The Astros made their first significant round of roster cuts Monday, sending 13 players to minor league camp.

Pitchers David Carpenter, Cesar Carrillo, Jorge De Leon, Arcenio Leon and second baseman Jimmy Paredes were optioned to minor league camp as dictated by their status on the 40-man roster, which is unchanged.

The minor league invitees — pitcher Douglas Arguello, infielders Koby Clemens, Brian Dopirak, Jiovanni Mier and Jose Carlos Thompson, outfielders Jon Gaston and J.D. Martinez and catcher Rene Garcia – were reassigned to minor league camp.

The cuts came one day after the Astros finished the bulk of their split-squad games with five in the first two weeks and one in the last two weeks. The need for the enlarged roster waned, and regulars will start getting more and more of the playing time.
