Four former members of the St. Louis Cardinals are up for a spot in the team's Hall of Fame this year, as reported by Jeff Jones of the Belleville News-Democrat on Wednesday.

Only one player is eligible for induction and the vote is done by the fans. The players are George Hendrick, Brian Jordan, Yadier Molina and Albert Pujols.

Given that only one player can make it, it seems as if it will be quite the contentious vote between Molina and Pujols especially. The vote will last six weeks. 

Here's what you need to know about the quartet heading into the vote:

While not on the field as recently as the others, Hendrick was an excellent player over a 17-year big league career. He spent seven years with the Cardinals, four with Cleveland, four with the California Angels, two with the San Diego Padres and Oakland Athletics and one with the Pittsburgh Pirates.

With the Cardinals, he made two of his four All-Star Games, hitting 122 home runs and driving in 582 runs. He helped the Cardinals win the World Series in 1982.

A former two-sport athlete who also played for the Atlanta Falcons, Jordan spent 15 years in the majors with the Cardinals, Atlanta Braves, Los Angeles Dodgers and Texas Rangers. In seven years with St. Louis, he hit .291 with 84 homers and 367 RBIs. He hit a career-high 36 doubles in 1996 and had 25 homers in 1998.

He never made an All-Star Game with the Cardinals.

One of the best right-handed hitters in major league history, he spent 22 years with the Cardinals, Los Angeles Angels and Los Angeles Dodgers. In parts of 12 seasons with St. Louis, he hit 469 of his 703 home runs and drove in 1,397 runs. A 10-time All-Star with the Cardinals, he also won Rookie of the Year and three MVP Awards.

He also won two World Series titles.

He's a lock for both the Baseball Hall of Fame and the team Hall of Fame, but will Cardinals fans hold it against him that he left for the Angels after the 2011 season?

If they do hold it against Pujols, it might only be to favor Molina, who spent the entirety of his 19 year career with the Cardinals. A career .277 hitter with 176 home runs, he was a 10-time All-Star, a nine-time Gold Glover, a four-time Platinum Glove winner and a two-time World Series champion. He also won a Silver Slugger and the Clemente Award.

The team has brought him back as a special advisor to Chaim Bloom in the front office.
