(AP) — Bryce Harper had never hit a grand slam until he smashed his 100th career home run last week. He now has two grand slams since Thursday after launching another during a seven-run, four-homer seventh inning that highlighted the Washington Nationals' 7-0 win at Miami.

Marlins starter Adam Conley was working on a four-hit shutout until Jayson Werth and Wilson Ramos hit back-to-back solo homers with one out in the seventh. Harper's slam came off reliever Chris Narveson, who also served up Ryan Zimmerman's solo blast.

Stephen Strasburg allowed just three hits while striking out 10 in eight innings to help the Nats end a two-game skid and improve to 10-3.

Elsewhere in the majors:

  • Kansas City outscored Detroit 8-6 as Salvador Perez hit a three-run homer and had a career-high five RBIs. Perez hit a two-out, two-run double in the third before his two-out shot in the fifth gave Kansas City an 8-2 lead.
  • Oakland pulled out a 3-2 win over the New York Yankees on Mank Canha's RBI single in the 11th inning. Jed Lowrie provided a run-scoring single that tied the game 2-2 in the sixth.
  • Boston and Tampa Bay were scoreless until Kevin Kiermaier belted a solo homer leading off the 10th inning of the Rays' 3-0 shutout of the Red Sox. Desmond Jennings added a two-run double and Rays starter Drew Smyly struck out 11 while combining with two relievers on a one-hitter.
  • Jason Hammel combined with three relievers on a six-hitter and supplied a two-run single to lead the Chicago Cubs past St. Louis 2-1. Hammel and the Cubs' bullpen blanked the Cardinals following Yadier Molina's RBI triple in the second.
  • Logan Verrett tossed six shutout innings and Neil Walker smacked two of the New York Mets' six home runs in an 11-1 laugher against the Phillies in Philadelphia. Yoenis Cespedes hit a three-run shot for the Mets, who also got homers from Michael Conforto, Lucas Duda and Curtis Granderson.
  • Troy Tulowitzki lined a two-run double while Toronto was building a 4-1 lead in a 4-3 victory at Baltimore. Marcus Stroman served up homers by Manny Machado and Matt Wieters but just four other hits in seven innings to move to 3-0.

  • Billy Hamilton poked a two-run double while Cincinnati was scoring four times and stealing five bases in the second inning of a 4-3 verdict over Colorado. The Reds got great pitching from rookie Robert Stephenson, who held the Rockies to a run and three hits in seven innings.

  • The Braves have won four straight since an 0-9 start after Tyler Flowers was 4-for-4 with three RBIs to carry Atlanta's 8-1 romp over the Dodgers. Jeff Francoeur had two hits and scored twice to back reliever Ryan Weber, who gave up a run and three hits with four K's in 3 2/3 innings.
  • Robbie Ray pitched well in Arizona's 3-0 shutout of San Francisco, holding the Giants to five hits and fanning eight in six innings. The game was scoreless in the fifth until Jean Segura hit an RBI single and scored on Jake Lamb's run-scoring triple.
  • San Diego trailed 3-0 until Wil Myers, Derek Norris and Adam Rosales homered in the Padres' 5-4 comeback over Pittsburgh. Myers began the rally with a two-run blast in the fourth, one inning before Norris hit a two-run shot to put the Padres ahead to stay.
