Eleven days ahead of a new season, trade talk has heated up, Tigers general manager Dave Dombrowski said Thursday. The Tigers are listening, and only listening, to offers that often begin with one name: Rick Porcello.

But they have initiated nothing with respect to their 24-year-old, right-handed starter.

"I will legitimately say, 100 percent, I have not proposed a deal (involving Porcello) to one other club all spring," the Tigers president and general manager said during a conversation in his office at Joker Marchant Stadium.

Jim Bowden, a former Reds and Nationals general manager, said Thursday on Twitter the Tigers offered Porcello to the Padres for either bullpen closer Huston Street or setup man Luke Gregerson, and had been turned down by San Diego.

Dombrowski said there was no such offer.

"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 gonna happen? Most likely not."

Porcello has strung together a series of Grapefruit League games that have made him one of the bigger spring-camp stories in either league. In four starts spanning 18 innings pitched, Porcello has 18 strikeouts and zero walks. He has allowed 15 hits.

"This is the best I've ever seen him throw the baseball," Dombrowski said. "Scouts from other teams have said they've never seen him throw like this.

"Is it improved mechanics? That he's not throwing his slider? I don't know. But people forget that here you had the top pitching prospect in the game when we drafted him (2007).

"This guy's a premium pitching prospect. Premium."
