Rangers 18, Red Sox 3: Texas clubbed six homers - including two by Mike Napoli - and Colby Lewis pitched seven strong innings as the Rangers improved to 4-0 on the road for the first time in 20 years.

Texas owns the American League's best record at 9-2, while Boston dropped its second straight to fall to 4-7.

Lewis (2-0) yielded a two-run homer to Dustin Pedroia in the first, but was nearly unhittable after that. He fanned seven and walked none in lowering his ERA to 1.83.

Texas sent 10 men to the plate in a four-run second. Napoli highlighted the outburst, golfing an 0-2 slider over the Green Monster to tie it 2-2. Michael Young hit a sixth-inning solo homer, and Josh Hamilton and Adrian Beltre crushed back-to-back homers in an eight-run eighth that also featured Nelson Cruz's two-run blast.

It was the fifth homer this season for Hamilton, who has 11 RBIs in 11 games.

Red Sox ace Jon Lester (0-2), knocked out after 2-plus innings, allowed seven earned runs on eight hits and four walks.
