The Milwaukee Brewers edged the Oakland Athletics 15-14 in 12 innings on June 2, 2026, in a game defined less by the final score than by Kyle Harrison’s worst start of the season — he allowed eight earned runs in 2 1/3 innings while the contest produced 11 home runs.
Harrison, who was traded to the Brewers in the offseason after leaving the Boston Red Sox organization, entered the day with a 1.57 ERA and just 10 runs allowed on the season; on Monday he struck out four batters but surrendered three home runs and eight earned runs before leaving after 2 1/3 innings.
The numbers drove the result: a slugfest at Las Vegas Ballpark — the Triple-A home of the Las Vegas Aviators — that served as the first major-league game played in Las Vegas since 1996 and one of the rare modern MLB affairs staged outside a club’s regular park. The Athletics are using the Aviators’ facility for a six-game homestand as they prepare to move into a new Las Vegas ballpark in 2028.
The most jarring detail is the contrast between Harrison’s season before Monday and his outing in Las Vegas. He had been among the game’s early-season success stories with a 1.57 ERA and only 10 runs allowed; he left Monday night having given up eight earned runs and three homers. Harrison said he "did not want to use the ballpark as an excuse," a concession that highlights the gap between the performance the Brewers expected and the one they received.
The game itself turned into a pitcher’s nightmare and a hitter’s carnival — 11 home runs in total — and it exposed how quickly a single start can undo months of work for a starter. Yet the Brewers still won, which frames the outing differently for club and fan: the bullpen and offense bled into a long night that ended with a narrow win, but Harrison’s line will be a focal point for analysis and for his upcoming rotation turns.
What remains unresolved is how much the makeshift venue contributed to the barrage of homers and to Harrison’s slide. The Athletics are in the midst of their temporary Las Vegas homestand and will play at the Ballpark for five more games; the decided long-term change is already scheduled — Oakland will move into a new Las Vegas stadium in 2028. For Harrison, the next turn in the rotation will be watched closely as the pitching staff looks to re-establish the consistency he showed before Monday.
For readers searching under names like Caleb Durbin, this game will register in box scores and highlights as an outlier: a historic location, an 11-homer shootout and a starter with a 1.57 ERA posting his season-worst line while his team eked out a 15-14 victory in 12 innings.
