Josh Hader is the best reliever on the free-agent market this winter and he knows it.
Hader and his representatives are looking for the largest contract ever signed by a relief pitcher.
The current mark is held by Edwin Diaz, who signed a five-year, $102 million extension with the New York Mets.
Hader, 29, had a 1.28 ERA with 85 strikeouts and 28 walks in 56 1/3 innings this past season.
