As their preparations for Opening Day continue, the Cubs sent seven players to Minor League camp on Friday in their latest round of cuts.
Right-handed hurlers Jeff Gray and Marcos Mateo, along with left-hander John Gaub and outfielder Jim Adduci, were optioned to Triple-A Iowa.
Adduci turned in a strong spring for the Cubs, batting .357 in 42 at-bats.
Mateo appeared in seven games this spring, allowing seven earned runs in 7 2/3 innings. Gaub also appeared in seven Grapefruit League games, compiling a 7.04 ERA.
Infielders Darwin Barney, Bobby Scales and backstop Robinson Chirinos were also assigned to Minor League camp.
Barney, who hit .293 over two Minor League stops last season, batted .286 this spring. Scales compiled just three hits in 25 at-bats this spring. Chirinos showed some pop this spring, as his four hits included one home run and one double.
The moves left the Cubs with 33 players on their roster -- 15 pitchers, three catchers, nine infielders and six outfielders.
