There is a $74,400 Rainbow 6 carryover Friday at Laurel Park but it is no cinch to go today as Michelle Nevin has sent in Wonderful Light, who looms a hard to beat favorite in race 7, a first-level allowance.

Wonderful Light is a lightly raced but talented 4-year-old half-brother to Nevin's now retired Grade 1-winning filly-mare sprinter By the Moon. He recorded a 102 Beyer Speed Figure winning an Aqueduct maiden race in December, and a 99 when second to Westwood in a Big A allowance in January.

Westwood came back to win a second-level optional claimer in his next start.

If Wonderful Light lays an egg, it is hard to see anyone beating the Linda Rice-trained second choice Polar Jet. He finished a closing second to Eastern Bay at this level at Laurel in his last start.

Eastern Bay returned to win a second-level optional claimer at Laurel.

The Rainbow 6 begins with conditioned $5,000 claimers in races 3 and 4, and then continues with a 3-year-old filly maiden race, a first-level optional-claiming race, and Wonderful Light's race. It concludes with a $5,000 conditioned claimer in race 8.

With possibly the exception of races 6 - the optional claimer - and 8, none of those races appear overly deep.

The 12-percent takeout pick 5, which may be a better play today than the Rainbow 6, starts in race 4.
