The 22-year-old, who earned the honor as the nation's top apprentice in 2002, has ridden primarily in his native Maryland and was leading rider at the recently concluded Colonial Downs meeting.
"He'll ride until the Laurel meeting ends on Aug. 22," Barsotti said. "He has seven days coming so I think he'll take them after that, come out here and ride a couple at Del Mar during the last week or so and then head to Pomona, Oak Tree, Hollywood, Santa Anita, and beyond."
Through July 31, Fogelsonger ranked third in the nation in victories with 209, 47 fewer than perennial leader Russell Baze and 37 less than Ramon Dominguez. His mounts have earned nearly $3.8 million.
"He's ready," Barsotti said. "He knows it's going to be tough but he's committed himself and I think he'll do very well out here. He's young and he's light, so it's a great time to give it a shot."
Barsotti previously booked mounts for, among others, Brice Blanc, Garrett Gomez and Mark Johnston.
