The Gateway Grizzlies are members of the Frontier League, a professional, independent baseball organization featuring teams that have no affiliation with major league baseball.  The league was formed in 1993, and it’s the oldest current running independent league.

Since the Grizzlies inception in 2001, the organization has sent more than 30 players to MLB affiliates, and 18 players signed since manager Phil Warren took over as skipper in 2007."That is something we take a lot of pride in," Warren said. "The more players that get signed out of here, the more attractive this organization becomes."

Warren, now one of the most successful managers in Frontier League history, preaches team dynamics and intense play. “9 Hard. Every Night.” has become the unofficial team mantra – and is certainly evident in the club’s play.

As of February of 2016, the Grizzlies have seen 37 of their players signed into a major league organization either while playing for the organization or after playing for the team. 

Scott Patterson became the first former Gateway player to make it to the major leagues when he debuted with the New York Yankees in 2008.  Patterson also saw action with the San Diego Padres that season.  He has no record and a career ERA of 1.93 in the major leagues.  He has appeared four times in relief.

Many Grizzlies players have reached high levels of affiliated ball. In 2011, Aaron Shafer and Ryan Khoury both reached high levels after getting picked up by affiliated clubs.  Khoury appeared at Triple-A Pawtucket after getting picked up by the Red Sox in mid-June, and Shafer excelled in the Atlanta Braves system, dominating High-A Lynchburg and reaching Double-A Mississippi.
 
In 2012, Vladimir Frias was picked up late in the season by the Chicago Cubs, Logan Mahon was signed by the Orioles and John Shelby was signed by the Chicago White Sox immediately after the season ended.
 
“There are two goals here: to win a championship and get picked up by an affiliated team,” Warren remarked. “The players don’t come here and play because of the money...they are all holding on to the same dream."
