During his introductory news conference as a member of the Phillies last week, Roy Halladay emphasized 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 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. "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 his final start at the 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, 32, wrote in the ad. "The memories will last a lifetime and so will my gratitude."

Halladay will have another chance to pitch in Toronto in 2010 when the Phillies visit the Blue Jays for an interleague series from June 25 to June 27.

Blue Jays president Paul Beeston told the Sun that the organization would honor Halladay in some manner during the series.

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

Martinez, 38, who was 5-1 with a 3.63 ERA for the Phillies last season, pitched for the Mets from 2005 to '08. He 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."
