15 worst Toronto Blue Jays free agent signings in franchise history

15. RHP Clay Buchholz - one year, $3M (2018-2019 offseason)

A longtime member of the rival Boston Red Sox, Buchholz came aboard the Blue Jays organization at the tail end of what had been a storied career.

After throwing a stunning no-hitter in just his second big league start, Buchholz went on to be a highly respectable member of the Sox’s rotation, going 81-61 with a 109 ERA+ in parts of 10 years. He made two All-Star Games and was a part of the 2013 World Series winning club.

After struggling mightily with the Phillies in 2017, he signed on with the Diamondbacks and did exceptionally well. In 16 starts for the 2018 D’backs, he went 7-2 with a sparkling 2.01 ERA and 209 ERA+.

This performance warranted a contract from the Blue Jays, but the deal blew up in the club’s face. In 12 starts for the 2019 Jays, Buchholz posted a 6.56 ERA, allowing 11.0 H/9 and seeing a dramatic dropoff in essentially every single relevant pitching statistic.

Buchholz represents the first of many on this list who failed to put it together as a member of the Blue Jays. Unfortunately, it only gets worse from here.
