A strong pitching matchup is on tap as the visiting Minnesota Twins look to complete a three-game series sweep of the Boston Red Sox on Sunday afternoon.

Standing in the way of Bailey Ober (5-2, 3.63 ERA) and the Twins is fellow right-hander Sonny Gray (5-1, 2.93), who has allowed just two runs and struck out 17 batters in 17 innings across a three-game win streak.

Gray pitched six innings of one-run ball with a season-high nine strikeouts last Monday against the Kansas City Royals. It was his second straight outing of that length.

"The same as we've seen (in) the last two outings," Red Sox interim manager Chad Tracy said of Gray's recent stretch. "Just in complete control, in and out, up, down, changing speeds. Had a nice front-door sinker, running it back on lefties, catching the inside corner. He was sensational."

Gray, who is 3-6 with a 5.63 ERA in 11 career starts against Minnesota, again will look to play the role of stopper for his team after the Twins started the series with 8-6 and 4-2 victories.

On Saturday, the Red Sox were limited to five hits, but a ninth-inning rally after loading the bases was cut short. It was the 22nd game this season in which they were held to two or fewer runs (2-20).

"We gave ourselves chances and had a big, big shot there," Tracy said.

Ceddanne Rafaela had Boston's lone RBI hit on a double in the fourth inning.

Willson Contreras was 2-for-3 and scored a run, but he also was at the center of a minor benches-clearing altercation after he slowed up before running into Twins catcher and former Chicago Cubs teammate Victor Caratini covering the plate.

"It wasn't anything malicious or anything at all, it was not bad intention," Contreras said. "For him to get that mad at that was kind of surprising. For the benches to empty, that was surprising as well."

The Twins claimed the series and won their third straight on Saturday. Trevor Larnach's 4-for-5 day with a double and two runs helped make a winner out of Taj Bradley, who returned from the injured list to pitch five innings of one-run ball.

The victories have come in different ways for Minnesota. It scored five unanswered runs to finish Friday's series opener before a two-run first inning started things off on Saturday. The latter game featured a 12-hit performance, with four players posting multiple hits.

"We took (the Fenway Park crowd) out until the end and then they got a little rowdy like they do here, but overall, our guys continued to battle in another really good team victory," Twins manager Derek Shelton said.

Like Gray, Ober is in the midst of a solid run of his own. He has won back-to-back and three of his last four starts.

After holding the Miami Marlins to two hits in a complete-game shutout on May 12, Ober grinded through five innings of three-run ball to beat the Milwaukee Brewers in his most recent outing last Sunday.

"I'm not always going to have my stuff like I did last game, where I'm able to locate everything, and I know that," Ober said of his last outing. "I feel like I did enough for the team to stay in it."

Ober is 2-2 with a 2.48 ERA in five career starts against the Red Sox. He earned his second straight win in the series back on April 13, striking out seven through a six-inning start.
