The deal will pay the 29-year old somewhere in the neighborhood of $5 million a season through 2016, though the exact amount has not yet been disclosed. San Francisco's 3-year, $13 million deal with Javier Lopez appears to have been a touchstone in negotiations. The Denver Post's Troy Renck suggested an overall haul of about $15 million.
Logan earned this deal because of his ability to get left-handed hitters out consistently. He limited opposing lefties to a .239 batting average and a .312 on-base percentage: Those numbers dropped to .222 and .299 when Logan pitched at Yankee Stadium.
He hasn't seen much success against other-siders though, allowing a .290/.375/.475 batting line in his eight-year career, and that split might drift further from his useful split against left handers in the thin air of Denver, where right-handers get even more of a boost than they do in the Bronx.
Colorado appears to be placing an emphasis on their bullpen this winter, having already signed veteran LaTroy Hawkins, who will reportedly close out games to start the season. Logan will pair nicely with Rex Brothers from the left side of the Rockies bullpen, but if he struggles against righties in the hitter-friendly confines of Coors, he could become a somewhat expensive LOOGY for a Rockies club that can't afford to misspend a dollar very often.
