Rockies rumors: Carl Pavano, Derek Lowe

The Colorado Rockies made two additions to their pitching staff over the weekend -- signing Miguel Batista and Chris Volstad to minor-league deals -- but have one or two more moves on the horizon.

The club is "aggressively pursuing" free-agent right-handers Carl Pavano and Derek Lowe as additions to the back-end of the rotation, reports Troy Renck of the Denver Post:

Even with Volstad in the fold, the Rockies are aggressively pursuing free agents Carl Pavano, a right-hander they have tried to acquire numerous times over the last few seasons, and Derek Lowe, a sinkerballer who has pitched well at Coors Field.

The Rockies would like to finalize a deal with another veteran this week.

Colorado has been tied to the sinkerballer Lowe for several weeks, but this is the first we've heard of their interest in Pavano, who is also getting calls from the Mets.

Pavano, 37, missed most of the 2012 season with a shoulder capsule injury, making just 11 starts for the Minnesota Twins in his fourth and final season with the club. The right-hander amassed an unimpressive 6.00 ERA in his 63 innings on the mound last season, but his ineffectiveness could very well have been a result of his ailing shoulder.

Lowe, 39, is looking for a club that will allow him back in to a rotation after spending the last half of 2012 working out of the bullpen in the Bronx. The veteran right-hander owns an ERA over 5.00 in his last two seasons as a starter, but his high ground-ball tendencies could help his numbers in cavernous Coors Field.
