Saturday is Fountain of Youth Stakes day at Gulfstream Park in South Florida, and the late Pick 4 begins with the Gulfstream Park Mile Stakes at 4:37 p.m. ET and ends with the Mac Diarmida Stakes. Before you make any picks, you NEED to know how SportsLine writer Gene Menez, who crushed the late Pick 4 on Breeders' Cup Saturday, has handicapped the sequence.

A former reporter and editor at Sports Illustrated, Menez covered an array of sports, including horse racing, for the magazine and its website for almost 14 years. Between 2010 and 2012, he served as SI's handicapper for the Triple Crown races and correctly predicted Super Saver to win the Kentucky Derby in 2010.

In 2015, while writing for Sports on Earth, Menez accurately gave out the Kentucky Derby superfecta (American Pharoah, Firing Line, Dortmund and Frosted), which paid $1,268.20 for $2. Then in 2017, he tweeted out his Kentucky Derby picks, including Always Dreaming to win, and hit the Pick 4, which paid almost $6,900 on a $1 bet.

In May of last year, Menez gave out 18-1 Mystik Dan as a live longshot in the Kentucky Derby. In November, he crushed the late Pick 4 on Breeders' Cup Saturday for a $5,303 score! And last month he hit the winner and exacta in the Holy Bull Stakes for a $422.50 payday. Anyone who followed his lead could have been way up.

For Saturday, Menez has handicapped the late Pick 4 at Gulfstream, made his picks and constructed his tickets.

We can tell you that Menez is high on Mindframe, the 1-1 favorite in the Gulfstream Park Mile, the opening leg of the Pick 4. "The layoff is a concern, but he has worked steadily for this return, and he clearly is the most talented of this bunch," Menez told SportsLine. Mindframe is Menez's top pick in the Gulfstream Park Mile and the only horse from the race on his Pick 4 tickets.

In addition, Menez is high on a longshot on Saturday. This horse is "dangerous if he gets loose" and could spice up the Pick 4. Menez is including this longshot on his tickets, and so should you. You NEED to see Menez's analysis before making any Pick 4 selections.

So which longshot can win? And how has Menez constructed his Pick 4 tickets? ...
