HOUSTON — The NCAA baseball tournament’s Houston regional was postponed Saturday after a one-hour lightning delay turned into a massive thunderstorm with rain pouring down onto Cougar Field.

Rice had just taken a 1-0 lead on Houston Baptist in the top of the fourth inning in the regional’s first elimination game. The game is scheduled to resume at 11 a.m. Sunday.

UL-Lafayette had been scheduled to play Houston in the winners’ bracket at 7 p.m. Saturday; that game is now set for 3 p.m. Sunday. The loser of that game will face the winner of the Rice/HBU game in an elimination game set to start at 8 p.m. Sunday.

Monday’s schedule also has changed. The day’s action will begin at 1 p.m., with a winner-take-all game at 6 p.m. if necessary.

On Saturday, Rice scored the day’s only run after three scoreless innings. Ford Stainback doubled to left, sliding into second base just under the tag of HBU shortstop Louie Payetta. Two batters later, Chandler knocked in Stainback on a bloop double that fell between Payetta and diving left fielder Brandon Morones.

A minute later, lightning struck, forcing players off the field and the fans out of the stadium. About an hour later, rain stormed down with tables and chairs being blown around the stadium.

The forecast for Sunday also calls for rain in Houston, which suffered from deadly storms and flooding earlier in the week.
