I was mostly kidding. I'm also sure people have done the math.
Haha I can't even tell what year this was. 2003 with Thome I guess?

They're already grumbling in Philadelphia. The Phillies, after a strong offseason that has elevated them to the status of NL East favorites, have started their exhibition season by losing four of their first five games. Phillies fans, not exactly the most patient and supportive group around, are beginning to gripe about the poor start on talk radio and the internet.
But I'm here to put Philadelphians' minds at ease, at least until next month. Even if the Phillies play this way for the rest of March, it won't have any bearing on whether they'll be playing in October. Aside from dugout chatter, power ballads, and Yogi Berra quotes, there is nothing less meaningful in the baseball world than spring training records.
From the Athletic in 2018
Our analysis found an R² of 5 percent. That means just 5 percent of the variance in regular-season win-loss records is predicted by spring training records. In other words, they’re almost completely unrelated to one another.
For example, from 2008-2011 the Phillies tied for the best regular-season record in baseball at 384-264 (.594). Yet, in that span they were below .500 in the spring.
