Troy Renck of the Denver Post reports that the Rockies are being "aggressive" in their pursuit of Roy Oswalt. Renck hears that the interest is mutual, but that there's "no rush" toward a resolution. The 34-year-old right-hander dealt with back problems throughout the 2011 season but still posted a 3.69 ERA and 93/39 K/BB ratio over 139 innings. He has plenty of suitors already, so the Rockies would appear to be an unlikely destination.
