Hannon and jockey Richard Hughes went one better when Sky Lantern landed the Coolmore Stud EBF Sprint Stakes.
The grey daughter of Red Clubs showed a willing attitude as she saw off the persistent challenge of True Verdict.
Verbal Honesty and Nandinga cut out the early running with Sky Lantern handy in third place, and when Hughes asked her for an effort two furlongs out, the 11-8 favourite went about her business in meritorious fashion as she followed up her Goodwood debut success to strike by half a length.
Hannon's son and assistant, Richard Hannon jnr, said: "She's a lovely filly and crying out for seven furlongs. We'll enter her for the Albany Stakes at Royal Ascot and see what happens.
"I was very impressed with the way she did it. The second horse came to beat her and had lots of speed, but she stuck her head out well. She improved from her first run and this was a massive step up. I don't want to say she's a Guineas filly, but she's that type of make. She's big and has lots of scope. She's not just a two-year-old."
