Pitchers and catchers report to the Cubs' camp in Mesa, Ariz., on Feb. 13, with the first workout the next day. Position players are scheduled to report Feb. 18, and the first full-squad workout will be the next day at Fitch Park.
Fox, 37, has not pitched since 2005, when his season ended because of a right elbow strain. This is his second turn with the Cubs after making 11 relief appearances in 2005. In 214 career relief appearances, Fox has a 3.57 ERA.
He is one of seven pitchers invited, joining left-handers Ed Campusano, Geoff Jones and Les Walrond and right-handers Esmailin Caridad, Jose Ceda and Mike Smith.
Campusano, 25, was re-acquired by the Cubs on Oct. 10, after he missed last season recovering from left elbow surgery while with Detroit. Originally signed by the Cubs as a non-drafted free agent in July 2001, he produced a 3.17 ERA and 224 strikeouts in 109 Minor League games, including 19 starts.
Caridad, 22, was signed by the Cubs as a non-drafted free agent on Dec. 19. The right-hander spent 2007 with the Hiroshima Carp. He was 1-2 with a 4.02 ERA in 25 relief appearances for the Carp's Dominican club and later appeared in two Central League contests.
Smith, 30, spent last season with Triple-A Memphis in St. Louis' farm system and finished second in the Pacific Coast League with 127 strikeouts in 159 2/3 innings. Signed by the Cubs as a Minor League free agent on Nov. 20, he has appeared in the Majors with Toronto (2002) and Minnesota (2006), pitching in 15 games (seven starts).
Jones, Ceda and Walrond were all in the Cubs' Minor League system last year. Jones, 28, spent most of the season at Double-A Tennessee, posting a 4-2 record and 1.02 ERA in 39 relief appearances. Ceda, 20, enters his third season with the Cubs after being acquired from San Diego on June 31, 2006, in exchange for Todd Walker and cash considerations. He held opponents hitless in his final 23 1/3 innings for Class A Peoria last season. Walrond, 31, went 11-5 with a 4.77 ERA in 27 games (24 starts) for Triple-A Iowa. This will be the third straight invite to Chicago's Major League camp.
