Mariners Upgrade #4 - Matt Chapman (3B)
Matt Chapman's performance to the All-Star break was exceptional. He had an .807 OPS and was an extremely effective defender as per usual. He regressed significantly in the second half, posting a .663 OPS but it's clear that he's got the tools needed to find the magic again.
He doesn't look like it, but Chapman is one of the hardest-hitting players in the sport. His average exit velocity (93.4 mph), barrel % (17.1%), and hard-hit % (56.4%) are all in the 98th percentile or higher. Specifically, his hard-hit rate was second only to Aaron Judge, beating out key names like Matt Olson and Juan Soto.
Unlike the other names on this list, Chapman also has immense defensive value. He posted five OAA and 12 DRS, the usual fielding numbers for a two-time platinum glove winner, and is also nominated for a gold glove this year.
He's ranked as the third-best free agent this offseason by MLB, behind just Cody Bellinger and Shohei Ohtani. However, it's reported that the Yankees and Mets are currently interested in him so if the Mariners want to make a move, they'd better make it fast.
