Biggest Free Agent You've Never Heard Of

The Kansas City Royals made a huge splash in this winter's free agent pool, and it's possibly one of the best signings that you've never heard of. Left handed reliever, ERA of a 2.55, batters hit a weak .218 against him last season, in 67 innings pitched over 58 appearances.
Let me introduce you to Ron Mahay, ex-Texas Ranger/Atlanta Brave reliever.
It's great to see Kansas City opening up their wallets. By also adding Jose Guillen, the Royals are starting too break away from that lovable loser label they've been wearing for the past decade or so.

According to ESPN, the Giants and Yankees also looked into signing Mahay.
