Moustakas is a free agent that isn’t generating tons of buzz, but only because he’s in a free agent class with the guys mentioned above. Moustakas quietly been one of the most consistent third basemen in the league over the past few years. Last year, he hit .254 for the Brewers posting an .845 to go along with 35 home runs.
Of the three, he probably is the cheapest but his 2.8 fWAR shows he still is a valuable player. He’s in between Rendon and Donaldson age-wise having just turned 31 in September. Of the three, he also probably is the cheapest with projected deals lingering around the two or three year mark and paying under $15 million per year.
While that looks like great value and it is, for Texas, Moustakas would add yet another left-handed bat to an already overloaded lineup. If the Rangers brought in Moustakas, they would have to offload some of their left-handed bats to even make the contract worth it. A Moustakas signing would check a lot of boxes for the Rangers but feels the most unlikely unless other moves are made.
