As Houston continues to suffer from Hurricane Harvey, the Houston Rockets owner vowed to help his franchise’s city in this tough time.

Owner Leslie Alexander donated $4 million to the Hurricane Harvey Relief Fund that was started by the mayor of Houston, Sylvester Turner.

“Our hearts are heavy seeing the devastation that so many of our friends, family, and neighbors are experiencing,” reads a statement from the team. “Leslie Alexander has contributed $4 million to Mayor Sylvester Turner’s Hurricane Harvey Relief Fund in an effort to help Clutch City come back stronger than ever. Please stay safe, Houston.”

The Houston sports family has come together to help their city overcome via Texans defensive end J.J. Watt’s You Caring fundraiser. He originally had a goal of $1 million, and after hitting that goal—thanks to newly signed Rocket Chris Paul— he raised it to $1.5 million.

Houston’s baseball team got in on donating, too, as the Astros owner Jim Crane and the organization’s foundation dropped $4 million into hurricane relief efforts.

Elsewhere around the league, players like Buffalo Bill defensive end Jerry Hughes— who’s a Houston native— donated $50,000 and an additional $5,000 for every sack he makes this season.
