Teahen's a left-handed bat who knows what it's like to be an everyday player. As a Royal, he spent four seasons as a regular or semi-regular third baseman, but along the way also played some first and second base, and all three outfield positions. He's hit 13 home runs with 65 RBIs every 162 games, roughly comparable to the now-departed Laynce Nix. It's that defensive versatility, however, that made him so attractive to the Nats.
Teahen was a sandwich-round first pick of the A's in 2002, and later traded to Kansas City as part of the three-way trade that sent Carlos Beltran to Houston. He played sparingly last year for the White Sox and Blue Jays, and Toronto released him last month.
It's another low-risk, high-reward signing for Washington, who should have a far more flexible bench in 2012 than they featured last year.
