MLB best and worst win-loss records of all-time could be in jeopardy

We are only about one-quarter of the way through the 2022 MLB season, but we might be looking at some record-breaking performances this year. Some good… some not so good.

First, the New York Yankees tops the majors with a 29-13 (.690 winning percentage). They are on pace to finish the season 112-50. The best win-loss percentage in MLB history was 116-36 by the 1906 Chicago Cubs (.763 winning percentage). Most wins in a season are 116, held jointly by the ’06 Cubs and the 2001 Seattle Mariners. The 1998 Yankees had 114 wins, third most in baseball history. For this season’s Yankees to surpass the all-time record for wins in a season, they will have to go 88-32 the rest of the season; that’s a .733 winning percentage.

On the right side of the ledger, the loss column, the 2022 Cincinnati Reds currently have the major’s worst record at 12-29, a .293 winning percentage. Through games of May 5, the Reds had a 3-22 record (.120 winning percentage) and looked like a sure bet to become baseball’s worst team of all-time. Since then, the Reds have actually had a winning record, 9-7.

The Reds 12-29 record though games of May 24, put them on a pace to finish the season 47-115 (.290). The worst winning percentage in baseball (since 1901) were the 1916 Philadelphia A’s who went 36-117 (.235) that season. Since 1901, there have been 22 teams that have finished a season under .300. Three of those teams have “accomplished” this since 2000:

Detroit, 2003: 43-119 (.265)

Baltimore, 2018: 47-115 (.290)

Detroit, 2019: 47-114 (.292)

To finish above .300 this season, the Reds will need to go 37-84 in their remaining 121 games. To finish with the worst winning percentage in baseball history, the Reds would have to finish with a season-ending record of 38-124 (.235), the worst record in MLB history by percentage points.
