Key Donation put himself on the path to next month’s Grade 2, $500,000 Super Derby on Saturday, when he swept past dueling leaders Tensas Cold Front and Master Rick to win his stakes debut in the $100,000 Prelude at Louisiana Downs.
The Prelude was the richest of four stakes on the card, all designed as preps for Super Derby Day stakes on Sept. 8. The four races Saturday were worth a cumulative $250,000.
