4) Teoscar Hernandez
Teoscar Hernandez went from a guy who was traded for just Francisco Liriano to an all-star and consistently dangerous power bat. He's hit at least 22 home runs in each of the last five full seasons and even hit 16 in just 50 games during the shortened 2020 season. If he played in all 60 games for Toronto it's very possible he would've gotten to 20.
That kind of consistent power Hernandez provides would be a nice addition to this Mets lineup that outside of Pete Alonso and Francisco Lindor really lacks consistent power. This past season for the Mariners he rebounded from a slow start and slashed .258/.305/.435 with 26 home runs and 93 RBI. His August surge helped Seattle get back in the postseason race before they ultimately fell short.
Hernandez will be 31 years old when he signs his contract and is a poor defender. A big reason the Blue Jays opted to trade him outside of his expiring contract status was his outfield defense being subpar. He did make strides in the positive direction this season in that area, but his track record in the outfield isn't great.
He should get a longer-term deal than a guy like Martinez given that he's five years younger, but Teoscar being nowhere near as good of a hitter should bump the AAV down a bit to the point where he wouldn't reach $100 million.
