Jim Thome accepted a trade from the Twins on Thursday night to return to the Indians, the team he started with and one hoping its career home run leader can help it run down the first-place Tigers in the AL Central, according to an ESPN.com report.

The Diamondbacks have traded second baseman Kelly Johnson to the Blue Jays for infielders Aaron Hill and John McDonald Johnson, eligible for free agency after the season, has struggled at the plate this year, hitting .209 with 132 strikeouts and 18 homers. Hill, who will fill Johnson's spot at second, is hitting .225 but was second among all second basemen with 62 homers from 2009-10. McDonald is expected to help Willie Bloomquist at shortstop with Stephen Drew on the DL with a broken right ankle. McDonald hit .250 in 65 games with Toronto this season.

The Rockies have officially acquired Drew Pomeranz, completing their trade with the Indians for pitcher Ubaldo Jimenez.
