Gonzalez's string of 11 consecutive seasons with at least 150 games played came to an end last year. Back injuries limited him to a .242/.287/.355 slash line in 71 games with the Los Angeles Dodgers.
The Dodgers traded Gonzalez as part of a five-player deal to the Atlanta Braves in December. He was released two days after the deal, making him a free agent for the first time in his 14-year career.
Dominic Smith, a first-round pick in 2013, has the potential to be New York's first baseman of the future. The 22-year-old did struggle in his first taste against MLB pitching last season with a .198/.262/.395 slash line in 49 games.
Gonzalez will likely serve as insurance at first base for the Mets if they want to get Smith more Triple-A seasoning. He's no longer an All-Star at the peak of his career, but there's potential for a solid buy-low investment if his back problems are behind him.
