The Width of One Run

Atlanta has won seven consecutive baseball games. The margins, in order, read 2, 1, 1, 1, 2, 1, 1.

That is the whole story, and it is also the reason the story is difficult to tell honestly. Five of the seven wins came by exactly one run. A one-run game is the least informative outcome in baseball — the sample where luck does most of its work, where good teams and mediocre teams separate by almost nothing. Five of them inside eight days is either evidence of a roster that has learned how to win the close ones, or evidence of a roster that was handed seven coin flips and called them all correctly. The numbers tell a story, but not the one you would expect. Mostly they tell you how little room there has been.

Sunday afternoon was the compressed version of the whole week. Tyler Mahle went 6.2 innings against Colorado, allowed five hits and one run, walked nobody, and struck out nine on 89 pitches. Sean Murphy hit a solo home run. That was the entire offensive plan for six innings, and it was working. Then Dylan Lee gave the run back in the eighth — two hits, one earned — and the game went to extra innings tied at two, which is where these things go now.

Victor Mederos threw a perfect tenth. Matt Olson singled to right, Brewer Hicklen scored, and 31,776 people at Truist Park went home having watched Atlanta win a baseball game by one run for the fifth time in eight days.

By the numbers

Here is what makes the stretch genuinely interesting rather than merely pleasant: the offense is not doing this.

The lineup that produced seven straight wins is hitting, by season average, as follows. Michael Harris II .295. Drake Baldwin .277. Mauricio Dubón .270. Olson .258. Ozzie Albies .254. Ronald Acuña Jr. .241. Mike Yastrzemski .225. Austin Riley .220. Murphy .218. Ha-Seong Kim .081. Riley and Murphy are both hitting under .225 for the season. This is not a group that bludgeons anyone, and it has not been asked to. The runs have been scarce because the runs were always going to be scarce.

So the pitching has held instead. Mahle in particular has been the load-bearing wall. Across six August starts he has thrown 36 innings and allowed ten earned runs, a 2.50 ERA for the month. You can watch it register in his season line, which has come down after every single August outing: 5.13, then 4.83, then 4.64, then 4.53, then 4.41, and now 4.25. A season ERA is a slow-moving object by design. Pulling it down nearly nine-tenths of a run inside four weeks means the recent work has been considerably better than the cumulative number still admits.

Which raises the thing worth carrying over from yesterday. The arms holding this streak up are not the ones the organization spent a decade growing. Hurston Waldrep and Spencer Schwellenbach are recovering from surgery. The rotation keeping a first-place team in first place is, substantially, acquired. That is either a front office reading its own roster correctly, or a bill that has not come due yet. Baseball has a long memory, and it has a habit of sending the invoice in October.

One more piece of accounting, because it has been reported the other way around. Acuña was benched during the Dodgers series on August 27. Since then, and across the streak generally, he is 8-for-21 with six walks — a .381 average over the stretch — and his season line has climbed from .228 to .241 in five games. Whatever was said in that dugout, the response has been the most productive week he has had in months. That is not a slump. That is a correction, and it arrived at a useful moment.

The Braves are 82-55, first in the National League East by five games over Philadelphia, and carrying the same record as the Dodgers. The Giants, 56-81, are at Truist Park tonight.

There is a version of this season where seven one-run wins in late August means Atlanta has built a roster that survives close games, and there is a version where it means Atlanta got lucky in a week that did not ask very much. The difference between those two versions does not get settled tonight. It gets settled September 4 through 6, in Philadelphia, against the only club in this division still counting.
