After more than a three-and-a-half hour lighting delay on the opening day of the 2019 Pac-12 Track & Field Championships, with nine champions crowned at the conclusion of Saturday's action. Stanford’s Mackenzie Little set a record in the javelin and the USC women broke records in the 4x100-meter relay. Through seven events for the men, No. 22 nationally ranked UCLA owned the lead with 58 points, followed closely by No. 7 ranked and 12-time defending champion Oregon. (May 11, 2019)
