50 Mookie Betts RF

Betts is out of the lineup for Sunday's game against the White Sox, Pete Abraham of The Boston Globe reports.

Betts will sit out for just the second time all season and the first time since April 7 as the Red Sox build in some rest for the star outfielder in the midst of a stretch of 12 games in 12 days. J.D. Martinez will shift to the outfield as a replacement for Betts while Steve Pearce handles Martinez's usual duties as designated hitter.

Betts went 2-for-4 with a solo home run in Tuesday's 5-1 win versus Oakland.

Betts continued his current hot stretch at the plate as he is now 12-for-24 with four doubles and two home runs over the last six games. The 26-year-old is now slashing .295/.394/.527 with six home runs and 15 RBI as he appears to be rounding into form, though having only one steal through the first month of the season remains a bit of a concern.

Betts went 2-for-5 with a solo home run in a 2-1 loss to the Rays on Saturday.

The 2018 AL MVP started horribly, but he's 13-for-30 (.433) with two homers and six RBI in the last seven games. He still has more work to do in the average category, but considering the slow start, owners should be just fine with his .267/.370/.485 slash line along with five home runs, 13 RBI and 20 runs. The biggest concern, though, is the lack of steals. Betts swiped 30 bags a year ago, but has just one stolen base through a month of 2019. While he may get more opportunities to steal as he gets on base more during the final five months, Betts having one stolen base attempt in 27 games is still a little alarming.

Betts went 2-for-4 with two doubles, an RBI and a run scored Thursday against the Tigers.

Betts tacked on an insurance run in the fourth inning after doubling home a run. Following a disappointing start at the plate this season, the reigning American League MVP has come alive of late and has now secured a base hit in six of his past seven matchups. Five of those performances have been multi-hit games for Betts. He'll look to carry this momentum into Boston's weekend series against Tampa Bay.

Betts went 2-for-4 with a walk, a double, an RBI and two runs scored in Wednesday's 11-4 win over the Tigers.

Betts' double would have been a home run in any park that didn't have a 37-foot wall in left field. He's on a six-game run that's raised his average 50 points to .250. During that stretch, the reigning AL MVP is 9-for-22 (.409) with six walks, a home run, four RBI and five runs scored.
