Nick Tammaro is announcer and morning-line odds maker at Sam Houston Race Park. This season he has added the morning line at Keeneland. Tammaro is very familiar with Keeneland racing, having won a handicapping contest there and placing in its Grade 1 Gamble. In addition to making the line at Sam Houston, Tammaro consulted with BetMakers on setting its fixed odds for Thoroughbred racing in New Jersey. There may be no greater challenge in setting odds than the boutique meets at the historic Lexington track. Overflow fields come from every region of the world to compete for the rich purses in various divisions on turf and dirt. It will be interesting to see how Tammaro approaches such a mind-boggling task. Tammaro, 38, a contributor of handicapping content at TwinSpires, replaces long-time odds-maker Mike Battaglia, who had made the line at Keeneland since 1974. Battaglia is still the morning-line maker at the Churchill Downs Inc. owned Kentucky properties of Turfway Park and Churchill Downs Racetrack.
