ARLINGTON, Texas (Reuters) - Texas Rangers outfielder Josh Hamilton is still hospitalized with a case of pneumonia but has shown significant improvement and is expected to be released this weekend, the team said on Wednesday.

The reigning American League Most Valuable Player was diagnosed with an early case of pneumonia on Monday and was still being treated in order to accelerate his recovery, the Rangers said in a statement.

According to the Rangers, Hamilton should be able to resume his conditioning and baseball activities within a few days after his release from the Texas hospital.

Hamilton hit .359 with 32 home runs and 100 RBIs last year for the Rangers, who advanced to the World Series for the first time in the 50th year of the franchise but lost to the San Francisco Giants in five games.
