In what has been a breakthrough season for the Carrutherstown handler, Jardine finally landed a big pot after a string of near-misses when Nakeeta won the Ebor at York.
At Haydock on Saturday stablemate Sepal brought up a four-timer in the race formerly known as the Old Borough Cup and on the same card Mayleaf Shine won a valuable sprint handicap.
Shrewd, who is also a decent hurdler, has not been in the best of form this summer but, as a result, has been given a chance by the handicapper.
"He'll love the ground," said Jardine.
"Because the ground's been a bit fast this season for him he's dropped down the weights a bit, but that means he's now 4lb lower than when he nearly won the Ebor last year so he should go well."
Shrewd takes on seven rivals, including Byron Flyer (Ian Williams), Penglai Pavilion (Saeed bin Suroor) and Time To Study (Mark Johnston).
