NORMAN — Oklahoma’s pitching staff is in a healthy place as the regular season winds down.  OU coach Patty Gasso and pitching coach Jennifer Rocha have adopted a staff approach over the last decade for a multitude of reasons.  Not only does it make the Sooners harder to prepare for, but each pitcher should enter the postseason with more tread left on the tire by spreading the innings more evenly up and down the staff.  Last year, OU had to revert to relying on ace Sam Landry , but the staff as a whole has produced in 2026.  Landry entered the last weekend of the regular season last year, having thrown 129 1/3 innings, with Kierston Deal second on the team with 65 2/3 innings and Isabella Smith third with 51 2/3 innings.  This year, despite playing five more games, the workload has lessened.  Audrey Lowry has thrown 102 2/3 innings in 2026, with Miali Guachino at 78 1/3 innings and Sydney Berzon with 52 1/3 innings thrown.…
