The 28-year-old Cabrera -- an All-Star in 2011 and '12 -- is due $10 million this season before he becomes a free agent. He's .250/.310/.399 with nine homers and 38 RBI. A move to San Francisco would likely mean a change to second base, as the Giants already have Brandon Crawford.
The 33-year-old Aviles, is making less this year -- $3 million -- and has a $3.5 million option the Indians can pick up for 2015 with a $250,000 buyout.
Cleveland is second behind the Detroit Tigers in the AL Central while the Giants sit atop the NL West.
