Alright, it’s time to have the conversation. That’s right, it’s time to talk about cluster luck and the Mariners run differential. After their ugly loss yesterday afternoon, Seattle’s run differential fell to -58 on the year despite an actual record that sits seven games over .500. So with just a day left before the July 30 trade deadline and the Mariners in the thick of the AL Wild Card race, let’s talk about whether they’ve been extremely lucky or if they’re actually good.
Every year there are run differential overperformers and underperformers. This year, the Blue Jays have gone 50-48 despite a fantastic +85 run differential.
