His answer was brief, but the confidence behind it was abundant. Asked if physically he was prepared for a full season as the Miami Marlins' everyday third baseman, Placido Polanco said: "Yes, sir." Polanco's one-year, $2.75 million free-agent deal sparked questions about whether he was a full or partial solution to the third-base vacancy. Due in large part to a back issue, Polanco appeared in just 90 games for the Phillies last season. Now 37, Polanco has seen his games-played total drop each of the last three years.
