Cubs add five to 40-man roster

Prospects protected, two spots open for Rule 5 Draft

CHICAGO -- The Cubs added outfielder James Adduci, catcher Welington Castillo and pitchers John Gaub, Blake Parker and Rafael Dolis to the 40-man roster on Friday.

Teams had to set their 40-man rosters by 11 p.m. CT Friday in preparation for the Rule 5 Draft, which is held Dec. 10 at the Winter Meetings. The Cubs' roster is now at 38.

Adduci, 24, hit .300 with 63 runs, 35 stolen bases, 21 doubles, four triples, four homers and 51 RBIs in a career-high 131 games with Double-A Tennessee last season. The left-handed hitter had the third-most hits of any player in the Southern League, falling short of the leader by two hits.

A native of Evergreen Park, Ill., Adduci was acquired from the Florida Marlins in September 2006. He has a .283 career batting average.

Gaub, 24, posted a 2.83 ERA in 26 games at Double-A Tennessee, striking out 40 over 28 2/3 innings and holding hitters to a .188 average. He was promoted to Triple-A Iowa in late June and appeared in 26 games, compiling a 1.72 ERA. The lefty struck out 40 and walked 16 over 31 1/3 innings.

Gaub, who struck out 100 over 64 innings in 2008 for the Indians' Class A Lake County team, also pitched for the Mesa Solar Sox in the Arizona Fall League. He appeared in 10 games, but didn't fare as well, giving up 10 earned runs for a 9.31 ERA in 10 games. He did strike out 15 over 9 2/3 innings.

Parker, 24, a 16th-round pick in the 2006 Draft, gave up two runs and struck out 19 over 12 1/3 innings at Double-A Tennessee, then was bumped up to Iowa, where he compiled a 3.00 ERA in 45 games. The right-hander fanned 58 in 51 innings.

He also pitched for the Solar Sox in the AFL, striking out 11 in 12 innings over 11 games.

Dolis, 21, appeared in 27 games and made 25 starts for Class A Daytona, going 3-9 with a 3.79 ERA. He struck out 75 over 99 2/3 innings. Teams hit .221 against him. The right-hander had a strong first half, giving up 15 earned runs over 46 2/3 innings for a 2.89 ERA.

Castillo, 22, batted .232 in 95 games at Tennessee, hitting 11 home runs and driving in 39. He began the year with a .278 career Minor League batting average. Castillo played four games with the Mesa Solar Sox in the Arizona Fall League, but a sore knee forced him to exit early. He hit .357 with Mesa, including a home run.

Last year, the Cubs lost left-handed pitcher Donnie Veal to the Pittsburgh Pirates in the first round of the Rule 5 Draft.
