Texas Christian won the 800-meter relay at the 92nd annual Penn Relays in a world-best time of 1 minute 20.20 seconds Saturday in Philadelphia.
The quartet of Roscoe Tatum, Andrew Smith, Leroy Reid and Greg Scholars surpassed the record of 1:20.26 set in 1978 by USC at Tempe, Ariz.
The time is not a world record because Reid and Smith are Jamaicans, and all members of a team must be from the same country for a world mark.
The Horned Frogs also won the 400-meter relay in 39.11, a meet record.
Defending champion Arkansas, with Gary Taylor running 3:35.5 on the third 1,500-meter leg, took the 6,000-meter relay in 14:55.30.
Seton Hall won the sprint medley relay in 3:13.67 as Akanni Gbadamost ran his 800-meter leg in 1:46.4.
In the high school 1,600-meter relay, William Reed of Philadelphia Central ran his leg in 45.10 seconds, the fastest high school split ever recorded at the Penn Relays, in leading his team to a 3:13.9 victory.
