Luis Castillo allowed a run in seven innings, Josh Naylor hit his first home run for the Mariners and Seattle beat the Athletics 3-1.

The Seattle Mariners' lineup is set as they open a three-game series against the A's in Sacramento with shortstop J.P. Crawford getting the day off.

He also just passed Mickey Mantle in baseball history, according to Sarah Langs of MLB.com:

The Seattle Mariners announced that they have selected the contract of left-handed pitcher Brandyn Garcia from their AAA affiliate, the Tacoma Rainiers, on Monday, July 21, making him the first alumnus of the Westfield Starfires to reach Major League Baseball.

Mike Salk explains how the Seattle Mariners' trade for Josh Naylor puts them in better position to make additional moves before the trade deadline.

Jorge Polanco and Cole Young hit back-to-back solo home runs in a four-run ninth inning and the Seattle Mariners beat the Detroit Tigers 8-4 to complete a three-game sweep.
