DENVER -- The Rockies on Monday signed power left-hander Boone Logan to a three-year, $16.5 million deal.

The Denver Post was the first to report Friday that the Rockies had moved close with Logan, 29, and CBSSports.com also reported an agreement had been reached. The club announced the contract on Monday.

Over the last four seasons with the Yankees, Logan was used more often in a specialist role. He made 256 appearances but threw 176 innings. However, the Rockies are more likely to use him as a one-inning reliever, and he would join fellow hard-throwing lefty Rex Brothers and righty LaTroy Hawkins, who signed a one-year, $2.5 million contract this winter to serve as the closer. Having Logan and Brothers from the left gives manager Walt Weiss some flexibility to close games with Brothers, who earned 19 saves last year after taking over for the injured Rafael Betancourt.

The signing means the Rockies accomplished both of the pitching priorities they set going into the Winter Meetings. They traded with the Athletics for left-hander Brett Anderson to boost their starting rotation, then made the push for Logan, who went 5-2 with a 3.23 ERA and 3.85 strikeouts per nine innings last season for the Yankees, and is 24-12 with a 4.39 ERA in 420 career appearances with the White Sox (2006-08), Braves (2009) and Yankees.

The Rockies also signed free-agent first baseman Justin Morneau to a two-year, $12.5 million deal.
