According to ELIAS

What’s better than triple-double? How about a triple-triple.

Eduardo Nunez, Shane Robinson, and Eduardo Escobar all tripled in the sixth inning for the Twins yesterday. And if that doesn’t seem unusual enough for you consider this: Minnesota scored only one run in the inning, with Robinson getting picked off and Escobar getting stranded. The Twins did win the game 4-3.

It was the first time since the Washington Senators moved to Minnesota in 1961 that the Twins had three triples in one inning. And it was the first instance in the expansion era of a team scoring only once despite three triples in an inning. The other 20 teams to do so averaged 4.6 runs in those innings. Source:ELIAS
