The Other First Base Solution from San Francisco →
If the Yankees want to improve at first base, there is another player on the Giants who would be a more intriguing option. Buster Posey has been the face of the Giants franchise more or less since he was brought up to the team during the 2010 season. He has led them to three World Series victories and is a likely future Hall of Famer. However, he will be 32 years old when the 2019 season opens, may not be a full time catcher anymore and is clearly in the decline phase of his career. From 2012-2015, Posey posted an OPS+ of 145. Over the last four seasons, that number has declined to 117. That is still valuable production, but not what is needed from the middle of the order on a contending team, a role the Giants expected him to play in 2018. Moreover, Posey is owed $88.5 million over the next four years, so the Giants are stuck paying him more than what he is worth at this phase of his career.
