Australian Glenn McGrath, Worcestershire's pace man, produced an outstanding one man show against Warwickshire at Edgbaston.
McGrath, who is not available next summer for the New Road club, finished with impressive figures of 6-90 when Warwickshire declared at 407-7 - a first innings lead of 144.
Warwickshire decided to bat on for their maximum five batting points which they achieved in the last bonus over.
In the process they lost three wickets when Anurag Singh, Neil Smith and Alan Donald became McGrath victims.
In his 4.4 overs during the morning session his three wickets cost just ten runs.
Singh was caught at first slip by Stuart Lampitt for 46, while Smith (5) fell to a catch to Vikram Solanki at first slip and Alan Donald (16) gave wicket-keeper Steve Rhodes a catch behind.
In reply Worcestershire made a slow start with openers, Philip Weston and Elliott Wilson, putting on only 20 runs in 12 overs and at lunch were 32-0.
