PHILADELPHIA — After Mets right fielder Michael Conforto had beaten out an infield single, stolen a base and homered Wednesday afternoon, he stood at his locker and wore a gray T-shirt emblazoned with “Pressure is a privilege.”

The Mets had lost for a second straight day, this time by 3-2. Conforto’s final at-bat, which came in the ninth inning, ended with a shot that was caught a few feet short of the right-field fence. Despite all he’d done, including homering for a second straight game, he lamented his inability to finish the job.

“We didn’t do enough when we were here,” he said as the team readied to fly to St. Louis for a weekend series. “All aspects of the game are important: defense, base running, pitching, hitting. When you’re playing teams that are as good as we have in the division, we have to put the whole thing together.”

Conforto, 26, has been the full package thus far. As the lone Met to appear in the starting lineup every day this season, he has reached base in 13 of the last 14 games, a stretch in which he had 12 extra base hits, 12 R.B.I. and 13 runs scored.
