The Padres continued to get on base, but they couldn’t turn those runners into runs.
And near the end of a futile and frustrating day, one of their new relievers faltered. Then their most reliable reliever did, too.
The Diamondbacks scored two runs off Padres closer Kirby Yates to break a ninth-inning tie and hand the Padres their first loss in three games this season, 4-3 Sunday at Petco Park.
The home team’s chance to be 3-0 for the first time since 1984 and also the major leagues’ only undefeated team this season crumbled when the Diamondbacks scored two runs off Emilio Pagán in the eighth inning and the pair off Yates.
