He played in brief parts of five seasons in Major League Baseball, between 1991 and 2000, for the Toronto Blue Jays, Florida Marlins, Milwaukee Brewers and Houston Astros.

Zosky was a collegiate star prior to playing professionally, becoming a member of Fresno State University's athletic Hall of Fame.

[7][8] In addition, Zosky was selected to try out for the United States Olympic baseball team in June of his sophomore season, along with teammates Tom Goodwin and John Salles.

[11] During his junior and final season at Fresno State University, Zosky was named Sporting News and Baseball America All-Americans after posting a .370 batting average.

[16] The initial plan was to have Zosky begin his professional career with the Dunedin Blue Jays of the Single-A Florida State League.

However, citing poor performances by his current shortstops, Double-A manager Barry Foote had Zosky start with the Southern League Knoxville Blue Jays.

[21] That season, he attended his second Major League spring training, and was in competition with Manuel Lee and Rene Gonzales for the starting shortstop position.

He appeared in his first big league game on September 2, against the Baltimore Orioles replacing shortstop Manuel Lee, who had been feeling dizzy and suffering from a stiff neck,[26] in the top of the fourth inning.

Batting ninth in the starting lineup, he collected zero hits in three at-bats, striking out twice against pitchers Ben McDonald and Mike Flanagan.

Though he was expected to unseat Manuel Lee as the starting shortstop for the 1992 Major League season,[32] he began the year with the Triple-A Syracuse Chiefs after posting a batting average of .151 and committing five errors during spring training.

[33] Rather than giving Zosky the backup job, the Blue Jays gave it to non-roster invitee Alfredo Griffin, who had been signed previously.

[2] Following the conclusion of the 1992 minor league season in September, Zosky was promoted to the Toronto Blue Jays, with whom he appeared in eight games.

[3] Following the 1992 regular season, Zosky played for the Tucson Javelinas in the newly formed Arizona Fall League, hitting .326.

[39] To provide insurance in case Zosky floundered, the Toronto Blue Jays signed veteran free agent Dick Schofield, who had played for the California Angels and New York Mets the previous season.

They also re-signed Alfredo Griffin and traded Kelly Gruber and cash to the California Angels for Luis Sojo, who would provide even further insurance in case Zosky failed.

[42][43] Due to his struggles in 1992 – not only did he hit .231, he also committed 27 errors – and his injuries, the Blue Jays began looking beyond Zosky as the future starting shortstop for the team, paying more attention to their other prospect Alex Gonzalez.

[2] Instead, Dick Schofield was the Opening Day starter, though Tony Fernández seized the starting job after his June 11 trade to the Blue Jays from the New York Mets.

[49] Schofield retained a hold on the job, however, and Zosky spent the entire year in Triple-A with the Chiefs, batting .264 with seven home runs and 34 RBI in 85 games, rattling off a 16-game hitting streak at one point.

[52] Zosky made the Marlins Opening Day roster for the 1995 season and on April 29, he played in his first Major League game since October 4, 1992.

Facing Trevor Wilson of the San Francisco Giants, Zosky singled in his first big league at-bat in over two seasons.

He remained with the RiverBats through late July, though after catcher Bobby Hughes went on the 15-day disabled list, the Brewers purchased Zosky's contract and brought him up to the Major League team.

[64] He made his first Major League appearance since May 14, 1995, when, on August 1, 1999, he pinch hit for Brewers pitcher Reggie Harris in the sixth inning and remained in the game, replacing Ronnie Belliard at second base.

In his first Major League game in over four seasons, Zosky went 1-for-2 at the plate, collecting a single in his second at-bat off of Montreal Expos pitcher Dan Smith.

[66] He earned yet another promotion to the Major Leagues on September 5 with starting shortstop Mark Loretta injured and pitcher Chad Fox placed on the 60-day disabled list.

[71] He began his stint in the Astros organization in the minor leagues, playing in 11 games with the Triple-A New Orleans Zephyrs and hitting .273 in 33 at-bats.
