Premier Pegasus, who earned $150,000 for his runaway victory in Saturday’s Grade II, $250,000 San Felipe at Santa Anita, jumped from No. 27 to No. 13 on the Kentucky Derby 137 Graded Stakes Earnings List. The list will likely determine the field for the “Run for the Roses” on Saturday, May 7 at Churchill Downs.

The $2 million guaranteed Kentucky Derby Presented by Yum! Brands (Grade I) has been restricted to 20 starters since 1975. Graded stakes earnings accumulated in races on the “Road to the Kentucky Derby” have determined the field for the 1 ¼-mile classic since 1986.

In other movement on the list, San Felipe runner-up Jaycito, who banked $50,000, moved up four spots into a tie for ninth with To Honor and Serve at $250,000 apiece. Comma to the Top remained at No. 5 after the $15,000 fourth-place check pushed his graded stakes earnings to $471,000.

Brethren faltered as the 1-2 favorite in Saturday’s Grade III, $350,000 Tampa Bay Derby, but added $35,000 for his third-place finish and moved from No. 21 to No. 16 with $155,000. The top-two finishers, Watch Me Go and Crimson Knight, were not among the early Triple Crown nominees, but can be made eligible for $6,000 when the late nomination period closes March 26 at midnight ET. The same goes for Joes Blazing Aaron, winner of Saturday’s Grade III, $150,000 Palm Beach over Gulfstream Park’s turf course.

Reigning 2-year-old champ Uncle Mo, ranked atop the list with $1.26 million, solidified his status as the early Kentucky Derby favorite with a 3 ¾-length win in Saturday’s $78,400 Timely Writer at Gulfstream Park, an ungraded one-mile prep for the Grade I, $750,000 Wood Memorial at Aqueduct on April 9.

In other Top 25 action, Willcox Inn, ranked No. 19 with $139,000, finished second in Saturday’s $59,400 Grindstone at 7 ½ furlongs on turf at Fair Grounds. Also, No. 21 Sweet Ducky ($120,000) is changing barns. According to The Blood-Horse’s Steve Haskin, the Holy Bull runner-up has been sold by George and Lori Hall to an anonymous buyer and will be pointed to the Group 2, $2 million UAE Derby on March 26. The Hall’s trainer Kelly Breen had been pointing Sweet Ducky to the Grade I, $1 million Florida Derby on April 3.

Three horses were removed from this week’s list. The connections of Blue Laser (No. 17 a week ago), Lou Brissie (No. 23) and Major Gain (No. 26) told Churchill Downs officials their horses were no longer under serious consideration for the Derby.
