DULUTH — Esteban Toledo, a rookie looking for his first win on the Champions Tour, says Bernhard Langer is "one of my idols here." Toledo had a one-stroke lead over Langer and three others heading into the final round of the Greater Gwinnett Championship, and said holding off his idol and others in the final round "is possibly the greatest challenge I've ever had." Toledo, from Mexicali, Mexico, completed his first-round 68 early Saturday before shooting a 2-under 70 in the second round.
