding his time for some minutes on the park.
"I think that's the strength of the Stags that there's always good competition in the bowling department so you've always got to take the chances that may come," he said, believing his ability to play more consecutive games over four-day spells gave him that consistency and bowling fitness to claim scalps.
Tickner, Patel said, had assumed the mantle of senior seamer and had bowled his heart out and deserved more wickets than he got yesterday.
