Rapid Reaction: Angels 4, Red Sox 2

BOSTON -- The Red Sox’s season-long struggle with leaving men on base persisted Monday night in the team’s 4-2 loss to the Los Angeles Angels of Anaheim.

On the night, Boston left 12 men on base and went 1-for-14 with runners in scoring position.

The Red Sox’s first run came in the fourth inning after Mookie Betts worked a two-out walk and advanced to third on a single by Christian Vazquez. Brock Holt followed Vazquez with a single of his own, scoring Betts and extending his hitting streak to a career-high 12 games.

Two strong opportunities to score in the middle innings passed the Red Sox by. David Ortiz led off the fifth with a double but was left stranded at third. Next inning, Betts, Vazquez and Holt each reached to load the bases with one out before Dustin Pedroia grounded into an inning-ending double play.

In the ninth inning, Boston put runners at first and third with no outs, but only managed one run on a Yoenis Cespedes (0-for-5 at the plate) fielder’s choice.

C.J. Wilson got the win for the Angels, walking five and giving up five hits in 5 1/3 one-run innings.

Workman does his job: Pitching for the first time since giving up the winning run in relief in the team’s 19-inning loss to the Angels on Aug. 9, Brandon Workman put together a quality outing, going seven innings for the third time this season and allowing two runs.

Workman gave up six hits on the night and walked two while striking out five. The loss dropped him to 1-7 on the season.

It was Workman’s first solid outing since July 8.

Trouble for Taz: Pitching the eighth, Junichi Tazawa was charged with two errors on one play in the process of giving up two runs.

With the bases loaded and one out, Howie Kendrick grounded a ball back to Tazawa that he had bounce off his glove and away from him. After retrieving the ball, Tazawa rushed the throw home and hit a sliding Chris Iannetta in front of the plate. The ball then bounced toward the Red Sox dugout, allowing Calhoun to come around and score as well.

After giving up only eight runs from March through June, Tazawa has given up 12 between July and August.

Vazquez shows off his arm: On two separate attempts, Angels base runners tried to swipe second base from the Red Sox. On both attempts, Vazquez gunned them down.

Erick Aybar was caught stealing in the fourth while Vazquez gunned down David Freese on a pitch-out in the seventh. Freese still had yet to go into his slide before Xander Bogaerts was waiting for him with the ball at second.

Vazquez has now caught six of the 14 runners who have attempted to steal on him in the majors.

Web Gem: Will Middlebrooks leaped to his right to snag a John McDonald liner out of the air in the ninth inning.

Bradley's night: Jackie Bradley Jr. went 0-for-5 with two strikeouts in his first game with Triple-A Pawtucket after being optioned Monday afternoon.

Rehabbing outfielder Allen Craig also made an appearance for the Paw Sox, going 0-for-2 with a walk serving as their designated hitter as he recovers from a left foot sprain.
