Atlantic Six Racing’s millionaire sprinter Book’em Danno is back at Saratoga, aiming for another big score in Saturday’s Grade 2, $400,000 Alfred G. Vanderbilt, a six-furlong test for older horses.

Trained by Derek Ryan, the New Jersey-bred son of Bucchero enters off a sharp win in the Grade 3 True North, where he rallied past Mullikin to score by 1 1/4 lengths in 1:14.64, earning a 102 Beyer Speed Figure.

That race was also at Saratoga, during the Belmont Stakes racing festival. Book’em Danno is 2-for-2 at the Spa and earned his biggest triumph there last summer, when he scored in the Grade 1 Woody Stephens.

“Everything is going good and he’s training great,” Ryan said in a release. “This is a little short for him, but he’s doing good and Paco knows him now.”

Jockey Paco Lopez has ridden him in his last three starts and retains the mount from post 5. Ryan praised Lopez’s persistence, noting, ““He’s [Lopez] been hard on me to ride him all winter and he even took a day off to come and work him at Tampa one Sunday morning, so I said, ‘Well, if he wants to ride him that bad, we’ll put him on him!’”

Book’em Danno boasts a 14-8-3-1 record and more than $1.3 million in earnings. He kicked off his 2025 campaign with a win in a Virginia-restricted handicap at Colonial Downs; Book’em Danno is Virginia certified.

He then registered a neck fourth in the Grade 1 Churchill Downs on May 3 in a four-way blanket finish between the victorious Mindframe and the dead-heating runners-up Banishing and Nysos. Mindframe won the Grade 1 Stephen Foster next out, while Nysos and Book’em Danno also returned to score.

Book’em Danno broke his maiden at first asking as a two-year-old at Monmouth Park in 2023. He won his first three starts, two in stakes company, before finishing second in the Nashua, his first defeat.

“He’s a nice, correct, sound horse,” Ryan said. “He’s just a runner. He’s a freak.”
