The New Hampshire Fisher Cats made history Tuesday night in Portland, Maine, by scoring 8 runs without a hit in a single inning—a feat unseen by a major‑league club in the expansion era. The run surge came after a series of eight walks, two hit‑by‑pitch, four wild pitches, a sacrifice fly and a lone single by Ismael Munguia.

Portland starter Hayden Mullins opened with a strikeout, but his control slipped, issuing a walk, a wild pitch and a second walk before the score tied at 2‑2. Reliever Jorge Juan compounded the collapse, striking out a batter with bases loaded and then walking three more, allowing four runs on wild pitches and a hit‑by‑pitch.

The Fisher Cats capped the inning and the game, winning 12‑7 victory in cold, 35‑degree weather. No major‑league team has ever scored more than four runs without a hit in an inning, and only 16 times in MLB history has a pitcher allowed five runs without a hit in 1 ⅔ or fewer innings. The performance underscores the volatility of relief work in the minors.
