Aldridge opted into his $22.3 million player option with the Spurs for next season and signed for an additional two years and $50 million, league sources said. Aldridge’s third year includes a partial guarantee, league sources said.

Aldridge, 32, and the Spurs have been engaged in extension talks over the past several weeks and worked toward finalizing a deal on Monday. Aldridge joined the Spurs in the summer of 2015, signing a four-year, $84.1 million free-agent deal, and was an All-Star in his first season with the team. He averaged 17.3 points and 7.3 rebounds in 72 games a season ago, partnering with Kawhi Leonard to lead the Spurs to the Western Conference finals.

Aldridge, a five-time All-Star, was drafted No. 2 overall in 2006 out of the University of Texas and spent his first nine seasons with the Portland Trail Blazers. He has averaged 19.1 points, 8.3 rebounds and one block per game in his 11-year career.
