The Javier Báez experiment didn't last long in Queens.Shortly after acquiring him from the Chicago Cubs, the New York Mets failed to hold on to El Mago, who chose to sign a 6-year, $140 million deal with the Detroit Tigers.The Mets reportedly offered him $125 million but the Tigers added more money, a no-trade clause, and an opt-out clause after the second year, so it was a bit of a no-brainer for him.So, now that he's gone, who could replace him? Let's take a look.3. Kris BryantFor starters, the Mets could try and make a run at one of his former teammates: Kris Bryant.Bryant is coming off a solid second half of the year with the San Francisco Giants. He can play in multiple positions in the infield and even on the outfield every now and then.He'd be a big offensive upgrade over Báez and his never-ending strikeout issues, and Jon Heyman reported that the Mets have already reached out to him. They'll face plenty of competition for his services, though.2. Carlos CorreaCarlos Correa is one of the most hated players around the league but no one can deny his talent and impact on both defense and offense.Correa isn't likely to come back to the Houston Astros and is the best shortstop in the market right now, so it won't be easy to lure him to Citi Field.According to recent reports, he turned down a 5-year, $160 million contract from the Astros a couple of weeks ago, so Steve Cohen will need to get creative or spend plenty of cash to get him.1. Trevor StoryWhile not the bonafide superstar Carlos Correa is, Trevor Story is still one of the best shortstops in the league, and a better hitter as well.Story outgrew the Colorado Rockies years ago but for reasons unknown, they refused to trade him even knowing that he would walk away in free agency.They could shift him to second base to let Francisco Lindor work his magic at shortstop and they'd have one of the best defensive middle infields in all of baseball.The Mets Need A SparkThe Mets are coming off yet another disappointing season.They made big moves at the deadline and new owner Steve Cohen proved that he wasn't afraid to spend big bucks but to no avail.Now, they hope that signing Max Scherzer to that massive 3-year, $130 million deal and having Jacob deGrom back from injury gives them the spark they need to put an end to their woes.Hopefully, the new management will finally be able to turn this team around. They have a decent core and could become a powerhouse in the National League right away.
