Jockey Chris McCarron said of the beaten favorite, he didn't do anything tricky or anything like that. He just ran three jumps then took one back. I guess it's fair to say he's got a common streak in him." Gray Echelon finished third for the fourth time in nine outings this year.

Pennsbury Manor is a 4-year-old gelding bred by his owner and trained by Jack Mobberty. Pennsbury Manor returned $41.80 to win and proved the first part of a $422.60 exacta on the numbers 5 and 6.

Gerry M. Cheevers' Royal Ski, leading juvenile earner of 1976, was declared from Saturday's $100.000-added Governor's Cup because his connections do not feel he is up to the 1-1/8 miles at this time. Stable Agent Joe Monahan made the statement after Royal Ski had run a fast closing second to Rushing Man in Saturday's eighth race. Monahan further noted. "This is the best he's been since the Laurel Futurity last fall. The cooler weather does him a world of good."
