Weekender features among 18 five-day entries for the Sky Bet Race To The Ebor Grand Cup at York on Saturday.
John Gosden's charge was second in the Ebor itself last season and the winner of Saturday's race is guaranteed a place in the line-up for the £1million showpiece in August.
The champion trainer also has Highgarden in the Listed contest and she improved on her final start of 2018 to win the Princess Royal Stakes at Newmarket.

Making Mirarcles was fourth there having previously spreadeagled his field when winning the Chester Cup. Bayshore Freeway ran well here on her latest outing, finishing third to Dramatic Queen in the Group Three Bronte Cup.
