Santa Anita Park's Rainbow Pick 6 is a mandatory-payout on Saturday, and the pool is expected to approach $6 million, providing the potential for a HUGE score. The six-race sequence begins with Race 6 at 5:45 p.m. ET and ends with Race 11. Before you make any picks, you NEED to see the picks from racing insider and accomplished horseplayer Bob Weir.

Based in Saratoga Springs, N.Y., Weir has been handicapping and following horse racing since reading Andy Beyer's landmark handicapping book "Picking Winners" in the late 1980s. Weir is highly invested in the Beyer Speed Figure, a number assigned to every race run by a horse that measures how fast the horse ran. He uses the figure as the backbone of his handicapping. In fact, thanks to his proficiency with speed figures and top-tier handicapping, he landed one of just eight spots on Beyer's figure-making team in 2017, a position he holds to this day.

Weir's methodology has produced multiple five-figure days. In 2014, he hit a $60,000 Pick 6 at Del Mar. The following year, he nailed a $31,000 Pick 6 at Gulfstream Park. In 2016 and 2017, Weir qualified for the prestigious National Horseplayers Championship in Las Vegas.

And last year, his first for SportsLine, Weir was on fire. On June 13 Weir hit a $2 superfecta in the Ogden Phipps Stakes that paid a whopping $1,039. He crushed the exacta and trifecta in the Forego Stakes in August for $1,134.50. He hit the late Pick 4 at Belmont Park on June 18, June 19, June 25, July 2 and July 5 with the June 25 score returning a whopping $2,159.50. Those are just some of his hits for SportsLine.

Anyone who has followed Weir is WAY UP.

Now, Weir has handicapped the Rainbow Pick 6 at Santa Anita for Saturday, made his picks and constructed his tickets.

We can tell you that Weir is high on Life is Good, the 4-5 favorite in the San Felipe Stakes, the opening leg of the Rainbow Pick 6. "Life is Good appears to be Bob Baffert's top 3-year-old, which means he might just end up being the top 3-year-old period," Weir tells SportsLine. Life is Good is Weir's top pick in the San Felipe and a single A horse on his Rainbow Pick 6 tickets. 

In addition, Weir is high on a double-digit long shot on Saturday! Weir says this horse "can fly late" and could light up the toteboard and spice up the Rainbow Pick 6. You NEED to see Weir's analysis before making any Rainbow Pick 6 picks!
