Phils mum after watching Pedro work out

No comment by Amaro; Jays to listen to offers for Halladay

PHILADELPHIA -- The Phillies watched Pedro Martinez throw in a workout Tuesday in the Dominican Republic.

How did it go?

Phillies general manager Ruben Amaro Jr. officially declined comment through a team spokesperson before Tuesday night's game against the Reds at Citizens Bank Park. Maybe Amaro didn't want to talk about Martinez, who seems less than likely to sign with the Phillies. Or maybe he didn't want to address the talk in Toronto that right-hander Roy Halladay could be had in a trade.

Martinez threw for a few teams last month, and the consensus was that those teams came away unimpressed.

"We are trying to explore all possible options as we try to improve our club," Amaro said about Martinez on Monday.

In other words, the Phillies seemed to be covering their bases with Tuesday's workout, which Phillies assistant to the general manager Charley Kerfield attended.

But Halladay is a different story. Blue Jays general manager J.P. Ricciardi has been telling everybody that he will listen to offers for Halladay, although they will not be proactive in trading their ace. Of course, with a talent like Halladay, there is no need to be proactive. Teams that need pitching will take care of that.

"We're not going to give the guy away," Ricciardi said Tuesday. "We'd be willing to listen. That doesn't mean we'd be willing to trade."

It would take an impressive package for the Blue Jays to trade Halladay, who has a full no-trade clause, especially because he is signed next season at $15.75 million. The Brewers gave up their top prospect, outfielder Matt LaPorta, and three other prospects last year for CC Sabathia. The Indians received Grady Sizemore, Cliff Lee and Brandon Phillips in a 2002 trade for Bartolo Colon.

The Phils would have to put together a comparable package for Halladay.

Right-handers Kyle Drabek and Jason Knapp and outfielder Dominic Brown are considered untouchable in Philadelphia's system, but a pitcher like Halladay could change that. Other top prospects like Michael Taylor, Jason Donald, Lou Marson and Carlos Carrasco are available to trade.
