Now , where were we?

The dizzying inaugural London Series felt more like a month than a weekend, albeit a fun month. The only baseball conclusion to draw from the Yankees’ overseas beatdown of the Red Sox? Boston’s bullpen, suspected as a liability ever since Craig Kimbrel’s departure last offseason, appears more cooked than the roast Principal Skinner made for Superintendent Chalmers in “The Simpsons.”

Throw in the fact that the Yankees entered the rivalry event on a 9-1 run, with their overall stretch of winning 13 of 14 putting them comfortably ahead of both the Rays (seven games entering Tampa Bay’s game Monday night) and the Bosox (11 games) in the American League East, and you can lose yourself in the glee of the moment.

To sober up, look at the calendar: July 1. Bobby Bonilla Day. Less than a month before the trade deadline. Work remains for the Yankees, just as much off the field as on it. How that work should get accomplished remains largely in question.

“I’d love to add pitching if I can,” Brian Cashman said Sunday at London Stadium, before his team slugged past the Sawx again. “Whether it’s bullpen, rotation. Just reinforce our pitching, and get our pitching that’s hurt healthy, and then have the pitching we currently have stay healthy.”

Sure, that would do the trick. Domingo German, quite effective until a left hip flexor strain impacted his work and ultimately landed him on the injured list, hopes to return to the starting rotation this week, which would take the Yankees’ largely successful opener deployment out of the mix and consequently strengthen the bullpen.

Luis Severino, on the other hand, leads the Yankees in just one category — setbacks — this season. On the bullpen front, this week could be a big one for Dellin Betances, who like Severino has missed the entire campaign. J.A. Happ and James Paxton, meanwhile, must improve their performances in addition to avoiding the IL.

Naturally, the external reinforcements intrigue us more, and the march of the schedule has seemingly eliminated some targets — the Nationals’ impressive climb back into the race means they can’t possibly trade Max Scherzer, and Mike Minor has helped make the Rangers too much of a bona fide contender to get jettisoned — while underlining others.

The rebuilding Giants must deal walk-year veterans Madison Bumgarner (who can block a trade to the Yankees) and Will Smith. The Blue Jays figure to sell high on Marcus Stroman, although clubs will want to see him pitch some after he left his start Saturday with what was called a “left shoulder pectoral cramp.” He’s scheduled to start Thursday night against the Red Sox.

The Indians stand as the most intriguing entity. Very much in the heart of the AL wild-card race yet well behind the Twins (eight games) in the AL Central, would they trade starter Trevor Bauer and/or reliever Brad Hand, each under team control through next year, and try to execute the same “Rebuild and contend simultaneously” trick as the 2016 Yankees?

Would Bauer’s entertaining love of Twitter battles (not to mention drones) concern the Yankees at all?

Another likely available piece, the Mets’ Zack Wheeler, will take on the Yankees Tuesday night at Citi Field as the Subway Series resumes. Would the Mets actually send Wheeler across town, with the fear that he could regain last year’s peak form and win a ring with the Yankees? It remains hard to believe.

You can bet heavily that all of these possibilities and many more have occupied the Yankees’ time.

“I’ve got nothing to show for my efforts,” Cashman said Sunday, and he emphasized that he treated his time in Europe no differently, texting his fellow general managers with trade proposals as he would if he were back in New York.

Back to North America, back to reality. Entering play Monday, the Yankees starters’ 6.4 wins above replacement, as per FanGraphs, tied them for eighth (with the Tigers) in the AL and put them behind the other seven AL teams with winning records.

The London trip heightened what has been a special season already. Can you envision it finishing as special without some more outside assistance, though? You’re far from alone in your pessimism.
