For 248 days, the verified Twitter account for Roy Oswalt was dormant. Then, at 9:19 p.m. Monday -- 43 minutes after Roy Halladay was yanked from another dismal outing -- Oswalt tweeted. He fired three messages to more than 30,000 followers.

"Alright everybody, this is officially roy Oswalt," he wrote. "Just a update, I haven't felt this good since 2010, I would love to come back to Philly, loved my time there, amazing fans"

Oswalt's agent, Bob Garber, confirmed Tuesday it was indeed Oswalt sending those messages.

Garber said Oswalt started using the Twitter account three days ago. He is throwing Mississippi State but has not yet reached 100 pitches. Garber has not been in contact with any teams and does not plan to sell his client until his arm is ready.

So why did Oswalt tweet?

"I don't know," Garber said. "I don't have an answer. He wants to play and he wants to pitch this year."

It's unlikely the Phillies will have any interest in Oswalt, who pitched in 17 games for Texas last season. The 35-year-old was unhappy with a demotion to the bullpen and manager Ron Washington said the righthander refused to pitch in one instance.

On Tuesday morning, Oswalt again took to Twitter.

"As a friend and fan of Halladay , and with a track record as long as his , don't count him out after 2 starts," Oswalt tweeted. "Lets clear the air ,I was asked by a Philly fan if I would come back to Philly , I answered that question, it had nothing to do with doc"

Oswalt started 35 games for the Phillies from 2010-11 with a 2.96 ERA.
