The Nationals returned from rehab and reinstated second baseman Daniel Murphy from the 10-day disabled list and optioned infielder Adrian Sanchez to Triple-A Syracuse on Tuesday.
Murphy, 33, joins the Nationals after missing the first 64 games of the season rehabilitating from offseason right knee surgery. He went 9-for-37 (.243) with two doubles, two homers, seven RBIs, six walks and eight runs scored in 10 rehab games with Double-A Harrisburg.
Murphy is coming off a 2017 season in which he hit .322 with 43 doubles, three triples, 23 home runs, 93 RBI, 52 walks and 94 runs scored in 144 games.
