David Miller became the all-time leader in earnings by a driver in harness racing history after a pair of third-place finishes to begin the Wednesday afternoon program at Miami Valley Raceway. "It means quite a bit. It is quite an accomplishment and I never would have dreamed that I'd be in this situation," Miller told the USTA's Wendy Ross in an video interview that was posted earlier on Wednesday. "It will be pretty amazing to think that I'm the leading money-winning driver ever." Miller came into the card just over $2,500 shy of John Campbell's mark of $299,892,141 and would go past that count after his drives with pacer Sweetens Cove and trotter My Next Chapter netted him $1,800 and $2,160, respectively. Making it even more memorable for Miller is that it came in his first year back as a regular in Ohio. "Twenty minutes up the road [Lebanon] is the track that I started at. To break it here is pretty sweet," he also said to Ross. ► Sign up for our FREE DRF Harness Digest Newsletter Campbell, who had held the record since he went past Herve Filion in 1987, sent a video message to Miller that was played after the milestone was reached and encouraged him to continue adding to his total. "The last few times I've seen [Campbell] he's told me to keep winning," Miller stated in the USTA interview. In addition to this achievement, Miller, who is the leading driver at Miami Valley in both victories and earnings, is closing in on the 15,000 career win milestone as he is currently at 14,897. Also of note is that Campbell reportedly has earnings in Swedish krona that when converted into U.S. dollars amounts to $165,450 that is not part of his official total that Miller passed on Wednesday. This means Campbell's unofficial bankroll is $300,057,591 combined between the two, though Miller is no doubt likely to pass that mark in the coming months. --Derick Giwner contributed to this report--
