Braves’ upcoming opponent: About the Red Sox

Braves' opponent: Boston Red Sox

Keep an eye on: A testy team. First Wade Miley got into a dugout confrontation with manager John Farrell after he was lifted from Thursday night's game. Then on Friday, the Red Sox blew a seven-run lead to the Blue Jays to fall eight games under .500. The Braves had lost five in a row entering Sunday. Free agent signee Pablo Sandoval has largely been a disappointment so far hitting just .251 through 55 games and playing shoddy defense. And Big Papi, David Ortiz, is hitting .226 on the season and just went 69 at-bats between home runs when he hit one Thursday, his longest home run drought in four years.

Who's hot: Sandoval was 8-for-23 (.348) with two doubles, a home run and six RBIs in his previous six games entering Sunday.

Who's not: Mike Napoli was 1-for-his-past-20 with 10 strikeouts after striking out with the bases loaded in the eighth inning Friday night and hasn't started since.

Braves connection: Reliever Anthony Varvaro, who signed with the Red Sox this past offseason, was designated for assignment on April 29 after posting a 4.09 ERA in nine games. He was claimed off waivers by the Cubs and then designated for assignment by them as well.

In the news: Center fielder Mookie Betts sprained his lower back Friday night running into the bullpen wall at Fenway Park trying to make a catch. He is considered day-to-day but did not start Saturday or Sunday.
