“You come out 13-2 and everybody’s like, ‘Oh my gosh, this is the greatest thing ever,’” Manager Scott Servais said. “We were going to regress a little bit. It’s fun, but it’s baseball. When it’s all said and done, we’ll be fine. The whole goal of the season was to just continue to get better.”

By that, he means the health of the organization, not necessarily the major league record. Predictably, the Mariners have slumped since their hot start, falling to 20-19 over all after losing two of their first three games at Yankee Stadium this week.

They won, 10-1, on Wednesday with three home runs that pushed their major-league lead to 74, but they also lead the majors in errors by a wide margin, with 41.

“We are a team that has been full of extremes so far,” right fielder Jay Bruce said. “I’m looking forward to seeing how it plays out.”

For Bruce, who has a .188 average but 11 homers, it could play out as it has twice before — with a midseason trade to a contender. The Mets acquired him in 2016, traded him in 2017, then re-signed him and dealt him to Seattle in a deal for Robinson Cano and Edwin Diaz in November.

The prospects the Mets gave up in that deal — outfielder Jarred Kelenic and starter Justin Dunn — have thrived in the minors this season. So has shortstop J.P. Crawford, a faded prospect for Philadelphia who arrived in a trade for shortstop Jean Segura and may soon be called up to Seattle.
