The previous state record for the largest Pick 6 carryover was $275,322, reached heading into closing day of Pimlico Race Course's spring meet on June 6, 2015. A mandatory payout that day produced multiple returns of $12,518.28. ... Maryland is set to kick off its grass season with three of Saturday's 10 live races scheduled to be run over Laurel's world-class turf course.
