 Testing and qualifying starts this afternoon in Kent. Tonight at Seattle's T-Mobile Park, fans will be watching those hydro races on the big screen and cheering on the Mariners as they open an important three-game series with Houston. A new home series for the Everett Aqua Sox against Hillsboro tonight, and the Rainiers have Reno at Tacoma's Cheney Stadium. Both Seattle pro soccer teams on the Lumen Field pitch this weekend. Tonight you have the Rain playing Utah Royals, and then Saturday evening, the Sounders and LAFC.
