Two Grand Slams Power Cubs to Historic 19-2 Rout of Mariners

The Chicago Cubs put on an offensive clinic Sunday afternoon in Seattle, demolishing the Mariners 19-2 behind a rare dual grand slam performance that etched another chapter into franchise history.

Ian Happ and Pedro Ramírez each crushed grand slams and drove in five runs apiece, while Pete Crow-Armstrong added a solo home run in a game that saw the Cubs score their highest run total of the season. The victory improved Chicago to 75-56 on the year and helped them avoid a three-game sweep in the Pacific Northwest.

Happ opened the floodgates in the third inning with a 378-foot blast that gave the Cubs a 5-3 lead. The left fielder's 22nd home run of the season came with the bases loaded and set the tone for what would become a historically lopsided affair.

Ramírez followed suit later in the game with his own grand slam, matching Happ's five-RBI output and creating a moment of Cubs history. The duo became just the fourth pair of Cubs teammates to hit grand slams in the same game, joining an exclusive club that spans over a century of franchise baseball.

The Mariners, who fell to 65-68 with the loss, had no answers for Chicago's relentless attack. Seattle's pitching staff surrendered hit after hit as the Cubs piled up runs across multiple innings, turning what started as a competitive game into a blowout by the middle frames.

For Chicago, the victory provided a crucial momentum boost as they continue their push toward the postseason. Currently sitting in strong position for a playoff berth, the Cubs have relied on balanced offensive production throughout the season, but Sunday's outburst demonstrated the team's ceiling when multiple hitters get hot simultaneously.

Happ, who has been a cornerstone of the Cubs' lineup, extended his solid season with the grand slam performance. His ability to deliver in high-leverage situations has been a recurring theme in Chicago's success this year, and the fifth-inning heroics reinforced his value to the team.

Ramírez's grand slam added insurance runs that turned the game into a laugher, allowing manager Craig Counsell to rest key players in the late innings while building confidence heading into the final month of the regular season.

The 19-2 final score marked the largest margin of victory for the Cubs in over two months and sent a clear message to the rest of the National League: when Chicago's offense clicks, they can overwhelm any opponent.

As the Cubs return home for their next series, they'll carry the confidence of a historic offensive performance that reminded the baseball world of their potential when the bats come alive at the right time.
