Murphy (hamstring) is in the lineup for Monday's game against the Nationals, Anthony DiComo of MLB.com reports. A hamstring injury threatened to keep Murphy out for the start of the year, but he was able to recover in short order and will get the start at second base for the Mets on Opening Day. Murphy will also bat fifth in the order, a spot in which he logged just three at-bats last year. David Wright will bat second.
