KANSAS CITY, Mo. -- Ian Kinsler started the 10th inning with a triple off the wall in left-center field, and Michael Young followed with a single to push the Rangers to another narrow win over Kansas City, this time 5-4 to take the four-game series.
Josh Hamilton and Adrian Beltre hit back-to-back homers to erase an early deficit, and Geovany Soto had an RBI double as the Rangers collected nine hits.
The win pushed the Rangers' lead in the American League West to 5 1/2 games over second-place Oakland and eight games over third-place Anaheim, both of which were idle Thursday.
Scott Feldman left the game in the seventh in position to snap a five-game losing streak, but Eric Hosmer took Michael Kirkman deep to forge a 4-4 tie after manager Ron Washington played a lefty-on-lefty matchup.
Jeff Francoeur homered in the second to give the Royals a 1-0 lead, and they tacked on two more in the third with an RBI triple by Alex Gordon and a single by Salvador Perez.
But the Rangers scored three times with one out in the fourth, a rally that started with a single by Young. Hamilton followed with his baseball-leading 39th homer of the season, and Beltre knocked No. 30 as the Rangers went back-to-back for the ninth time this season.
It was the fourth time for Beltre to follow a Hamilton homer.
Soto doubled home David Murphy in the seventh to stake the Rangers to a 4-3 lead, and Feldman returned to get the first out of the seventh. He exited having retired the final 11 batters he faced.
Tanner Scheppers, Mike Adams (4-3) and Joe Nathan allowed only two hits in 3 1/3 scoreless innings of relief.
