SAN DIEGO — Wil Myers hit a game-ending three-run homer with two outs in the seven-run seventh inning for the San Diego Padres, who got two homers and four RBIs from Manny Machado in beating the Seattle Mariners 10-7 Thursday in the first game of a doubleheader.

Game two ended after press deadline.

The first game was a makeup of Wednesday night’s game, which was postponed after the Mariners voted unanimously not to play as a protest of the shooting of Jacob Blake in Kenosha, Wis.

The Mariners have the most Black players in baseball, eight on the active roster and 11 on the 40-man roster.

San Diego rallied from a 7-3 deficit to stun the Mariners, scoring all the runs with two outs. After Craig Stammen allowed four runs in the top of the seventh, Seattle’s Taylor Williams (0-1) gave it right back in the bottom of the inning. He gave up a two-run, bases-loaded single to Machado. Another run scored on a wild pitch, and Eric Hosmer tied it with an RBI single.

Dan Altavilla came on and allowed rookie Jake Cronenworth’s single before Myers homered to left, his eighth of the season.

Pierce Johnson (3-1) got the win.

The Padres had tied the game 3-3 with impressive home runs by Fernando Tatis Jr. and Machado to open the sixth inning. Tatis hit his big league-leading 13th homer an estimated at 448 feet onto the roof of the Western Metal Supply Co. Building in the left-field corner at Petco Park, making him just the second Padres player to homer to the top of the landmark.

Machado followed with a shot into the second deck in left field, his second of the game and ninth this season. Both were off Matt Magill.

Stammen allowed all five batters he faced to reach, including Sam Haggerty, Kyle Lewis and Kyle Seager with RBI base hits. Seager’s hit chased Stammen, and Austin Nola hit a sacrifice fly off Johnson.

Until San Diego’s impressive home runs, the Padres were trailing a Mariners team getting big contributions from two rookies pressed into duty without much notice.

Ljay Newsome pitched four strong innings in his first big league start after Taijuan Walker was traded for a player to be named later earlier in the day, and fellow rookie José Marmolejos hit a two-run homer after being added as the “29th man” for the doubleheader.

Newsome, 23, made the emergency start about three hours after the Mariners announced they sent Walker to the Toronto Blue Jays.

Newsome, making his second big league appearance, retired the first seven Padres batters and 10 of 11 before Machado homered to left-center with one out in the fourth, his ninth. Newsome allowed three hits, struck out four and walked none.
