Nationals catcher Wilson Ramos has a broken bone in his left hand and surgery to repair it will cost the 26-year-old four to five weeks, manager Matt Williams confirmed on Wednesday during an interview on 106.7 The Fan in Washington.

Ramos suffered the injured in Monday's season-opening win over the Mets. He broke the hamate bone in his left hand during the top of the seventh inning on a foul tip, according to Williams.

The Venezuela native hit .272 with 16 home runs and 59 RBIs in 78 games last season. He missed 59 games with a hamstring injury and also missed most of the 2012 season with a right knee injury.

In parts of five seasons, Ramos is a .269 hitter with 35 homers, 125 RBIs and a .767 OPS.

Jose Lobaton will take over as Washington's primary catcher with Ramos out, and Sandy Leon will be called up from minor league camp to be the backup.
