ARCADIA, Calif. (AP) Mrazek won the $100,000 Thor's Echo Handicap by 1 1/2 lengths Monday at Santa Anita.

Love My Bud returned $6.40 and $5.20, while Nardo was another half-length back in third and paid $4 to show.
Mrazek sat behind four dueling horses on the lead before the 3-year-old swung four-wide turning for home.
