Robles' 10th-inning single lifts Mariners past Diamondbacks in sweep

On a Sunday night in Seattle, a mishandled grounder in the tenth inning became the quiet punctuation mark on something larger — a six-game winning streak, a third series sweep, and the emerging portrait of a team discovering its own depth. The Mariners did not merely beat the Diamondbacks; they absorbed their resilience, answered their comebacks, and ultimately outlasted them in the extra frame where seasons begin to take shape. In the long arc of a baseball year, such weekends are less about scores than about identity — and Seattle, it seems, is finding theirs.
