Nationals' Ryne Harper: Rejoins big-league squad

Harper was recalled from Triple-A Rochester on Tuesday, Dan Kolko of MASN Sports reports.

The righty has pitched in six games between two stints with the Nationals this season, posting a 1.13 ERA with five strikeouts in eight innings of relief. Harper will help fill the void left by Tanner Rainey (leg), who landed on the 10-day injured list Tuesday.
