Two $80,000 Indiana Sires Stakes finals, one for 2-year-old colt trotters and one for 3-year-old filly pacers, were featured on Saturday night's card at Hoosier Park. In the event for rookie colt trotters, 2-1 second choice Fiftydallarbill (Trace Tetrick) took the lead on the way to the 58 1/5 half and went on to win in 1:56 1/5.  Even-money favorite All On Black (John De Long), who rallied in the stretch after a dull cover trip, was second, a length and a quarter behind the winner, and early leader Skyway Torpedo (Peter Wrenn) took third. A colt by Swan For All, Fiftydallarbill is trained by William Crone for owner John Barnard.  Fiftydallarbill, who was purchased for $16,000 at the Hoosier Classic Yearling Sale, picked up his third victory from ten starts, and he has now earned $81,950.  He is out of the Royal Troubador mare CR Dixie Chick, a full sister to CR Commando ($378,602).  Fiftydallarbill paid $6.60 to win. Public choice Carol's Z Tam (Ricky Macomber Jr.) had a three-length lead with an eighth of a mile to go in the 3-year-old filly pace final, but she couldn't see it out, with Pretty Image (Dale Hiteman) using a 27 2/5 final quarter to go from sixth at the 1:23 2/5 three-quarters to first by a nose at the wire in a 1:51 4/5 performance.  70-1 shot Firstup (Ross Leonard), who was tenth at the half, was up for third, a neck back from the top two. Trainer Rodney Freese also co-owns Pretty Image, a daughter of Rockin Image, with partners Peter Karras and William Tortoriello.  Pretty Image posted her seventh career win, and she has now banked $173,650.  Sent off at 6-1, she returned $14.40 to win.
