Lubbock, Texas ? Ronald Ross was trying to distance himself and his Texas Tech teammates from recent back-to-back losses.

And he did it in a big way, scoring a career-high 30 points that included flawless shooting from three-point range to lead Tech to a 97-53 win over San Francisco.

“I can’t stop thinking about how we played against Ohio State and Iowa,” said Ross, who hit all four of his three-pointers. “Ever since then, I don’t want to be part of something that bad.”

In December, Ohio State beat Tech, 77-71, and the Red Raiders then lost the next game to Iowa, 83-53.

Devonne Giles also had a career high Saturday, scoring 22 points.

Tech (7-3) led most of the way and kept the Dons (8-4) well below their 74 points-per-game average. The Red Raiders steadily built their lead, which was up to 44 points three times.

Ross had 23 points in the first half, hitting 10-of-11 from the field, including three consecutive three-pointers that put the Red Raiders ahead, 37-17.

Ross’ previous career high of 25 points came in a 79-69 win over Colorado in March. Saturday, he finished 13-of-16 from the field.

Giles, whose previous career high of 20 points came in a 82-77 loss to Oklahoma State in March, also had 17 rebounds. Daryl Dora added 10 for Tech.

Texas Tech's Ronald Ross (24) pulls up short on a drive to the basket against San Francisco's Jerome Gumbs. The Red Raiders won, 97-53, Saturday in Lubbock, Texas.

Tech coach Bob Knight said his team hadn’t played much acceptable basketball in recent games.

“We had zero against Iowa,” he said. “I think from our standpoint we were able to play better, execute better than we did in a lot of the minutes I’m talking about when we didn’t play well.”

John Cox, who led the West Coast Conference in scoring coming into the game (22.2 points per game), scored 18 points. Johnny Dukes added 13 points for USF.

San Francisco struggled from the field at just 33 percent shooting, and also had to go most of the way without coach Jessie Evans.

Evans, who was hit with his second technical late in the first half and was ejected, said his team was outplayed by Tech.

“My team had a bad game tonight,” Evans said. “I thought that when your team is not competing the way you would like you take it out on the nearest person, and in this case it happened to be the official.”

Tech led 53-26 at halftime. The Red Raiders used a 14-0 run to build a 34-11 lead. Cox ended the Dons’ drought with a field goal at the 8:20 mark of the first half.
