Friday trading preview
- Yankees to win (50%)
- Mariners to win (58%)
Baseball returns in full with a bang, highlighted by a heavyweight coastal clash as the Los Angeles Dodgers visit the New York Yankees at 7:05 p.m. ET. It'll be Roki Sasaki (3-5, 5.33 ERA) against Gerrit Cole (3-4, 4.04). Cole hasn't been at his best since returning from his year-long injury layoff, but Sasaki is so erratic -- he hasn't logged a win since late May -- that it's hard to pick against the Yankees here.
Later in the evening, at 10:10 p.m. ET, the Seattle Mariners host the San Francisco Giants. The Mariners have fallen back to earth a bit but remain seven games over .500 at home, while the Giants are mired in a disastrous season and are 11 games under .500 on the road. Also helping our case is that Bryce Miller (4-3, 2.18) gets the ball for Seattle. He'll be opposed by Landon Roupp (6-8, 4.27). Trade on MLB, the WNBA and more with the Polymarket promo code SPORTSLINE:
