3. Mets trade target Ketel Marte
Ketel Marte is one of the more underrated players in all of baseball because he has to play in Arizona on a team that just went 52-110 last season. Marte did only play 90 games last season because of injury, but in those games, he was one of the best hitters in the game. His 139 WRC+ would've led the Mets. He did this with virtually no protection in the lineup while playing for one of the worst teams in baseball in the same division as two 105+ win teams.
Marte is a guy who can hit in the middle of the order and do it all offensively. He's hit as many as 32 home runs in a season, so he has power. He's hit as many as 12 triples in a season, so he has speed. He's hit as high as .329 in a season, so he can hit for average. When right, he's one of the better players in the game.
In addition to playing for a horrible team, Marte has also had to deal with playing a position in which he is clearly not comfortable in. Marte was playing center field and had -15 DRS there last season. He's a natural middle infielder with a ton of shortstop and second base experience. Second base is where he'd play for the Mets, and he's very good there. The last season he had full-time reps at second base was in 2018 and he had 13 DRS that season, tied for third in the majors among second basemen.
The Mets would have one of the better double play combinations in the game with Marte and Lindor. Marte would give the Mets another switch hitter that they can plug in the middle of the lineup.
While second base might not be the biggest need on the roster, Marte's ceiling is too high to ignore. In the 2019 season he slashed .329/.389/.592 with 32 home runs and 92 RBI. He was an all-star and finished fourth in the National League MVP balloting. The Mets could definitely use that kind of upside.
Marte is also on an incredibly team friendly deal. He's set to make $8 million dollars this season with two club options for the two following seasons worth $10 million dollars and $12 million dollars respectively.
The 28 year old is entering his prime and will be a Met on very cheap money for the next three seasons if they acquire him now. The asking price will be astronomical, but as long as Francisco Alvarez is not included, I'd consider it. He's that kind of difference maker.
