The Giants recalled Matos from Triple-A Sacramento on Tuesday.
The 22-year-old was optioned to Sacramento in late July but is back with the Giants for the final month of the season. Matos has played in 40 games across his two previous stints in the majors this season and has a .217/.238/.333 slash line with four homers in 143 plate appearances. The right-handed bat of Matos could work as a short-side platoon partner of Grant McCray in center field.
