The impending end of Kyle Farnsworth?

The Yanks, yesterday, inked discarded reliever Scott Williamson to a Minor League contract. Williamson, formerly with the Orioles, was hurt for much of the season. In just 14.1 appearances spanning 16 games, he had allowed 12 hits while striking out 16 and walking 8. His ERA on the season stands at 4.40. I have to wonder if this deal is another sign that Kyle Farnsworth’s time on the Yanks is limited. The Yanks have demoted him, thanksfully, from the 8th inning role and have numerous arms to replace his in the pen.
