I Can Doosit, trained by Mark Purdon and Grant Payne, won the 4yr-old trotters' section at the Harness Jewels at Cambridge at his last start on June 5.
He won the Four-Year-Old Trotters Championship at Addington in April.
He has won seven of his 12 starts this season and finished fifth in the Rowe Cup.
Four of those wins have been at Alexandra Park, including a 2700m from a 30m handicap in March. He is off 30m tonight.
Purdon drove Buster Hanover to win the Greenlane Cup in 1995 for owner-trainer Bill Pemberton.
Springfield Hero has entered calculations after wins in two of his three starts since transferring to the Cambridge stable of Andrew and Lynn Neal.
The Neals attribute a renewal of his winning form to the addition of a nose roll and a half hopples.
Springfield Hero led for most of the way last week and ran his last mile in 1.59 and 800 in 57.2. Springfield Hero had won four races for Tony Herlihy.
Ima Gold Digger, who finished second from 40m to Springfield Hero last week, has a 10m let up in the handicap tonight.
