\r\nLOUISVILLE, Ky. &ndash; Cold weather was the big story Friday morning at Churchill Downs with temperatures in the low 40s when the track opened and perhaps a few degrees lower by the time the sun dawned.\r\nDespite the fact the first of the two Breeders&rsquo; Cup cards were just one week away, workout activity was light. Only four pre-entered horses, all generally regarded as longshots in their respective races, turned in recorded drills, three coming on a fast main track and the last over a firm turf course.\r\nCash Refund (Sprint, five furlongs in 1:00.32): The racetrack was quick immediately after the renovation break, and this Sprint candidate and his work partner Home Run Bertie made it look even faster the way they motored from the half-mile pole to the wire, posting fractions of 11.40 seconds, 23.38, 34.08, and 46.42 while nearly on even terms after four furlongs. Cash Refund then continued on an extra eighth of a mile on his own while under some urging around the turn, tiring late from the effort to complete five-eighths in 1:00.32 with a six-furlong gallop out in just 1:16.40. Friday&rsquo;s work was the fourth in a series of fast drills that began at Keeneland for the multiple stakes winner Cash Refund, who figures to assure an honest pace in the Sprint.\r\nCLOCKER ARCHIVE: Find Mike Welsch's previous Breeders' Cup workout reports\r\nTidal Pool (Filly and Mare Sprint, four furlongs in 46.38): She was the first to go after the track re-opened following the break and like Cash Refund, Tidal Pool was a blur from the half-mile pole on home, cutting out splits of 11.26, 22.21, and 33.98 before tiring some coming to the wire. As we have seen in the past with all the D. Wayne Lukas-trained Kentucky Derby and Breeders&rsquo; Cup horses, there is virtually no gallop out, as Tidal Pool eased around to the seven-furlong marker in 1:02.64 for five furlongs. It was more speed than one might have expected to see from Tidal Pool, a Grade 1-placed filly who needs some help to get into the Filly and Mare Sprint from the also-eligible list.\r\nSoundwave (Juvenile Fillies, five furlongs in 1:02.88): Considered a longshot despite entering the Juvenile Fillies riding a three-race win streak, she was the only Breeders&rsquo; Cup hopeful to work under the lights prior to the break. With jockey Robby Albarado aboard, Soundwave came away from the five-furlong pole at a leisurely pace, covering her opening quarter in 26.68 and three-eighths in 38.02. Might have expected a little better than a final quarter in 24.86 considering the slow beginning, especially with her being put to pressure and under the whip a couple of times coming to the wire. Not much of a gallop-out, six furlongs in 1:17.28.\r\nMajor Gain (Juvenile Turf, six furlongs in 1:17.20 around the dogs on the turf): Like Soundwave, she too was in no hurry coming away from the pole, doing little more than galloping through an opening half-mile in 54.16 before being set down at the top of the stretch by jockey Michael Baze. But unlike Soundwave, she responded to the pressure much better, completing her closing quarter in 23.00 before galloping out another eighth around the sweeping turn in 13 and some change. Looked like a very purposeful move for a horse who figures to come running late in the Juvenile Turf.\r\nAcoma (Ladies&rsquo; Classic) was one of the horses who really caught my attention galloping this morning, giving trainer/exercise rider David Carroll about all he could handle to keep her from going faster than a two-minute clip during a long and impressive gallop. She obviously has an affinity for the local surface and has bounced back nicely from her career-best performance less than three weeks ago in the Spinster.\r\nTell a Kelly (Juvenile Fillies) was another horse I really got to watch for the first time this morning and I liked the energy she showed during a routine gallop under the lights. A good sign from a filly who has never run on dirt.\r\nCalifornia workouts\r\nTropic Storm worked six furlongs in 1:12 at Hollywood Park on Friday, but his goal for the Breeders&rsquo; Cup races next weekend remains undetermined, trainer Craig Dollase said.\r\nThird in the Grade 2 Oak Tree Mile on Oct. 9, Tropic Storm has been pre-entered in the BC Dirt Mile and Turf Sprint, with a decision expected this weekend.\r\nIn Friday&rsquo;s work, Tropic Storm worked alone and was hard held early, going the first three furlongs in 36.20 seconds and five furlongs in 59.80 seconds.\r\n&ldquo;He can get a little tough,&rdquo; Dollase said.\r\nTropic Storm was one of five California-based runners to work at Hollywood Park on Friday for the Breeders&rsquo; Cup.\r\nDollase also worked Awesome Gem six furlongs in 1:13.60 for the BC Marathon. The winner of the Hollywood Gold Cup in July, Awesome Gem worked the first three furlongs in 36.60.\r\n&ldquo;It was a good work by himself,&rdquo; Dollase said. &ldquo;He&rsquo;s not the best work horse.&rdquo;\r\nQuick Enough , claimed for $40,000 at Del Mar on Aug. 5 and the winner of the Morvich Handicap at Hollywood Park on Oct. 11, worked a half-mile in 47.40 seconds. Trainer Doug O&rsquo;Neill timed Quick Enough in 59.90 seconds for five furlongs.\r\nQuick Enough will start in the BC Turf Sprint, and could have the lead or stalk the early pace in that five furlong dash.\r\n&ldquo;The post will have a lot to do with that,&rdquo; trainer Doug O&rsquo;Neill said.\r\nBC Sprint hopeful Supreme Summit worked six furlongs in 1:11.20, the second fastest of 13 recorded works at the distance. Second in the Ancient Title Stakes on Oct. 9, Supreme Summit &ldquo;galloped out really strongly,&rdquo; trainer Mike Puype said.\r\nAt the end of the morning on turf, Eclair de Lune worked a mile in 1:39.20 on her own. She went the first six furlongs in 1:15.40 and the last quarter-mile in 23.40 seconds, according to Hollywood Park clocker Russ Hudak. Eclair de Lune will start in Friday&rsquo;s Filly and Mare Turf.\r\n&ndash; additional reporting by Steve Andersen\r\nKeeneland\r\n\r\nHarmonious, pre-entered for the Filly and Mare Turf, worked on the main track at Keeneland on Friday morning. Her official time was 1:05.80 for five furlongs.
