On February 3, 2007, Invasor won his fifth successive Grade I victory in the Donn Handicap at Gulfstream Park. Coming from off the pace, he was virtually stopped when Barcola, the long-shot pacesetter, began backing up. Under jockey Fernando Jara, Invasor was forced to check. Trying to angle off the rail, he was still blocked, clipping heels with Barcola. Coming into the stretch, Invasor and Jara found the hole they needed and squeezed through, achieving a two length victory over Hesanoldsalt, ridden by Rafael Bejarano.
