The Houston Rockets continued their offseason improvements Monday, adding veteran forward Dorian Finney-Smith on a four-year, $53 million deal shortly after the NBA’s free agency window officially opened.

ESPN first reported the deal, and a person with knowledge of the agreement confirmed the terms to The Associated Press.

Houston becomes Finney-Smith’s fourth team after stints with Dallas, Brooklyn and the Los Angeles Lakers. He’ll be added to a Rockets club that earlier this summer landed Kevin Durant in a blockbuster trade with Phoenix, though that deal cannot receive formal approval from the NBA until next week.

Finney-Smith averaged 8.7 points and was a 41% shooter from 3-point range this past season.

The NBA’s free agency period officially opened at 6 p.m. Eastern time on Monday, but in actuality, was rolling long before that.

LeBron James has already opted in to a $52.6 million deal with the Los Angeles Lakers for this coming season and the Los Angeles Clippers saw James Harden decline his option in return for a new deal and a raise. There was even a surprise addition to free agency, with Portland announcing it has bought out the contract of former No. 1 pick Deandre Ayton — making him able to sign with any team he chooses.
