1) Rusney Castillo Seven Years $72.5 million
The Boston Globe called Castillo the “Biggest bust in franchise history.” Castillo’s seven year $72 million contract was the biggest ever given to an international player. Castillo made his MLB debut on September 17 and played in ten games during the remainder of 2014.
He rejoined the Red Sox on May 23, 2015. In 80 games last season, Castillo hit .253 with five home runs and 27 RBIs. He added only a .288/.359/.647 OBP/SLG/OPS slash line to that.
Castillo lasted until April 14 before the Red Sox sent him to AAA Pawtucket this season. He would be sent up and down five more times this year before the Red Sox placed him on Waivers in June.

Castillo has been in Pawtucket since his demotion. He is hitting just .262 in AAA this season. He could be one of the most expensive journeymen players over the remainder of his contract. Like Puig, the off-season will determine where Castillo plays next. Unlike Puig, Castillo hasn’t shown he can succeed at the major league level.
