DEL MAR, Calif. - Polytrack, Polytrack, Polytrack. The day after the first Pacific Classic run over the new surface, it was all anyone could talk about at Del Mar. The synthetic era in Southern California obviously benefitted a horse like Student Council, who scored a 23-1 upset in the biggest race of the meet. But it likely will alter the program for Lava Man, who finished an exhausted sixth as the 6-5 favorite.
