The Phillies have until Monday to offer salary arbitration to their four free agents: lefthander Jamie Moyer, leftfielder Pat Burrell, and relievers Tom Gordon and Rudy Seanez. Philadelphia is likely to offer Moyer arbitration. They have had serious discussions with the pitcher about a contract extension but have been unable to reach an agreement. If Moyer, 46, accepts arbitration by next Sunday's deadline, he would be a signed player for 2009.
