HOUSTON — A healthy Carlos Correa is a dangerous Carlos Correa.

Correa extended the longest hitting streak of his career to 16 games by going 3-for-4 in Monday’s 6-4 win over the Royals, including a long homer in the second inning off Royals starter Jakob Junis. The Astros have won three in a row.

Hampered in the second half of last season by back problems, Correa crushed a 2-2 slider from Junis, and sent it 424 feet over the left-center field wall at Minute Maid Park to give the Astros a 2-0 lead in the second inning. Correa’s hitting streak is the longest active streak in the big leagues and the longest of his career.

Correa’s previous longest homer of the season was 396 feet off the Twins’ Ryne Harper on April 22. It’s Correa’s longest homer since hitting a 455-foot bomb last June 15, which also came off Junis in Kansas City.

George Springer led off the game with a solo homer off Junis, giving him 27 leadoff homers in his career. He’s reached base safely in 32 of his 33 starts. Robinson Chirinos hit a two-run homer in the sixth off Junis to put the Astros ahead, 5-4.
