ARLINGTON, Texas (AP) — With his team having lost four straight and 12 of its last 18, Boston Red Sox manager Bobby Valentine said the formula for their success is simple.

“Good pitching and timely hitting,” Valentine said after his team’s 9-1 loss to the Texas Rangers on Monday night. “We’re due for it.”

Boston, which has been outscored 33-7 by the Rangers in three games this season, had 10 hits but left eight men on base.

Jarrod Saltalamacchia’s home run in the second inning was the Red Sox’s only run. Saltalamacchia had Boston’s only extra-base hits as he added a double in the seventh inning. Dustin Pedroia went 3-for-4.

Scott Feldman (4-6), starting after Roy Oswalt was scratched with back tightness, kept the Red Sox in check for seven innings. Feldman made a strong case for becoming a starter for Texas, which learned shortly before the game that Colby Lewis will miss the rest of the season because of a torn flexor tendon in his right elbow that will require surgery.

“He kept the ball down and worked off the corners,” Boston third baseman Will Middlebrooks said of Feldman.

Meanwhile, Texas’ bats were booming as the Rangers scored all nine runs in two innings.

Ian Kinsler went 3-for-4 and Craig Gentry went 2-for-4 with an RBI for Texas. Josh Hamilton and Mike Napoli both had two RBIs in the Rangers’ first home game since July 8.

In the third, Texas scored three earned runs against Boston starter Felix Doubront (10-5). Gentry singled and Kinsler walked, then a double steal put the two at second and third. Elvis Andrus runscoring singled to stretch his hitting streak to 11 games. Pedroia overthrew first base to let Kinsler score, snapping a 65-game errorless streak, the longest single-season streak of Pedroia’s career. Hamilton drove in a run with a double and Michael Young’s one-out single scored Hamilton to make it 4-1.

In the sixth, Napoli hit his third home run in as many games, a two-run shot that traveled 416 feet to left field that made it 6-1.
