According to Elias

Trevor Plouffe (twice), Josh Willingham and Drew Butera all homered in the Twins’ 10-8 victory over the Royals at Minnesota. It was the first time that the Twins have hit more than three home runs in a game at Target Field, which opened for business in 2010. Minnesota entered Sunday’s game with a streak of 204 consecutive home games without hitting as many as four homers in a game (since October 4, 2009, at the Metrodome). The longest current streaks of that kind belong to the Pirates (234 home games) and Athletics (218). Source: Elias
