According to Jon Heyman of FanRag Sports, Holliday's deal is a one-year, $13 million contract.
Holliday, especially on a short-term contract, is a good fit for a Yankees team that really did not feature a power-hitting lineup. As a group, in 2016, Yankees hitters posted the fourth-worst slugging percentage and fifth-worst isolated power in the AL.
As for his contract, Holliday made right about what he was expected to. MLBTradeRumors.com projected him to earn a one-year, $10 million deal prior to the start of the offseason.
In 2016, Holliday hit .246/.322/.461 with 20 home runs and 62 RBIs over 426 plate appearances. He was worth 0.7 WAR, according to FanGraphs.
