AL Wild Card Series Preview: Blue Jays vs. Mariners

While the postseason drought spanning more than two decades is over, so too is the celebration in Seattle, as the Mariners travel to the other side of the continent to face the slugging, battle-tested Blue Jays, who emerged from baseball’s best division as the top wild card.
Toronto’s lineup is dangerous from top to bottom, stacked with marquee names who have thirteen combined All Star appearances (George Springer has four of his own, Matt Chapman somehow only has one). The group had the fifth-lowest strikeout rate in baseball during the regular season, ranked third in slugging, and were second only to the Dodgers in team wRC+. Except for Raimel Tapia and Whit Merrifield, every member of the Blue Jays’ regular starting lineup posted a wRC+ over 100 on the season, and Merrifield closed the season on a .361/.385/.639 heater. If Lourdes Gurriel Jr.’s hamstring is healed in time for him to be inserted in the lineup, he’s an easy offensive upgrade on Tapia, though he may not have his timing immediately due to his lack of at-bats.
While Toronto’s lineup has undeniable star power, it may have an unexpected fault at its core. While his season, overall, was very good, Vladimir Guerrero Jr. is ice cold right now. During the last month of the season he slashed a paltry .235/.290/.390 and struggled with plate discipline. Vladdy’s chase rate during September (40%) was a full ten percentage points higher than his career norm (31%), as he struggled to lay off sliders away from him and well off the plate. Two-pitch Robbie Ray should be a great matchup for Vlad, as he doesn’t have a secondary pitch that moves away from right-handed hitters aside from an unfamiliar changeup. But the Mariners have bullpen weapons that are well-suited to exploit his recent issues in Penn Murfee, Diego Castillo, and Matt Brash, who all have sliders that finish in a spot Guerrero can’t seem to get to right now. Streaky Jays shortstop Bo Bichette has been the polar opposite, second only to Aaron Judge in WAR since the calendar flipped to September, slashing .405/.443/.664 and clubbing 19 extra-base hits during that span and entering postseason play as one of the planet’s most dangerous hitters.
