ARLINGTON -- Adrian Beltre’s 399th career home run and another strong outing from Colby Lewis helped the Rangers open their homestand with a 8-2 victory over the Royals on Monday night at Globe Life Park.

Royals starter Danny Duffy took the loss, getting himself into trouble with a bout of wildness in the second inning. Duffy walked the first three hitters and the Rangers ended up scoring four runs.

Beltre launched a two-run home run off of Duffy in the fourth. Thomas Field, called up from Triple-A Round Rock, belted his first Major League home run for the Rangers in the seventh. Prince Fielder hit his third home run of the season in the eighth.

“We know they are a good team. They have good pitching and defense, and speed on the bases,” Beltre said. “Colby did a great job and we took advantage of their starter, Duffy, he was a little wild. It’s always nice to win the first one. We need to play better at home.”

Lewis went seven innings and allowed one run on three hits and two walks with five strikeouts. Lewis is now 2-0 with a 0.86 ERA in three starts in May, and he’s 3-2 with a 2.40 ERA in seven starts on the season.
