During his introductory press conference as a member of the Phillies last week, Roy Halladay made a point of emphasizing how much his time in Toronto meant to him and his family.

In case the Toronto fans didn't hear that, Halladay made it even more clear yesterday.

The former Blue Jays star took out a full-page ad in the Toronto Sun to thank the fans of Toronto for the 15 years he spent with the organization.

"I am sincerely grateful for the incredible support and compassion the Blue Jays fans have always shown me," Halladay wrote in the ad. "I am in awe of your overwhelming passion and devotion."

Even during Halladay's final, uncertain moments with the franchise, fan support was obviously behind the pitcher. After pitching his final start at Rogers Centre, a 5-0 shutout of Seattle on Sept. 25, fans chanted "Thank you, Roy!" as he walked off the field.

"Toronto will forever have a special place in my heart," Halladay wrote in the Toronto Sun ad. "The memories will last a lifetime and so will my gratitude."

Halladay will have another chance to pitch in Toronto during the 2010 season when the Phillies visit the Blue Jays for an interleague series on June 25-27. Blue Jays president Paul Beeston told the Sun that the organization will honor Halladay in some manner during that series.

Mets not interested in Pedro return. Contrary to a report on ESPN.com, a Mets official told the New York Daily News that the team is not interested in bringing Pedro Martinez back for another stint in Queens.

Martinez, who went 5-1 with a 3.63 ERA with the Phillies last season, pitched for the Mets from 2005-08. The 38-year-old is said to be looking for a one-year contract with a substantial raise from the $1.5 million he made with the Phillies in half a season in 2009.

Martinez has said he is interested in returning to Philadelphia, but at the winter meetings general manager Ruben Amaro Jr. said, "That's something that might develop later."
