KEEP AN EYE ON
The only current team to have never even appeared in a World Series, the Mariners were a win short of that feat when the Blue Jays bounced them in Game 7 of the ALCS. Reloading a talented roster includes allowing 3B Eugenio Suarez to walk and trading for INF Brendan Donovan as a piece that could move all over the infield and outfield. The 29-year-old Donovan is coming off his first All-Star campaign (.775 OPS, 10 HRs, 118 games).
Cal Raleigh’s 60-homer season set records for a catcher and a switch-hitter and led the league, while his 125 RBIs across 159 games (.948 OPS). That wasn’t good enough to Aaron Judge in AL MVP voting as Raleigh finished second, but, given his position, it’s difficult to find a better value over than the 29-year-old Raleigh.
1B Josh Naylor hit homers in nine homers in 54 games (.831 OPS) after the trade deadline and quickly re-signed in the offseason to stay in Seattle on a five-year, $92.5 million deal. The 28-year-old Canadian has two .800-plus OPS seasons and one 30-homer season so far.
