The Cubs, continuing to rework their starting rotation, are close to signing free-agent left-hander Paul Maholm, according to a major-league source.
Maholm, 29, went 6-14 with a 3.66 ERA for the Pirates last season, ending the year on the DL with shoulder trouble. The Pirates paid him a $750,000 buyout rather than exercise his $9.75 million option.
The Cubs have dramatically overhauled their rotation this offseason, trading right-hander Carlos Zambrano for righty Chris Volstad and acquiring lefty Travis Wood in the Sean Marshall deal.
Maholm would join the group of new starters at a time when the team is still talking about trading its No. 1 pitcher, right-hander Matt Garza.
The Mariners, Red Sox, Orioles and Pirates were among the other teams that showed interest in Maholm.
The Orioles are close to signing another lefty, Wei-Yin Chen.
