ARLINGTON, Texas (AP) - Ian Kinsler hit a leadoff home run and Mitch Moreland launched a 463-foot shot, sending Ryan Dempster and the Texas Rangers past the Minnesota Twins 9-3 Saturday for their fourth straight win.

Kinsler homered in the first, hit a bases-loaded triple in the third inning that made it 9-0 and also singled.

Dempster allowed two runs in six innings and improved to 3-1 since he was acquired from the Cubs on July 31. He was 5-5 with Chicago.

Brian Duensing (3-9) gave up a career-worst nine runs in 2 1-3 innings as the Twins lost their fifth in a row.

Justin Morneau went 4 for 4 with a home run for Minnesota, which has dropped 14 of 16 overall.
