WASHINGTON (AP) - Bryce Harper tied a career high with four hits and reached base in all six plate appearances as the Washington Nationals routed the St. Louis Cardinals 14-6 on Monday night.
Harper drove in three runs during his first four-hit game since April 17, 2013.
Stephen Drew, Adam Eaton and Ryan Zimmerman each had three of Washington's 19 hits, and the Nationals overcame four errors by breaking open the game in a seven-run eighth inning.
Tanner Roark (2-0) allowed five runs — three earned — over five innings. The right-hander worked around three errors committed behind him.
Cardinals starter Adam Wainwright (0-2) gave up six runs and 11 hits over four-plus innings.
Stephen Piscotty returned to St. Louis' lineup after missing two games with a sore left knee and knocked in two runs.
Wainwright failed to retire any of the three batters he faced during the Nationals' three-run fifth, and exited after his 96th pitch, a 1-0 fastball that Drew belted to deep right for an RBI double that pulled Washington to 5-4.
Matt Wieters followed with a tying single off Brett Cecil. Two batters later, Eaton delivered a go-ahead sacrifice fly.
Washington added seven more runs in the eighth. The last two came on Harper's two-out single that scorched past second baseman Kolten Wong and was not ruled an error because of a bad hop.
Harper slid into first base on his third hit, his belt coming loose as his body slammed against the infield clay on a bunt single in the sixth inning. In the seventh, the right fielder doubled off Matt Carpenter at first base on Piscotty's lineout.
Cardinals: RHP Trevor Rosenthal (right lat strain) returned from the disabled list to strike out the side in the seventh. St. Louis manager Mike Matheny said he hopes to ease Rosenthal, the team's closer for most of 2014-16, into higher-leverage situations. "He's not going to scare," Matheny said. "He's going to handle any situation. The game will dictate what that opportunity will look like."
Nationals: Manager Dusty Baker said the decision to place SS Trea Turner (right hamstring strain) on the disabled list was made easier because of MLB's new 10-day DL. "I think baseball did one of the best things they've done in a long time," Baker said of the rule change in the latest collective bargaining agreement, which cut the minimum DL stay from 15 days to 10 for non-concussion-related injuries.
Cardinals: RHP Lance Lynn looks to build upon 5 1/3 innings last week in his first start since 2015 after missing last season recovering from elbow surgery.
Nationals: Gio Gonzalez will try to improve his numbers against Cardinals leadoff man Dexter Fowler, who is 10 for 20 with a homer and four extra-base hits against the lefty in his career.
