Jason Varitek drove in the go-ahead run with a double in the ninth inning, J.D. Drew homered and the Boston Red Sox rallied to beat the Los Angeles Angels 4-3 on Tuesday night.

Drew led off the ninth with a single against Scot Shields (1-3) and scored one out later when Varitek lined the right-hander's 1-2 pitch to right-center.

Ramon Ramirez (4-0) pitched a hitless eighth inning for the victory and Jonathan Papelbon got three outs for his ninth save in as many chances.

Jered Weaver, coming off the first complete-game victory of his four-year career, allowed a run and four hits over seven innings and left with a 3-1 lead before the bullpen squandered it away.

The Red Sox loaded the bases with one out in the eighth against Jose Arredondo, and Darren Oliver came in to face the still-homerless David Ortiz _ who was 2 for 9 against the left-hander. Oliver hit Ortiz on the left wrist with a 1-2 pitch to force in a run, and Jason Bay grounded out against Shields to drive in Jacoby Ellsbury with the tying run.

The Angels' bullpen has been scored on in 20 of 29 appearances with five blown saves, a 2-9 record and a major league-worst 6.90 ERA.

Justin Masterson allowed two runs and five hits over six innings and struck out four in his fifth start since replacing the injured Daisuke Matsuzaka in the Boston rotation.

The Red Sox began their six-game West Coast trip by placing first baseman Kevin Youkilis on the 15-day disabled list _ retroactive to May 5 _ because of a strained oblique on his left side. Reigning AL MVP Dustin Pedroia missed his first game of the season because of a groin strain.

The two-time defending AL West champion Angels took a 2-1 lead in the third on a sacrifice fly by Maicer Izturis.

The Angels loaded the bases in each of the first two innings, but all they had to show for it was a sacrifice fly by Kendry Morales. Torii Hunter made it 3-1 in the seventh with a two-out RBI single against Manny Delcarmen. The run was unearned because of a throwing error by third baseman Mike Lowell on Chone Figgins' leadoff grounder.

Both dugouts received a warning from plate umpire Jim Joyce in the third inning after Masterson threw a pitch behind Hunter _ who was backed off the plate by his previous offering.

The last time the teams met at Angel Stadium on April 12, Boston's Josh Beckett threw a pitch over the head of Bobby Abreu a split-second after time was called, precipitating a bench-clearing incident that led to the ejections of two Angels players, manager Mike Scioscia and hitting coach Mickey Hatcher. Beckett was handed a six-game suspension that was appealed down to five, and didn't miss a turn in the rotation.

Notes:@ Ortiz was homerless in his first 119 at-bats. His longest previous drought from the start of a season since joining the Red Sox in 2003 was 34 at-bats in 2008.
