ANAHEIM, Calif. — A loss like the one the Yankees suffered on Sunday had the feeling of a game that could come with lingering effects.

But in the immediate aftermath, the Yankees insisted they would not let that be the case, and they set out on Monday to try to prove it.

“Morale is fine,” manager Aaron Boone said Sunday after the crushing 8-7, 11-inning loss to the Rockies at Coors Field. “Look, it’s on us. We know what’s in front of us. We know the expectations on us. We can talk about it. Everyone, I know, is going to talk about it. We gotta go do it.

“We’ve got the canvas in front of us to write our own script. That’s what we’re working hard to do.”

So far, the Yankees have veered well off-script from the one they envisioned in spring training.

Entering Monday’s game against the Angels, they sat in a last-place tie with the Red Sox in the basement of the AL East, 94 games into the season.

The Yankees were also two games out of the final wild-card spot, and while the expanded playoff format gives them a little more margin for error, their runway to get going is shrinking by the day.

“I just don’t think there’s time to be in disbelief,” said Anthony Rizzo, whose extended slump and power outage at the plate has been part of the Yankees’ larger lineup struggles. “You just gotta keep grinding, just play better baseball all around. Offensively, we gotta grind together.”

The Yankees have not won three straight games since winning four in a row from May 27-30.

Since then — a span that coincides with Aaron Judge landing on the injured list after tearing a ligament in his big right toe on June 3 — the Yankees have won back-to-back games five times but have not been able to turn that into a full-fledged hot streak.

“I wish I knew,” Rizzo said when asked to explain the Yankees’ inconsistency. “It’s frustrating on all ends. The guys who have been in here and done it for a long time, we’re equally as frustrated. But we know that’s not going to do anything for us.”

At some point in the next few weeks, the Yankees hope to get Judge back in their lineup — though it remains to be seen how effective he will be while likely still having to play through some discomfort.

The trade deadline could also help, depending on what deals general manager Brian Cashman is able to pull off.

But the Yankees can’t just wait around on those two factors, either, to start playing better.

“We know we need to string together some good baseball and put some wins together,” said Clay Holmes, who gave up a grand slam in the eighth inning Sunday to blow a two-run lead. “We believe that we’re capable. It’s not like there’s not that belief. But at the same time, we understand that it needs to happen. One way or another, we gotta start figuring it out.”

A more productive offense would go a long way in making that happen.

The Yankees had a prime chance to break out over the weekend in hitting-friendly Coors Field, where they faced three starting pitchers each with an ERA north of six and a bullpen that entered the series with the fourth-highest ERA in the majors.

Instead they dropped two of three, with Sunday’s disaster marking the first time in franchise history in which the Yankees lost despite having multiple leads of at least two runs in the eighth inning or later, per the Elias Sports Bureau.

“This is part of it,” Rizzo said. “I know the division looks like that and I’m sure the headlines will be ‘last place’ or whatever. But we’re not far off from the wild card and we’re not far off from being in second place in this division. Then again, we’re also not far off from being in last place and out of it.

“So it’s not an ideal situation you want to be in, but at this time of the year, it doesn’t matter what position you’re in. It’s about getting into the playoffs.”
