Long pants have been a staple of baseball uniforms since the earliest days of the sport in the mid-1800s. While styles and lengths have evolved over time, MLB has always required players to wear long pants during games. There was never an outright ban on shorts or a specific year when long pants became mandatory.
History of Pants in Baseball
In the 1840s and 1850s when baseball was first developing, players wore loose-fitting long trousers made of wool. Some teams, like the New York Knickerbockers, wore pants that stopped at the knee called "knickerbockers." This allowed more freedom of movement for fielding and running compared to full-length pants.
By the late 1800s, most players wore full-length wool uniform pants. Pants became tighter fitting over time. The Cincinnati Red Stockings were the first professional team in 1869, and they wore knicker-style pants with long socks. When the National League was founded in 1876, long pants were standard across all teams.
The length and style of pants continued to evolve in the early 1900s. Some players began wearing their pants lower and covering their shoetops. Others wore shorter pants with long socks. Stirrup socks became popular, showing bare skin between the sock and pant leg. But long pants remained required.
Even when uniform styles relaxed in the 1970s, including the introduction of polyester pullovers and vest jerseys, long pants were still mandatory according to MLB regulations. There was never an outright ban on shorts in games. Pants have simply been the tradition since baseball's beginnings.
Protection from Sliding
One major reason baseball players have always worn long pants rather than shorts relates to sliding. When running the bases, players will often slide feet first into a base. This allows them to avoid dangerous collisions and extend their reach to the base.
Sliding on the dirt and gravel of the infield can cause significant abrasions on bare skin. Long pants help protect players' legs when sliding. The sturdy fabric reduces skin damage.
Many players today also wear sliding pads under their pants for extra protection. But even without sliding pads, long pants are far safer for slide protection than bare legs or shorts.
Protection from Cleats
When sliding into a base, a runner's cleats will often come up and make contact with the fielder's legs. Long pants add a layer of protection against those cleats. Shorts would leave fielders vulnerable to gashes or bruising during slides.
So pants protect the fielder covering a base against the slider's cleats. They also protect the slider if a fielder ends up stepping on or brushing against the slider's legs when applying a tag. For both offensive and defensive players, long pants prevent cleat-related injuries.
A Professional Look
Since their earliest days, baseball uniforms have sought to project professionalism and class. Even though baseball uniforms have become more athletic and casual over time, they still maintain a certain dignified aesthetic.
Long pants are seen as embodying that professional team sport look more than shorts. NFL, NBA, NHL, and MLS players all wear long pants during games for a similar reason. Shorts are associated more with solo sports like track, tennis, and golf.
So long pants are partly just tradition and now expected as part of proper baseball uniforms. Fans and officials alike see long pants as essential to the sport's identity and heritage.
Shorts in Baseball
Outside of those 1976 games, shorts have not been permitted during official MLB games. Baseball pants have evolved in length and fit, but they have remained long pants since the earliest days of the sport.
However, shorts are common in baseball practices, warmups, batting cages, and casual contexts. It is only during official games that long pants are strictly required by MLB regulations.

Conclusion
Long pants have been standard in Major League Baseball since the earliest professional teams in the 1870s. The classic baseball uniform has always included long pants rather than shorts.

MLB has never outright banned shorts in games, but long pants are deeply ingrained as proper baseball attire.
