The Nationals agreed to an MLB deal with 28-year-old former Oakland A's minor league Kyle Finnegan, who has not yet made an appearance in the bigs.
Gambling on relievers with great stuff has been somewhat of a trademark of GM Mike Rizzo's tenure, as evidenced by the signings of Trevor Rosenthal, Kyle Barraclough, and Fernando Rodney last year to varying degrees of success.
Finnegan has yet to appear in an MLB game, but his track record in the minors should give Nationals fans plenty of optimism. Finnegan posted a 2.31 ERA with the Double-A Midland Rockhounds and Triple-A Las Vegas Aviators last season. Considering pitching in Las Vegas essentially akin to pitching in Coors Field on steroids, Finnegan's 2.89 ERA in Vegas looks even more impressive.
If Finnegan can master pitching in Las Vegas, than mastering Nationals Park in Washington should be no problem at all for him.
