Playing on the IRT – 2019–present
Keller only played once a season on the International Racquetball Tour (IRT) until 2019. Those few appearances were at the US Open, where his best result was reaching the Round of 32, which Keller did three times.

In the 2019–20 season, he played 9 of the 10 events and finished 19th in the rankings having never made it past the Round of 16. Keller's breakthrough came in the 2021 season, as he made the semi-finals in Denver, the quarterfinals in Illinois, and the final of the 2021 US Open.

In Denver, Keller beat Samuel Murray, 15–6, 15–4, in the Round of 16, Mario Mercado in the quarterfinals, 15–13, 14–15, 11–6, before losing to fellow countryman Conrrado Moscoso in the semi-finals, 15–10, 15–14.

He's the second Bolivian to be in a US Open final after Conrrado Moscoso.

He faced Daniel de la Rosa in the final, and after losing the first game, he won game two to force a tie-breaker, which was the first time an IRT US Open final went to a breaker in its 25-year history. Unfortunately for Keller, De La Rosa won the breaker, to claim his first US Open title. He played doubles in Minneapolis with Kadim Carrasco, and they lost in the quarterfinals to Sudsy Monchik and Waselenchuk, 15–13, 15–11.
