Motivated to improve their defense and get Wilin Rosario's bat in the lineup more often, the Rockies are pursuing free-agent catcher Carlos Ruiz, according to multiple major-league sources. The Rockies also face a decision Monday on whether to pick up reliever Matt Belisle's $4.25 million option. Rockies owner Dick Monfort has identified landing an impact bat as a priority this winter. Ruiz would not be expected to help on offense as much as on defense, where Rosario has struggled. Colorado has also expressed interest in free-agent catcher Brian McCann, but he could be the highest-paid player on the market, leaving the veteran Ruiz a more realistic target. Ruiz, 34, has multiple suitors, including the Phillies, whose pitchers want him back. He makes sense for the Rockies given his playoff experience, proven ability to handle a pitching staff and steady offense. Colorado has shown a willingness to spend this offseason. It made a six-year, $63 million offer for Cuban slugger Jose Abreu, who accepted a $68 million deal from the White Sox.
