Tigers legend Justin Verlander's final career start signals the sad end of an era in baseball

When Justin Verlander steps off the mound for the final time in his illustrious career on Saturday, it won’t just be the final start of his Hall of Fame career.

It also signals the end of an era in baseball history: the death of the workhorse starting pitcher.

The leaders on MLB’s all-time pitching lists will likely never change again.

Cy Young has the most wins of all time with 511.

Verlander, who leads active players by a wide margin, has 266.

On the all-time wins list, Verlander is tied for 37th with Bob Feller and Eppa Rixey.

Verlander, who pitched for 21 seasons, won’t be reaching the esteemed 300-win threshold.

Today, bullpens are more prevalent, starters are pulled from games earlier than ever, and pitchers are getting injured as they chase velocity, shortening their careers.

The 300-win pitcher may be a thing of the past.

The active players who trail Verlander on the list? Max Scherzer has 224 wins and is 42 years old, while Gerrit Cole has 162 and is 35.

Cole would have to average 20 wins a year for the next seven seasons to reach 300, meaning he would have to pitch at an elite level through his age-42 season to even have a shot.

While it’s hard to bet against Cole, it’s improbable at best.

Reaching 300 wins would require remarkable longevity and production.
