Team home runs in consecutive games.

Joe DiMaggio got at least one hit in 56 consecutive games in 1941: May 15 through July 16. That's the legendary DiMaggio streak, which is still the record.

Much less well known was that DiMaggio and his 1941 Yankee teammates hit at least one home run in 25 consecutive games from the second game of a doubleheader June 1, 1941 through June 29, 1941. That team streak was obviously embedded within the individual DiMaggio streak. Perhaps this had an impact:

Since 1994 that team record of 25 has been equalled by four teams, including three National League teams, which like the 1941 Yankees, had the pitcher bat. It has also been surpassed by two teams:
2002 Texas Rangers 27
2019 Yankees 29 and counting.

The 2019 Yankees are off to London to play two regular season games against the Boston Red Sox. The team home run streak will be on the line in London. Link to generate table:

Of the eight teams listed above, only Texas, Detroit and the 2019 Yankees had the advantage of the designated hitter (DH) batting instead of the pitcher.

Of the seven teams with streaks of at least 25 games, the 1941 Yankees hit the fewest home runs during their streak: 40. The 2019 Yankees have hit 53 home runs during their 29 game streak. Texas hit 55 home runs in its 27 game streak. Texas also had the most at bats: 950. The 1941 Yankees had the second fewest: 856.
