Second base is by far the biggest question mark perhaps on the entire roster entering this season. There are some other issues, such as replacing Johan Santana to begin the year as a starter or the bullpen, but this position is very important for a team.
It looks like there will be two guys battling it out in the spring for the job. Those guys are Luis Castillo and Daniel Murphy.
Do you remember Daniel Murphy? The guy who came up in the middle of 2008 and looked like the next coming of Pete Rose or Don Mattingly?
Well, after not panning out in the outfield and playing an average first base in 2009, he missed all of 2010 with some injuries. He got hurt towards the end of spring training and suffered a MCL tear in a minor league game during the season, thanks to a nasty slide by an opposing player while Murphy was playing second base.
The Mets are hoping to get him at-bats in some capacity this season and he could impress enough in March to win the second base job.
Luis Castillo, meanwhile, has to "earn" a spot on the roster according to Mets GM Sandy Alderson. He's battled foot and knee injuries lately and is nothing more than a slap hitter with an average glove.
If it's Castillo, expect a lot of singles and some costly errors. If it's Murphy, expect a pure hitter with some pop. Other candidates are Ruben Tejada, Luis Hernandez, Justin Turner, and Brad Emaus.
