Seattle Mariners vs Toronto Blue Jays Prediction & Picks - MLB

Prediction published on 7/4/26, 1:02 PM  by Carlos Zabala | Modified on 7/4/26 at 6:40 PM in MLB Picks

The Blue Jays took the first game of their series against the Mariners, winning 2-0. Cease struck out nine and blanked Seattle; the Jays' runs came when Giménez hit an RBI double and was later driven in by Vlad Jr. The series, a rematch of last year's AL Championship Series, continues Saturday with the Mariners listed as -170 favorites by the sportsbooks.

The Mariners' record is now 45-44, and they struck out 12 times on Friday. It appears Gilbert will start for the Mariners on Saturday. Seattle has six capable starters for a five-man rotation, so the manager has sometimes opted to pitch in pairs, using two starters back-to-back in a single game. However, this week he did expand the rotation to six to give each pitcher an extra day of rest.

The Blue Jays have a record of 42-46. After a quiet June, they've started July by winning their first two games. Their star, Vlad Jr., is currently having a cold spell at the plate; second baseman Ernie Clemente had a productive end to June, but went 0-for-4 in the series opener.
