On the eve of Jim Harbaugh's second straight NFC Championship game as the 49ers coach, a horse with his same surname finished second-to-last in the $100,000 California Derby at Golden Gate Fields on Saturday.

"Better not underestimate him," Harbaugh said Friday when told the colt was listed at 10-to-1 odds to win. "He likes being underestimated."

Favored Exit Stage Left, ridden by Russell Baze and trained by Jerry Hollendorfer, held off Enterprising by a half length to win the 11/16-mile race for 3-year-olds in 1:44.07.

Harbaugh, trained by Doug O'Neill and ridden by Juan Hernandez, was bet down to 6-1 but tired down the stretch to finish seventh.

Harbaugh was making its Bay Area debut Sunday after winning two of four starts in Southern California as a 2-year-old.

The horse was born in 2011, the same year Harbaugh took over as 49ers coach. Former owners Rustin and Juliana Kretz reportedly are staunch 49ers supporters.
