In fact, Sale already accomplished the feat once before from May 23 to June 30, 2015 when he registered eight straight starts with 10 more or strikeouts.
"Just finding a good rhythm and tempo", Sale said.
Morrison, who went deep with one out in the second, said he chose to guess changeup and got one, extending his sizzling start with his team-leading 10th homer. "That's the key to pitching, going out there and trying to get in a groove".
Kevin Kiermaier and Logan Morrison homered for Tampa Bay, which has dropped seven of 11.
It looked like a good pitch, a 2-2 96-mph fastball down and in to Derek Norris.
Joe Kelly worked the eighth before Craig Kimbrel finished the three-hitter for his 11th save. It was Betts' fifth homer of the season and third in his last four games, and helped Boston salvage one win in the three-game series in the Red Sox's first trip to Milwaukee since 2003.
"Obviously today we saw a lot of power", Tampa Bay manager Kevin Cash said. The Rays fanned 16 times. "The first six or seven innings they've got the best lefty in the American League throwing". "Chris for every adjective we've given so far - a lot of swing-and-miss, competitive, quick-paced, deep into games - it's a blueprint of the other six starts as I mentioned".
Rays: LHP Blake Snell (0-3, 3.96 ERA) hopes to rebound from a rough outing Monday against Kansas City when he gave up a career-high 10 hits in a loss. Robert Gsellman (2-3) was charged with six runs, five earned, and nine hits in four-plus innings.
Nationals 6, Phillies 4 • Bryce Harper hit a walk-off home run with two outs in the ninth inning that sent Washington past Philadelphia.
Red Sox: Hanley Ramirez received treatment in the morning for a muscle spasm in his right upper back that forced him to leave the game Wednesday. Betts followed with his RBI double, and Xander Bogaerts added a run-scoring grounder.
According to oddsmakers from online sports book BetDSI, the Red Sox are -245 money line favorites versus the Rays, who have odds of +215 to pull off the upset in Boston.
That was all Sale needed.
Rays: Cash expects OF Steven Souza Jr. RHP Tommy Hunter, on the 10-day disabled list with a strained right calf, threw a bullpen session and felt fine.
Saturday's game, which was scheduled for a 7:05 start, was moved to 1:05 with the forecast for heavy rain starting later in the day and into Sunday. He posted eight twice, his last coming in the final starts of his AL Cy Young Award-winning 1999 season.
Brewers 11, Mets 4 • Travis Shaw capped Milwaukee's eight-run fifth inning with a three-run homer, helping the host Brewers beat NY.
The Rays are 5-12 in their last 17 road games versus a left-handed starter, and 1-4 in their last five games versus a left-handed starter.
Reigning AL Cy Young Award victor Rick Porcello (2-5) gave up five runs - three earned - with seven strikeouts in six innings for his second rough outing against the Rays this season.
Snell debuted on the Tampa Bay roster last season, making 19 starts down the stretch for the Rays, posting a 6-8 record with a 3.54 ERA, posting a 9.9 K/9 rate.
