HOUSTON -- Several of the Astros' top prospects, including pitcher Jarred Cosart, first baseman Jonathan Singleton and center fielder George Springer, are among the seven players the club will send to participate in the Arizona Fall League this season.
Also playing in Arizona will be pitchers Chia-Jen Lo and Alex Sogard and infielders Bobby Borchering and Jiovanni Mier, who will be on the taxi squad and activated only on Wednesdays and Sundays as he comes off an injury-filled 2012.
The Astros' contingent is assigned to the Mesa Solar Sox, which is managed by Rodney Linares, the skipper at Class A Lancaster. The season will begin Oct. 9 and end Nov. 17.
Each Major League organization is required to provide seven players. All Triple-A and Double-A players are eligible, provided they are on Double-A rosters no later than Aug. 15. Each organization is permitted to send two Class A Advanced-level players in addition to the current allowance of two "A exempt" players (who are under contract as of Aug. 15). Foreign players are allowed as long as the player is not on his native country's primary protected-player list.
No players with more than one year active or two years total of credited Major League service as of Aug. 31 (including Major League disabled-list time) are eligible, except a team may select one player picked in the most recently concluded Major League Rule 5 Draft.
