T.R. Sullivan reports that Texas Rangers reliever Joakim Soria has been diagnosed with a strained chest muscle.

Sullivan says that Soria was on track to be back in the majors before June 1, but now, because of this injury, he won't throw for 2-3 weeks, and is not expected back until July 1 at the earliest.

Soria, who is recuperating from Tommy John surgery, signed a 2 year, $8 million deal with the Rangers this past offseason that includes a $7 million team option for the 2015 season.

Soria, a Rule 5 selection of the Kansas City Royals from the San Diego Padres prior to the 2007 season, was one of the best relievers in baseball from 2007-10. Soria had a disappointing 2011 season, however, and then underwent Tommy John surgery in April, 2012.
