WASHINGTON (AP) Lane Thomas homered to highlight a seven-run third inning, and the Washington Nationals routed the Miami Marlins 8-1 on Friday night in the opener of a three-game series. MacKenzie Gore struck out 10 over seven innings for Washington, which has won six of seven and improved to 5-0 against Miami this season. The Marlins, who are an NL-worst 23-46, have lost three in a row and nine of their last 11. Miami fell to 3-21 when facing a left-handed starter. Gore (6-5) won for Koda Glover Jersey the fourth time in five starts, giving up a run on five hits while matching the longest outing of his career. Gores good, Miami manager Skip Schumaker said. I had him in San Diego as a young kid and seeing him mature into what he is today is great to see, when were not playing him. He was on the attack. The Nationals chased Miami starter Shaun Anderson (0-1), who was called up from Triple-A Jacksonville earlier in the day, with seven consecutive hits many early in the count to start the third. After Jacob Youngs leadoff single, CJ Abrams had a sharp infield single on the next pitch and Thomas followed with a . Je se Winker turned Andersons first offering into an infield single, and Eddie Rosario sent an 0-2 fastball to right for a double. Joey Meneses poked a first-pitch single to left to score two runs, and Luis Garca Jr. ended Andersons night with a hit on a 1-0 fastball. You dont want to fall behind, Washington manager Dave Martinez said. Its hard enough to hit. To hit with two strikes is tough. Be aggre sive and be aggre sive with balls in the strike zone, and we really did that today. Four batters later, to left to make it 7-1. The seven runs all charged to Anderson matched the most scored by the Nationals in one inning this season. Washington also did it in the fourth inning of Sundays 8-5 victory over Atlanta. Anderson, who was purchased from Texas on May 30 and was making his Marlins debut, gave up hits to 10 of the 15 batters he faced. It was his first major league start since Aug. 7, 2019. He just kind of got in the middle of the plate a little bit, Schumaker said. The stuff is OK. He just needs to play a little bit more on the edges, and the height of the pitches I think was just exactly where they probably wanted them and a little bit higher than probably he wanted them. Catcher Nick Fortes drove in Miamis run with a two-out single to third baseman Nick Senzel in the second. In the dugout in the middle of the second, Gore and Senzel , and both players downplayed it after the game. Weve handled it in here, Gore said. I think the biggest thing is that that was something I cant do. But Im going to leave it at that. Thats on me.
