denotes Keeneland Sales Graduate

Fun House, the 2014 Broodmare of the Year, has produced another runner by Tapit   in Untapped, who will make her first start Sept. 16 in a one-mile maiden special weight for 2-year-old fillies at Churchill Downs.

Untapped is a full sister to 2014 champion 3-year-old filly Untapable, now retired, and the 3-year-old colt Taprize, who debuted April 23 but has not hit the board in three starts. Fun House also produced grade I winner Paddy O' Prado (El Prado).

All three siblings by Tapit are Winchell Thoroughbreds homebreds trained by Steve Asmussen.

Untapped posted a Churchill bullet Sept. 2, working five furlongs in 1:00 3/5 to rank fastest of 17 that day. The juvenile filly is the 4-1 favorite on the morning line.

Two other juvenile half sisters to grade I winners will debut Friday as well at Arlington International Racecourse going about five furlongs on the turf.

Chapeau Chic, by Hat Trick  , is out of the Joyeux Danseur mare Chic Dancer, who also produced 2015 Queen Elizabeth II Challenge Cup Stakes (gr. IT) winner Her Emmynency.

The S.D. Brillie Partnership homebred has been training on the all weather-track at the Chicagoland oval for trainer Michele Boyce.

Scott Pierce's Gorgeous in Gold, trained by Michael Stidham, is a Malibu Moon   filly out of the Seeking the Gold mare Glasgow's Gold, who also produced grade I winner Swift Temper (Giant's Causeway). Glasglow's Gold has produced six winners from seven runners, including stakes winner Croisiere (Capote).

Stidham's other entry, Princess Lu Lu, is the 4-1 morning-line choice in the race.
 

Champion Tepin went out for light training over Woodbine's newly installed Tapeta main track at 6 a.m. EDT Sept. 15 under exercise rider Jason Hoyte, after arriving from New York a little after 5 p.m. one day prior.

The oustanding turf female of 2015, known as the "Queen of the Turf," brings a seven-race win streak into the Sept. 17 Ricoh Woodbine Mile (Can-IT). She will make her Canadian debut in the one-turn turf mile, seeking her sixth grade I score for owner Robert Masterson and trainer Mark Casse.
 
"She settled in perfect, as expected," said assistant trainer Norm Casse. "That's one of the things that makes her so special. She can go and do these things and never miss a beat. She was really happy yesterday and seems really happy this morning.

"I just wanted her to go out there and warm up a little bit and show a little of that energy she's been showing at Saratoga the past month. She looked really good."
 
Hoyte was pleased to be reunited with Tepin, who will go out for light training Sept. 16 as well.
 
"It was so nice to get on her. I haven't been on her since she was a 2-year-old," he said. "I can feel it in her that she has matured a lot. It's nice to get back on her. She was nice and relaxed."
