Spending the entire 2002 season at Double-A New Haven, starting games at third, first and in left, Gall led the Eastern League in hits (166), doubles (45), extra-base hits (68) and total bases.
His stock as a prospect continued to rise the following season, as the Cardinals named him the organization's Minor Player of the Year for a second straight year in 2003, after hitting a combined .314 with 19 homers and 85 RBI between Tennessee (AA) and Memphis (AAA).
Gall hit a career-high 22 home runs at Triple-A Memphis in 2004, hitting .292 while driving in 84 RBI and the fans of Cardinal Nation were wanting the young outfielder promoted to St. Louis to add some power off the bench and to be one of the outfielders of the future.
Fans got their wish in 05, as Gall made his Major League debut in July last season, when Larry Walker was placed on the DL and doubled in his first at bat against former St. Louis Cardinal, Woody Williams.
With St. Louis last season, John batted .357 (5-14) with one home run and three RBI. Cardinals' Manager Tony La Russa showed the same confidence in the young slugger as the fans had, by adding him to the post season roster.
In his first Major League postseason experience he had one pinch at-bat in Game 2 in the Division Series and did not appear in the League Championship Series against the Houston Astros.
In spring training this year, Gall was given an outside shot at making the big club, but after hitting just .207 with one home run and 10 RBI in 25 games, the once very promising prospect was sent back to Memphis to start the 06 season.
Gall was hitting .282 with six home runs and 34 RBI in 82 games for Memphis this season before being placed on waivers Monday.
Gall did manage to appear in eight games with St. Louis this season, while another outfielder, Larry Bigbie was on an injury rehab assignment in Memphis. In eight at bats Gall hit .250 with no home runs and one RBI for the Cardinals and his stay with St. Louis was short lived.
Utility player Shawn Garrett was signed and activated in place of Gall. Garrett, who was released earlier this year by Scranton-Wilkes Barre of the International League, went 0-for-3 in his Redbirds debut.
