The Red Sox have struggled as a team over the past few weeks thanks to either the offense disappearing or the pitching staff imploding. They have gone 4-6 in their last 10 games after looking strong and maintaining an AL East lead for a lot of the early season. Given this stretch, one might assume the Red Sox have fallen back in the division and need to play catch-up, but thanks to wide-spread mediocrity, that assumption is wrong.
The rest of the AL East has also been struggling right along side the Red Sox, so they only sit 1 game back of the Baltimore Orioles as of June 22. The surging Toronto Blue Jays have cooled off a little and are 6-4 in their last 10 games, while the Orioles (4-6), Yankees (4-6), and Rays (3-7) all have below .500 records over that same span. As of writing this, all 5 divisional teams have lost at least 2 straight games and the lowly last place Tampa Bay Rays are riding a 6-game losing streak.
All this is to say the AL East is a wide-open division. All 5 teams have major flaws and have been wildly inconsistent. The division will likely come down to who can stabilize most effectively down the stretch; perhaps with the addition of a player or two at the trade deadline.
