Distance the question for Primo Via, Andean Moon

Primo Via and Andean Moon have both done their best racing going two turns. But they will be outside their usual comfort zone for Tuesday’s $45,000 feature at Parx Racing.

The 5-year-old Primo Via, coming off back-to-back wins going a mile, and Andean Moon, a 4-year-old filly whose most recent came last fall going a mile and 70 yards, will try to be effective in a first-level allowance for fillies and mares going 6 1/2 furlongs.

Primo Via, claimed for $8,000 in October by trainer Phil Aristone on behalf of LA Thoroughbreds, has won three times for her new connections, all in two-turn routes. Most recently, she romped by 5 3/4 lengths in a second-level allowance restricted to Pennsylvania-breds. Two starts back, Primo Via beat open company while running for a $10,500 tag.

Aristone has a good record with last-out winners returning in less than 30 days while switching from routes to sprints (6 for 15, 40 percent, with a $5.69 return on investment).

Andean Moon, claimed for $25,000 while still a maiden in April 2013, has won 4 of 9 starts since joining Keith Lebarron’s barn. Her best performance may have been when she crushed first-level statebred allowance foes by 7 1/4 lengths going a mile and 70 yards in November.

She will be making the second start of her form cycle after flashing speed to the stretch call and backing up to seventh in a six-furlong sprint two weeks ago.

Lebarron’s record second time off the layoff in dirt sprints in 14 for 62 (23 percent) over the past five years.

The best recent sprint form belongs to Conga Bella, part of an uncoupled entry for Parx leading trainer Patricia Farro. The 7-year-old Conga Bella rallied to narrowly miss at the same level and distance as Tuesday’s race and followed up that good effort by winning a seven-furlong $8,000 starter allowance.

Farro’s other horse in the race, the 5-year-old Missredhead, cuts back to a sprint for the first time since May 2013 after winning a second-level allowance for statebreds going a mile and 70 yards.
