Trade rumors continue to swirl around Rick Porcello, but the Tigers claim they haven't issued proposals to the Padres involving the right-hander.

Jim Bowden, citing a team source, reported on Thursday that Detroit had proposed two offers that were rejected by San Diego -- one for their closer, Huston Street, the other for reliever Luke Gregersen.

Dave Dombrowski, however, told the Detroit News he hasn't made such a proposal. In fact, he said, he hasn't proposed any Porcello deal.

"It's simply not right," Dombrowski said. "Does it mean I don't listen? No. You always listen to what people have to say. Is it going to happen? Most likely not."
