Centrowitz (2:49.47), Berry (46.40), Sowinski (1:47.60) and Casey (3:56.48) all did their jobs perfectly as they crushed the old WR of 9:25.97 set by the 2008 Texas squad that included Leo Manzano. Ireland also dipped under the old WR in 9:25.37, while Kenya was a nonfactor despite a 3:52.33 anchor leg from Lawi Lalang.
An F for a rust-buster is a bit harsh.
