So far, no major-league transactions beyond the Esmil Rogers deal, but the Indians have been active in minor-league free agency...
Signed UT Nate Spears to a minor-league deal
Spears was drafted by the Orioles in 2003, spending most of his younger years as either a full-time shortstop or second baseman. He was dealt to the Chicago Cubs organization in 2006 for Corey Patterson, and although he made it as high as AAA Iowa, he didn't get a shot in the big leagues with the Cubs. He became a minor-league free agent after the 2009 season, signed with the Red Sox, and has spent most of the of the last three seasons as a utility man in the minors, playing all over the diamond, including a couple short stints on the mound. Last season in Pawtucket he played mostly at third and second, though he also played some at first (5 games), shortstop (1 game), and the outfield (3).
Spears isn't much of a hitter, which is why he's only gotten 8 major-league plate appearances. Still, he's a valuable player to have on a minor-league roster, and I'm fairly certain that Terry Francona had a lot to do with him coming to Cleveland.
UT Brent Lillibridge refused outright assignment
Speaking of utility players, Lillibridge is now a free agent after refusing his outright assignment. With the Indians' acquisition of Mike Aviles and the presence of both Jason Donald and Cord Phelps on the roster, Lillibridge wasn't likely to make the 25-man roster with the Indians, especially now that he's off the 40-man roster.
Sent RHP Fabio Martinez outright to Columbus (AAA)
That Martinez was sent outright to Columbus' roster is a misnomer, since he's only gotten as high as high-A ball, and has struggled to boot. Martinez' stuff is outstanding, but his control has been awful, so perhaps a shift to the bullpen will help.
