MLB Heat Check, Boston Red Sox 8-2 in Their Last 10

Every MLB season has a week when the temperature map redraws itself, and this feels like one of them. Boston Red Sox have become the team nobody wants to see next on the schedule, while Oakland Athletics are hunting for anything that resembles a good night.

The warm end of the table

Start with Boston Red Sox. They have won 8 of their last 10, and they have not been sneaking past anyone: the runs margin over that stretch is +35, which breaks down to about 7.4 scored and 3.9 allowed per game. That is the arithmetic of a team winning on merit, not on bounces.

The chase belongs to Atlanta Braves, who have gone 8-2 with a +24 margin of their own.

And do not sleep on Tampa Bay Rays, quietly 8-2 across their last 10.

For scale, the league as a whole is averaging 4.3 runs a game over this window, Boston Red Sox are clearing that bar by 3.1 a night all on their own.

The deep freeze

Then there is Oakland Athletics. A 1-9 stretch is ugly on its own; pair it with a -42 runs margin and it stops looking like bad luck. They are being outscored by about 4.2 runs a game, and no scheduling quirk explains that away.

They have company at the cold end: Los Angeles Dodgers, 2-8 over the same window.

The middle of the table is where the real congestion lives: St. Louis Cardinals (5-5) and Chicago White Sox (5-5) are separated by almost nothing, and one good weekend reshuffles the whole neighborhood.

The board

The top of the ledger, at a glance:

The fine print

One reading tip before you go: runs margin travels better than record. A fat margin with a modest record usually means the wins are coming; the reverse usually means they are not.

Next up on the slate: Boston Red Sox against Toronto Blue Jays. Check back after that one goes final.
