Hunter Renfroe also connected for Boston, and Christian Vázquez had three RBIs.
Bogaerts stated Devers is locked in.
"He can put a team on his back for weeks and months," he said. "He is not the type of man who can just do it for a couple of days. He can ride it for quite a while. It's only a credit to the gift and the work he puts in."
Red Sox right-hander Nick Pivetta (6-0) struck a season-high nine in six innings, settling down after a shaky beginning.

"I was really efficient with my pitch count, was not walking anyone," Smyly explained. "It is pretty difficult to give up five hits and one walk and seven earned runs, but I realized tonight. So, no, I am not happy with the results"
The match was delayed for nearly three hours by rain after the sixth inning.
"We understood exactly what was happening but it was out of the umpires' hands along with the teams, it's the league," Boston manager Alex Cora said. "They tell us we have to play, we perform with. It was tough at the end."
Atlanta jumped out to a quick start with three runs within the first two innings. Ozzie Albies hit an RBI triple and scored on Dansby Swanson's twice from the first. Contreras added a sacrifice fly in the next.
Boston trailed 4-3 before scoring four times in the first time. Devers hit a tiebreaking RBI double and Vázquez added a two-run only with 2 outs, snapping an 0-for-10 skid.
Vázquez also drove in Renfroe using a sacrifice fly in the eighth, giving the Red Sox a 9-4 lead.
"We got back to our fundamentals of a crime and you saw what happened," Cora said. "If we do that on a nightly basis, we can be quite dangerous."
Devers attached for his 14th homer in the fourth, tying it with a two-run shot to centre. However, Riley responded with his 10th of the season in the fifth.
