IRWIN Racing’s Mark Winterbottom salvaged a top ten finish in a wet final race after a day of learning for Team 18 at the Sandown SuperSprint.

As rain settled over Melbourne for the duration of Sunday’s racing, large alterations were required to the Supercars to optimise the performance in wet running before they hit the track.

Starting 11th for Race 4, Winterbottom made an impressive launch in the IRWIN Commodore and climbed into the top five after the opening lap. However, Winterbottom slid wide at Dandenong Road corner on the second lap and dropped out of the top ten. Winterbottom fell as far back as 13th before recovering to 11th position at the chequered flag.

Winterbottom started sixth for Race 5 and brought the IRWIN Commodore home in 10th after a late-race pass on Andre Heimgartner.

The IRWIN Racing Commodore returns to Sandown tomorrow for the team’s official Victorian ride day, before the next event of the 2021 Repco Supercars Championship in Tasmania on April 10-11.

“In the dry we had great pace and we had a good chance at a trophy, but Sandown being Sandown, the clouds came over and the rain came down.

“It was definitely a day I wasn’t hoping for wet weather but we do race in it, simply we weren’t fast enough in the wet today.

“Overall a great weekend, a top ten finish, fifth in the points and we’ll continue to build as we go back to Symmons Plains in Tasmania for our next event.”
