Harold Wyner has only a small stable of horses at Parx Racing, so he flies under the radar of most casual horseplayers. But pay attention when Wyner brings back a horse on short rest.\r\nWyner, whose record is a respectable 7 for 35 over the past two seasons, including 5 for 19 (26 percent) at Parx so far in 2011, does some of his best work when he brings back a sharp horse quickly. He shows a 3-for-9 record with a high $3.59 return on investment with horses coming back in 14 days or less.\r\nThose stats mean that bettors should treat Wyner&rsquo;s newly acquired Cat Park with a lot of respect in Monday&rsquo;s featured eighth race, a second-level allowance scheduled for 1 1/16 miles on turf.\r\nThe 4-year-old Cat Park, who will break from the outside in a field of eight, comes back just 10 days after he was claimed out of a win in a conditioned $25,000 claimer going 7 1/2 furlongs on the grass. His last six Beyer Speed Figures &ndash; all on turf &ndash; fall in the range of 78 to 87, which looks good at Monday&rsquo;s class level, which carries a par of 81.\r\nIn his most recent start against similar competition, Cat Park made an eight-wide move into the stretch to rally from ninth to fourth going a mile and 70 yards at Delaware Park in May.\r\nThe logical favorite is the New York-based Upgrade, a 4-year-old who has not been worse than second in his last five starts dating back to November. Upgrade, whose last five Beyers have been between 87 and 92, will be making his first start since finishing a close second at this same level in a one-mile race at Monmouth Park on May 30. The only real knock on Upgrade is that he finishes second twice as often as he wins (3 wins compared with 6 places).\r\nReprise, part of a coupled entry for trainer Mark Shuman, and Adam Suances both step up after clearing their first allowance condition last time out.\r\nThe 4-year-old Reprise was all out to prevail by three-quarters of a length going 1 1/8 miles on June 20. Adam Suances, 0 for 7 on turf while racing in Southern California, comes back quickly after winning his first start on the grass at Parx by 1 1/4 lengths on July 3.
