MLB's 60-game season begins today, with Yankees @ Nats and Giants @ Dodgers. As Dave Niehaus would say, "Welcome back baseball, welcome back." The Mariners logged their final intrasquad game at T-Mobile Park. LHP Justus Sheffield dazzled on the mound, dominating four frames with eight strikeouts, while Kyle Lewis and Evan White continued their hit-happy summer camp. OF Mookie Betts agreed to a 12-year, $365 million extension with the LA Dodgers, the Blue Jays are still searching for a home stadium, and expanded playoffs are revisited. Later in the hour, Aaron Goldsmith joins 710 to discuss the M's opening series against the Astros.
