Ever since Wally Backman was traded after the 1988 season, second base has been an unstable position. Very few second basemen in that span have been everyday starters for over three consecutive seasons.
With this being said, the Mets are hoping that they find a long-term second baseman in the recently converted Daniel Murphy.
Murphy is now the regular starter, mostly thanks to his offense. He batted .320 in 2011 and is off to a great start so far in 2012. He is a doubles hitter that gets on base a lot and provides occasional power surges. He is also very good at hitting the ball to the opposite field.
Defense is another story for Murphy. Being a natural third baseman, he was forced to play second base in order to be in the lineup every day. He has had trouble staying healthy the past two seasons, mostly due to his previous inability to turn double plays consistently.
Hopefully, he will be able to stay healthy for a full season this year and keep developing as a player.
The Mets also have two other players on their roster that can play second base. One of them is Justin Turner, who is now the Mets' utility infielder. He was basically the odd man out of the lineup, but he is still valuable to the lineup in his new role. Should Murphy get hurt once again this year, Turner would almost certainly become the new second baseman.
The other option is Ronny Cedeno, who was ultimately brought in for his defense. He has played in the ninth innings of the first three games of the season for his better defensive skills.
The Mets would be very unlikely to bring in another second baseman, but if it were to happen, it would likely be a right-handed-hitting veteran backup with some sort of power.
