The Pirates have agreed to a one-year, $6.7 million deal with first baseman Carlos Santana, a source told MLB.com. The club has not confirmed the deal.
Santana, 36, hit .202/.316/.376 with 19 home runs and a 102 wRC+ across 131 combined games with the Royals and Mariners.
Pittsburgh entered this offseason without a first baseman on the 40-man roster. With the addition of Santana, the Pirates have three first basemen on the 40-man.
In early November, the Pirates acquired Ji-Man Choi from the Rays in exchange for Minor League pitcher Jack Hartman. Earlier this week, the Pirates claimed first baseman Lewin Díaz off waivers from the Marlins.
