Robbie Ray overcame five walks to hold the Seattle Mariners to just one run over six innings, Jung Hoo Lee and Matt Chapman combined for four doubles and four runs, and the San Francisco Giants won their sixth in a row Saturday night with a 4-1 home win.

Pitching against the team that signed him to a five-year, $115 million free-agent deal in December 2021, Ray (2-0) surrendered a solo home run to Dylan Moore in the fifth. Ray, though, held Seattle to just three other hits — all singles — in one of his best outings since joining the Giants in a trade last season.

Ray left with a 4-1 lead, having struck out two, after just his third six-inning outing since he was a 12-game winner for Seattle in 2022.

Lee and Chapman did the heavy lifting for the San Francisco offense, lacing back-to-back doubles in both the fourth and sixth innings.

The first set of two-baggers produced the Giants’ first run in the fourth, after which Mike Yastrzemski singled home Chapman for a 2-0 lead.

After Moore’s second homer of the season cut the Seattle deficit in half, Lee and Chapman doubled up on doubles again for a 3-1 lead in the sixth. This time, it was Wilmer Flores who singled home Chapman to complete a two-run inning.

Mariners starter Bryce Miller (0-2) was pulled with one out in the sixth inning and was charged with all four San Francisco runs on seven hits. He walked three and struck out four.

Hayden Birdsong followed Ray with two scoreless innings, striking out two, before Ryan Walker worked a one-hit ninth for his third save of the season.

The Giants haven’t lost since 3-2 at Cincinnati in the second game of the year.

The doubles by Lee, who added a seventh-inning single to cap a three-hit night, and Chapman were the only extra-base blows for the Giants, who outhit the visitors 10-7. Flores chipped in with a pair of singles.

Moore added a single for a two-hit night and Victor Robles had two singles for the Mariners, who have dropped four of five.
