2018 Clemson Tiger Paw Invitational - USC Men - 4x400 Meter Relay -
The USC quartet of Zach Shinnick, Rai Benjamin, Ricky Morgan Jr., and Michael Norman ran 3:01.98 to set an NCAA Indoor Record. Although the time was also under the IAAF World Indoor Record, there were no sensors on the starting blocks, which would most likely prevent IAAF ratification. In addition, a United States team from 2006 ran 3:01.96, preventing this from being a World Best mark.
Official FAT Split Times: Shinnick (46.28), Benjamin (44.63), Morgan Jr. (45.72), Norman (45.35).
