​NEW YORK – Soaring past career highs in starts and innings pitched, Ryan Weathers is also enjoying his finest stretch as a Yankees starter.That workload is at least something to be mindful of, as we reach the stretch drive.Carlos Rodon is scheduled to go Thursday at Class AA Somerset, in what might be his final rehab start, coming back from elbow inflammation.If the Yanks have five healthy starters, plus Rodon coming back, either Weathers or Will Warren will be moving into the bullpen.“We haven’t really addressed it with the group yet,’’ said pitching coach Matt Blake at the Stadium, after Weathers boosted the Yankees to a 4-1 win Tuesday night against the Mariners.“Obviously, the natural guys to talk about are Ryan and Will and we haven’t really gotten to that, as far as who it would be or when it would happen.’’And lately, Weathers has made a strong case to remain in rotation.Suddenly, a crowd of starters The lefty’s consecutive scoreless innings streak, over three starts, was snapped at 22.2 innings by Randy Arozarena’s short-porch homer in Tuesday’s sixth.To that point, the Yankees’ lineup – struggling mightily since mid-June – had no answers versus Seattle starter Bryan Woo.But against Seattle’s bullpen, the Yankees strung together some professional, patient at-bats, batting around and taking a 4-1 lead on two-run singles by Ryan McMahon and Trent Grisham.“Wish I could’ve thrown a few more strikes,’’ said Weathers, who exited after 5.2 innings, with his pitch count at 106 and took a no-decision.Over the last two years, Warren has been more durable than Weathers, who has previous bullpen experience with the Miami Marlins.If the Yanks bring Rodon back after Thursday, he’s likely going to start with a roughly 65-pitch limit – inviting the possibility of a tandem start with Warren or Weathers.In a four-man postseason rotation, have a signature strength with Cam Schlittler, Gerrit Cole, Max Fried and presumably Rodon in some order. Meanwhile, Clarke Schmidt’s return to the Yanks (Tommy John surgery rehab) might be delayed until September, due to a recent forearm cramp.At Class A Hudson Valley, Tuesday, Luis Gil tossed his scheduled one inning (scoreless) and he’s at least a potential late-season bullpen option as he recovers from shoulder inflammation.Acknowledging a lack of big-league ready Yankees starting depth at Triple-A, “you’ve got to know where the balance is’’ of transitioning Weathers or Warren into relief, said Blake, versus “keeping him built up in case something happens.’’Ideas for moving Weathers or Warren to reliefThe idea of optioning Weathers or Warren to the minors, to transition into relief, hasn’t been discussed, “but it’s in the universe of things that could happen,’’ said Blake. “I wouldn’t say we’re at that point.De-escalating a starter is “probably harder’’ at the big-league level, said Blake, though the extra pitcher during September’s ros
