The Red Sox have hit 3+ HR in at least 15 different games in every season since 2001, the longest active streak in the majors:

BOS 13
TOR  5
BAL  3
TEX  3

They are in sight of the longest such streak since 1950:

NYY 15 (1998-2012)
TEX 14 (1996-2009)
BOS 13 (2001-    )
CHC 11 (1998-2008)

What’s more, 2000 is the only season in which Boston did not accomplish that feat since 1995 (they had only 13 such games that year), so they’ve done it in 18-of-19 seasons.

Problem is, they’ve had exactly TWO such games this year. Only two clubs, the Twins (1) and Royals (1) have fewer. The Sox went from May 4 through June 21 without clubbing three or more homers in any game. That 44-game streak is their longest since a 55-gamer back in 2000 (July 7 through Sept 6).

Longest MLB streaks without hitting 3+ HR in a game since 2000:

128 – Cardinals (8/22/13 –    )
116 – Marlins (6/25/13 – 5/2/14)
103 – Royals (5/9/13 – 9/3/13)

Note this: St. Louis holds the record for the longest such streak since 1950, at 282 games, from 4/22/88 through 9/1/1989.
