When the Arizona Fall League camps open in mid-September, the Seattle Mariners will send seven players - from first-round draft pick Danny Hultzen to minor league shortstop Nick Franklin - to participate.
For Hultzen, the left-handed pitcher taken with the second pick in the June draft, it will be his first experience pitching professionally. For most of the others, it will be a higher caliber of competition than they've faced before.
One player for whom that will not be the case is catcher Adam Moore, who lost the 2011 season in Seattle to a knee injury.
The Mariners will play with the Peoria Javelinas, with the season beginning in early October. The full contingent of Seattle players: Hultzen, Moore, Franklin, LHP Brian Moran, RHPs Forrest Snow and Steven Hensley, and outfielder Chih-Hsien Chiang.
