It was a game of sloppy pitching and missed opportunities, thus the Astros handed the Mariners a rare win at Minute Maid Park in the first game of a three-game series.
The Mariners opened the scoring against Astros starter Cristian Javier with a J.P. Crawford double that scored Julio Rodgriguez.
But Jose Altuve answered in the bottom of the inning with yet another leadoff homer to tie the score, this time off Robbie Ray.
Cal Raleigh gave the Mariners a 4-1 lead with a homer but in the bottom of the inning, Kyle Tucker cut the lead in half with a solo shot of his own, his 11th and second in two games.
