Chase Headley will not negotiate a long-term contract with the San Diego Padres during the season, the third baseman's agent confirmed Thursday. Jim Murray, Headley's agent, claimed that the Padres were informed prior to this season that Headley would not discuss an extension once the year began and his intention is to stick with that stance. The Padres have given several other players long-term deals but have held off on Headley, perhaps because they want to see if he's capable of another big season. The Padres have stated that general manager Josh Byrnes has clearance to sign Headley to a deal. Trailing 3-2 and with Headley on first base after a walk, Jesus Guzman grounded a ball to the right of the D-backs' shortstop, Cliff Pennington, who bobbled the ball briefly before throwing to second base in hopes of starting a double play. The Padres needed every one of those runs, as the D-backs got back into the game with one big swing in the top of the ninth inning, as Gerardo Parra hit a three-run home run over the fence in center field off closer Huston Street to make it a one-run game.
