Well, if you thought I was going to be clever with my No. 1 pick for the worst free agent signing in Mariner's history, you're probably a little disappointed by Carlos Silva making it No. 1.
The stupidity of this signing still baffles me. But then again, it was Bill Bavasi who did this, so it makes a little more sense. When the Mariners signed him to a four-year contract worth $48 million, everyone was shaking their heads. In his two previous years with the Minnesota Twins, he wasn't any good. In 2006, he had a 11-15 record and a 5.94 ERA. In 2007, he had a 13-14 record with a 4.19 ERA.
And yet, Bill Bavasi still signed him to a four-year contract worth $48 million.
In Silva's first year with the Mariners, he was downright awful: a 4-15 record with a 6.46 ERA. And he pitched half of his games in Safeco Field, a very pitcher-friendly ballpark.
In 2009, he went 1-3 with an 8.60 ERA. The Mariners eventually put him on the DL, but it's unknown if he actually suffered an injury from eating too many donuts or just for sucking way too much.
The Mariners eventually traded Silva to the Cubs for Milton Bradley, in a trade that didn't work out for either team. But the Cubs did pick up the majority of Silva's contract, so there is that.
Still, the Mariners signing Silva is undoubtedly the worst free agent singing in Mariner's history.
