For people who don't watch baseball

Baseball, Explained Nightly

Everything happening in the sport right now, explained from scratch — and then last night's games. Read it in five minutes and hold your own in the conversation.

If you only remember three things

  1. Who is actually winning
  2. The fastest arm in baseball: Jacob Misiorowski
  3. Pete Crow-Armstrong is about to join a club nobody joins

What's been happening this season

The standing stories. Read these first — last night's scores don't mean much without them.

Who is actually winning

Six divisions, and the winner of each goes to the playoffs. Of the 30 clubs, the Brewers have won the most: 103-59. The two tightest races right now: AL Central: Guardians (85-77) lead the White Sox by 1; AL West: Astros (81-81) lead the Rangers by 1.

Say this “The Brewers have more wins than any of the other 29 clubs and it’s barely being discussed.”

The fastest arm in baseball: Jacob Misiorowski

Jacob Misiorowski throws a baseball harder than anyone else alive. Of the 25 fastest pitches thrown in the major leagues this season, 19 are his. He topped out at 105.5 mph, and the fastest pitch by anybody else all year was 104.5. He has reached that shelf in 8 different games. There is one nuance worth having: Mason Miller averages more (101.4 mph) — but he is a RELIEVER, throwing 555 pitches all season, one inning at a time. Misiorowski is a starter who averages 100.6 mph across 1677 pitches. Holding that for six innings is the harder thing by a distance. And he is not merely wild: 252 strikeouts against only 44 walks, with a 1.80 ERA against a league average near 4.00.

Say this “The thing about Misiorowski isn’t the 105.5 — it’s that he’s a starter holding 100.6 average over 1677 pitches. Relievers do that for one inning.”

Pete Crow-Armstrong is about to join a club nobody joins

Thirty home runs and thirty stolen bases in the same season is called 30/30. It is rare for a simple reason: the players with enough power to hit thirty are usually too big to steal thirty, and the players fast enough to steal thirty usually cannot hit thirty. Pete Crow-Armstrong sits at 45 and 41 — he is already there. He plays for the Chicago Cubs.

Say this “Crow-Armstrong’s about to go 30/30 and nobody’s talking about it.”

How Misiorowski actually gets beaten

Jacob Misiorowski has allowed 96 hits all season, which is very few. Of those, 14 were home runs — 15%, against 13% for starters generally, so about the ordinary share. That matters because it tells you HOW he loses: when he is beaten it tends to be one swing rather than a rally, which is the profile of a pitcher nobody strings hits together against.

Say this “What gets him isn’t rallies — 14 of the 96 hits he’s allowed left the park.”

Who is hot and who is not

Baseball is played nearly every day, so form swings hard and fast. Right now the Brewers have won 5 in a row, the Giants have lost 5 straight and Nolan Arenado has got a hit in 13 consecutive games (the record is 56, set in 1941, and is considered unbreakable).

Say this “Brewers are the hottest team in baseball right now.”

Last night

0 results worth knowing, and the individual performances people will mention.

The performances

Two questions that make you sound like you follow this

Both are genuinely open — that's what makes them good questions rather than a quiz.

The words used above

Games back
How far a team trails the leader of its division. Half-games happen because teams play different numbers of games.
Starter vs reliever
A starter pitches six or seven innings once every five days; a reliever throws one inning flat out. Their numbers are never compared directly.
ERA
Runs a pitcher allows per nine innings. The league sits around 4.00; under 3.00 is very good.
Strikeout
Three strikes and the batter is out. For a PITCHER that is the outcome he wants most — nothing can go wrong once the ball is not in play. For a hitter it is the opposite.
30/30
Thirty home runs and thirty stolen bases in one season. Rare because power and speed usually live in different bodies.
Home run
The batter hits it out of the park and everyone on base scores. The loudest thing in the sport.
Stolen base
A runner advances a base on his own, without the ball being hit.
