3:11pm: MLB.com's Corey Brock writes that the Padres are seeking controllable young pitching in trades, and Gregerson is receiving the most interest from other clubs currently. Gregerson tells Brock that he's not paying attention to the rumors swirling around his name and is just "living for today" and enjoying his time with the Padres.
12:50pm: The Padres are receiving a lot of interest in Luke Gregerson, tweets Jon Heyman of CBS Sports. He adds that more teams are calling the Padres about Gregerson than they are about closer Huston Street.
That teams are more interested in Gregerson than Street isn't much of a surprise, given Gregerson's stronger numbers and cheaper price tag. While Street is earning $7MM in 2013 and again in 2014 (with a $7MM club option for 2015), Gregerson is earning just $3.2MM this season after his second year of arbitration eligibility. He will be arb-eligible once more this offseason before hitting free agency in the 2014-15 offseason.
Gregerson, 29, has a 2.98 ERA with 7.9 K/9, 1.9 BB/9 and a 46.7 percent ground-ball rate in 42 1/3 innings this season. He drew significant interest from the Tigers during Spring Training, with Detroit reportedly offering Rick Porcello in exchange for Gregerson (though GM Dave Dombrowski refuted that claim). More recent reports suggest that the Tigers are showing "continued interest" in San Diego's setup man.
