Abreu to be lone initial September addition

PHOENIX -- The Giants announced that Sunday's roster expansion initially will involve only one player: infielder Tony Abreu, who will be reinstated from the 15-day disabled list.

The anticipated handful of players to be promoted for September from Triple-A Fresno won't officially be named until Monday or Tuesday. Fresno's season concludes Monday.

Abreu, who has weathered left knee problems all season, owns a .266 batting average in 34 games with San Francisco.
