Aside from Kyle Tucker, Pete Alonso and Alex Bregman will be looked at as the 1A and 1B of position players on the market. While Alonso (or a replacement first baseman) is likely the New York Mets' top priority on the offensive side, Bregman would be an upgrade at the hot corner and makes sense as a worthy alternative.
The similarities between them go beyond where they are ranked on free-agent lists. Alonso is said to be seeking a seven-year deal, while Bregman rejected a six-year, $171.5 million deal from the Detroit Tigers last winter because he wanted more.
