The Washington Nationals acquired left-hander Marc Rzepczynski and cash from the Oakland Athletics for Max Schrock on Thursday.
A free agent at the end of the season, Rzepczynski posted a 3.00 ERA in 56 relief appearances for the A's in 2016. The 30-year-old struck out 37 batters in 36 innings and is holding right-handers to a .226 batting average this season; left-handers have an average of .296.
