DJ Herz was masterful in his third career start, striking out 13 and allowing one hit over six stellar innings to lead the Washington Nationals to a 4-0 win over the Miami Marlins on Saturday.

Herz, a 23-year-old left-hander who made his major league debut on June 4, struck out eight of the first 10 batters and his total was the second-highest by a rookie for the Nationals since the team moved to Washington for 2005, surpassed only by Stephen Strasburg’s 14 in his debut on June 8, 2010.

Herz did not make it out of the fifth inning in his first two starts but didn’t allow a runner in this one until Jake Burger’s leadoff single in the fifth. He struck out the side in the third and sixth innings and was lifted after throwing 84 pitches.

He joins Strasburg as the only pitchers in major league history to strike out at least 13 without a walk in one of their first three career outings.

Herz also is just the third pitcher since 1988 to fan at least 13 on fewer than 85 pitches. The others are Clayton Kerhsaw (2022) and Greg Maddux (2000).

Dylan Floro, Hunter Harvey and Kyle Finnegan finished the four-hitter to seal Washington’s seventh win in eight games.

The Marlins lost their fourth straight and dropped to 2-10 in June.

Yamamoto leaves early in Dodgers’ loss

Seth Lugo became the second 10-game winner in the majors and MJ Melendez hit a grand slam after Yoshinobu Yamamoto exited early in the Kansas City Royals’ 7-2 victory over the Los Angeles Dodgers.

Yamamoto left after two innings due to triceps tendinitis following two scoreless innings. This is Yamamoto’s first year in the majors after he signed a record $325 million, 12-year contract in December.

He had thrown over 100 pitches in four consecutive starts entering Saturday and his scheduled start on Thursday against Texas was pushed back for extra rest.

Lugo limited the Dodgers to two runs and six hits in six innings to join Philadelphia’s Ranger Suarez as the only 10-game winners in the majors.

The Royals got all the offence they needed in the sixth to erase a 2-1 deficit. Vinnie Pasquantino, Nelson Velazquez and Freddy Fermin all drew one-out walks off Blake Treinen, who struck out pinch-hitter Adam Frazier before Melendez connected on the 12th pitch of his at-bat for his first career grand slam.

Santander powers Orioles past Phillies

Anthony Santander hit a pair of home runs and drove in four to back Grayson Rodriguez’s strong start as the Baltimore Orioles defeated the Philadelphia Phillies, 6-2 in a matchup of two of baseball’s top teams.

Santander hit a tying solo homer in the fourth inning and his two-run blast in the eighth extended the lead to 5-2. He also added a sixth-inning sacrifice fly.

Santander leads the majors with eight home runs in June.

Rodriguez allowed two runs on seven hits over seven innings with one walk and six strikeouts to win his third straight start.

Edmundo Sosa hit a solo homer for the NL-best Phillies, who have lost three of four.
