A Major League Baseball roster is a roster of players able to play for their respective Major League team. There are two types of rosters, the 25-man roster and the 40-man roster.

Also called the active roster, the 25-man is composed of 25 players who are playing for their Major League team. They are the starting eight position players, pitchers, and reserve players on the team. Players on the active roster are also on the 40-man roster. These players are generally the only ones who dress in uniform and are the only ones who may take the field in a game at any time. Typically, only players on the 25-man roster, and players who are on the disabled list but were on the 25-man roster, travel on road trips with the Major League team.

Beginning in the 2012 season, teams will be allowed 26-man rosters for scheduled "day-night" doubleheaders—two games scheduled on the same day, but with the stadium cleared between games, and separate tickets sold for each game.

In addition, Cena has also won the WWE United States Championship three times, and is a four-time Tag Team Champion, having held the World Tag Team Championship twice (once each with Shawn Michaels and Batista), and the WWE Tag Team Championship twice (once each with David Otunga and The Miz).

He also has the fourth highest number of combined days as WWE Champion behind Bob Backlund, Hulk Hogan and Bruno Sammartino.

Cena started his professional wrestling career in 2000, wrestling for Ultimate Pro Wrestling, where he held the UPW Heavyweight Championship. In 2001, Cena signed a contract with the World Wrestling Federation (WWF) and was sent to Ohio Valley Wrestling (OVW) where he held the OVW Heavyweight Championship and the OVW Southern Tag Team Championship (with Rico Constantino).

Randal Keith "Randy" Orton (born April 1, 1980) is an American professional wrestler and actor. He is signed to WWE wrestling on its SmackDown brand. Orton is a third-generation professional wrestler; his grandfather Bob Orton, Sr., father "Cowboy" Bob Orton, and uncle Barry O all competed in the professional wrestling industry.

Before being promoted to the main World Wrestling Federation (WWF, now WWE) roster, Orton trained in and wrestled for Mid-Missouri Wrestling Association-Southern Illinois Conference Wrestling for a month. He was then sent to Ohio Valley Wrestling (OVW), where Orton held the OVW Hardcore Championship on two separate occasions.

After signing with WWF, Orton became a member of the stable Evolution, which quickly led to a WWE Intercontinental Championship reign, his first title with the company. Orton also acquired the moniker "The Legend Killer" during a storyline where he began disrespecting Hall of Famers and physically attacking veterans of the industry outside of appropriate restrictions. At age 24, Orton became the youngest person ever to hold the World Heavyweight Championship. With this win, Orton departed from Evolution and a feud with his former stablemates began. In 2006, Orton joined forces with Edge in a tag team known as Rated-RKO. Together, Orton and Edge held the World Tag Team Championship. After the team disbanded, during mid-2007, Orton gained two WWE Championship reigns in one night. Orton formed the group The Legacy with Cody Rhodes and Ted DiBiase in 2008, however, they would disband in 2010 with Orton returning to singles competition. Overall, Orton has won eleven total championships in WWE, including being a nine-time world champion, having won the World Heavyweight Championship three times and the WWE Championship six times. He is also the winner of the 2009 Royal Rumble match.
