England bowler Chris Tremlett says he had to overcome a throat infection to take four wickets on the first day of play against Australia A in Hobart.
The tourists' frontline bowling attack has been rested for the final warm-up game before the Ashes, giving a second-string quartet a chance to shine.
Tremlett returned the best figures of 4-54, while Ajmal Shahzad also impressed by grabbing three wickets. Tim Bresnan took two and Monty Panesar bowled 20 economical overs.
Tremlett needed a last-minute fitness test in order to play in the match but said that he was determined not to miss out on his long-awaited opportunity.
"I had a bit of an infection, a bit of a temperature," he said.
"But I've been waiting a long time for an opportunity, so it wasn't really going to stop me playing.
"I took a few pills and things and managed to get through the day. It would have taken a lot for me not to play."
Surrey paceman Tremlett helped reduce Australia A to 75-5 at lunch and also took two more timely wickets to limit the hosts' fightback later in the day.
His first wicket came when his bounce proved too much for opener Phil Hughes, who edged to England skipper Andrew Strauss in the slips.
Tremlett added: "When you come out to Australia and play on these wickets, you hope your attributes will play a part.
"Being 6ft 8in myself, and the others are very tall as well, that's the plan - to intimidate guys and get in their faces a little bit.
"Everyone put their hand up; everyone got a couple of wickets, apart from Monty
"But even though he didn't get a wicket, he put the pressure on and bowled really well. I think as a group, it was a very good bowling performance."
Australia Test hopefuls Usman Khawaja and Callum Ferguson both failed to make a major impact, leaving Steven Smith (59) and Steve O'Keefe (66) to lead the charge.
Smith said: "At stages, I thought England bowled a little bit too short. They didn't make me drive all that much - they probably can learn from that in the second innings.
"That's the way I play. I like to go after the short ball quite a bit, and I happened to get a few away."
