File-This July 25, 2012 file photo shows Chicago Cubs pitcher Ryan Dempster pitching during the second inning of a baseball game against the Pittsburgh Pirates in Pittsburgh. The Texas Rangers have obtained Ryan Dempster from the Chicago Cubs, a move to fortify their rotation for the stretch run. The AL West leaders sent minor leaguer infielder Christian Villanueva and pitcher Kyle Hendricks to Chicago as part of a deal Tuesday July, 31, 2012. Dempster, who had power to block deals, had refused to approve a trade to Atlanta last week. The 35-year-old right-hander was 5-5 with a 2.25 ERA in 16 games for the Cubs and can become a free agent after the season. (AP Photo/Gene J. Puskar, File)
