Platoon at 1B new LF...

According to Adam Rubin his sources believe that the Mets will look to fill the power void with a left fielder through free agency while trading for a right handed 1B to platoon with Murphy.

This appears to be a result of the market along with the emergence of Ike Davis. The market has several quality left fielders, lead by Matt Holliday and Jason Bay, who if your willing to pay would be a great addition to any team.

In addition to not wanting to block Davis for the 2011 season the 1B market is thin and the rumored 1B available for trade will cost a lot ( Fielder / Gonzalez).

However, right handed first baseman aren't easy to find;

Ryan Garko maybe a non-tender candidate, the Giants are said to be interested in Nick Johnson and after coming over in a trade, Garko struggled at the plate. The 28 y/o right hander who has been a platoon player most of his career would top my list, he's a lifetime .280 hitter and was hitting .285 in Cleveland, after the trade in limited action he hit .235.

Connor Jackson maybe available if your willing to risk that he recovers from Valley Fever and Kevin Kouzmanoff maybe a solid pickup but only has 6 minor league games at the position. A low budget stop gap free agent would be Xavier Nady, otherwise there isn't much out there.

It's still risky to go into the season with Murphy at first even in a more limited role, I would prefer a better firstbase option such as LaRoche...

While the Mets know they need to get an upgrade in power in left field or first base, I get the sense it will be in the outfield. There's little sense blocking prospect Ike Davis by signing a first baseman to a multi-year deal. I'm told the Mets likely will trade for a righty-hitting first baseman with a short-term commitment to pair with Daniel Murphy in 2010. source Daily News
