Add the Angels and Blue Jays to the list of American League teams interested in Darren Oliver. Those two clubs, plus the Red Sox and Rangers have shown interest in the veteran left-hander, according to Jon Paul Morosi of FOX Sports.
Oliver, 41, posted a 2.29 ERA with 7.8 K/9 and 1.9 BB/9 in 51 innings for the Rangers in 2011. The Jeff Frye client is one of the top left-handed relievers available in free agency. It's worth noting that the Angels signed former Rangers left-hander C.J. Wilson earlier this offseason.
The Blue Jays' interest is no surprise. They dealt Marc Rzepczynski last summer and Evan Crawford and Luis Perez are the only left-handed relievers on their 40-man roster at the moment. I'd be surprised if the team hasn't shown interest in most of the competent, available left-handers this offseason and I expect them to acquire one by Opening Day.
