SEATTLE — The anger and frustration on that day had reached a level not seen in the 2017 season. Baseball players, particularly at the big-league level, have a way of putting failure and losing behind them quickly and focusing on the next day’s game. It’s necessary for survival at the game’s highest level.

But in the immediacy after being shut out for second straight day at Fenway Park — something no other team had done in the organization’s history — Mariners players said little to each other as they dressed in a quick but sullen manner, as if getting away from the scene would somehow help them forget and move on.

Words likes “rock bottom” and “embarrassing” were used to describe what had transpired. The Mariners had sunk to their nadir on May 27. They were in last place in the American League West with a 21-29 record and threatening to have the worst record in the AL.

Eight days later, the feeling around the Mariners has changed. Following a crisp 7-1 victory over the Rays on Sunday — highlighted by Ariel Miranda’s complete game pitching effort — and three-game sweep of Tampa Bay, the mood around the Mariners has changed significantly. Music blared in the clubhouse postgame as players lingered, talked and laughed with an off day looming.

With the win, the Mariners have won seven of their last eight games to improve to 28-30 and into a tie for second place in a division race they likely can’t win. But a season teetering on the brink has been righted in a week.

“From where we were about seven or eight days ago to where we are right now, says a lot about our team and the makeup of the guys in that room,” manager Scott Servais said. “When things looked like they weren’t going so good, and they weren’t, I made the comment about being at rock bottom, I tip my hat to them. It’s about the players and they’ve stepped up.”

In the eight-game stretch culminating with that second shutout in Boston, the Mariners were 1-7 and averaging 1.1 runs with a .185 batting average, five doubles, a triple, three homers and nine RBIs.

Since then, they are 7-1 and averaging 7.1 runs with a .354 batting average with 20 doubles, a triple, 10 homers, 20 walks and 53 RBIs.

“Everything is starting to click,” said catcher Mike Zunino, who had two hits and drove in two runs. “We’re getting good performances on the mound and the lineup from top to bottom is producing. That’s when it’s fun.”

Miranda delivered the Mariners best outing of any starting pitcher this season and the team’s first complete game. He pushed through nine innings, allowing one run on four hits with a walk and nine strikeouts to improve to 6-2 on the season.

“Awesome job,” Servais said. “Miranda was on top of his game. It was really fun to watch. He was commanding the strike zone and was really aggressive with the fastball and enough off-speed pitches to keep them honest. He really wanted to finish that ballgame.”

Late in the game, Nelson Cruz approached pitching coach Mel Stottlemyre and relayed the sentiment that Miranda really wanted to try and finish the game. Always quiet and reserved, there was no way Miranda would make such an exhortation on his own.

“I think that’s great,” Servais said of Miranda’s desire to close it out.

When asked about it postgame, Miranda blushed and tried to downplay it.

“It just worked out for me,” he said through interpreter Fernando Alcala. “I wasn’t thinking about completing the game. I was just trying to focus on my work.”

Still all pitchers want that complete game if possible. Miranda carried a no-hitter into the fifth before a soft grounder to the right of the mound that he couldn’t make a play on resulted in an infield hit for Kevin Kiermaier.

It became obvious Miranda wanted the shutout. He probably should’ve had it. Daniel Robertson hit a high fly ball to center to start the eighth inning. Jarrod Dyson camped under the ball, but lost it in the sun on the way down. The ball struck Dyson in the shoulder and gave Robertson a triple. Miranda was able to get Brad Miller to pop out weakly for the first out of the inning. But Miranda’s former catcher — Jesus Sucre — ended the shutout bid with a ground ball to shortstop that allowed Robertson to score. Miranda pounded his glove in disappointment.

When the ninth inning rolled around, Miranda received a loud and partial standing ovation from what was left of the 28,579 in attendance as he jogged to the mound. He needed just seven pitches to close it out, getting three fly ball outs for his first complete game since 2010 in Cuba.

Miranda isn’t overpowering. He has deceptive 92-94 mph fastball that hitters struggle to pick up, a decent split-finger fastball and mediocre slider. But the Mariners love his ability to compete.

“He has no fear in attacking guys,” Zunino said. “That’s the biggest thing. When you do that, you aren’t afraid to throw to contact and it makes a world of difference. You wish all guys had his mentality to go right after guys. Even when his stuff isn’t as sharp like today, he’s still able to get outs.”
