89 is a number objectively larger than 84. On that we can almost certainly agree, especially when it comes to wRC+ - Weighted Runs Created Plus, a metric that judges Runs Created by hitters in the context of home ballpark, era, and is adjusted to league average.
The number 27 is simply the number 27, though, particularly when 27th is the rank in a category among Major League Baseball’s 30 clubs. During the 2024 regular season, the Cincinnati Reds ranked 27th in wRC+ against both left-handed pitching (84) and against right-handed pitching (89). In other words, they hit slightly better against RHP than against LHP relative to league average, but still ranked as the fourth-worst club in both categories when judged relative to their peer performance.
