Few jersey numbers in Houston Rockets history carry the weight of tradition quite like No. 13. Since the team tipped off in the 1967-68 season, nearly 500 players have suited up across 52 different numbers—and No. 13 has been worn by 11 of them. Today, we're spotlighting the fifth man to wear it: big man Kelvin Cato, who anchored the paint for the Rockets from 1999 to 2004.

Before making his mark in Houston, Cato was a standout at Iowa State, catching the eye of NBA scouts with his shot-blocking prowess. The Dallas Mavericks selected him 15th overall in the 1997 draft, but he was immediately traded to the Portland Trail Blazers on draft night. After two seasons in the Pacific Northwest, Cato was dealt to the Rockets in 1999—a move that would define the next chapter of his career.

During his five seasons in Houston, Cato exclusively wore No. 13, becoming a reliable presence in the frontcourt. His stat line—6.2 points, 6.2 rebounds, and 1.4 blocks per game—doesn't jump off the page, but his defensive impact was undeniable. He was the kind of big man who altered shots, grabbed boards, and did the dirty work that doesn't always show up in box scores. In 2004, his time with the Rockets came to an end when he was traded to the Orlando Magic.

For fans of retro Rockets gear, Cato's No. 13 jersey represents an era of grit and blue-collar basketball—a reminder that every number in the rafters has a story worth telling.
