PHILADELPHIA — From the on-deck circle, Kyle Schwarber had the best view of Trea Turner’s fight. He worked a 2-2 count with the bases loaded in the eighth inning Friday night. He fouled off four consecutive pitches, all of them strikes, and it felt like the at-bat was tilting toward Turner.“The momentum was there, right?” Schwarber said.Turner saw a splitter on the ninth pitch from Brent Headrick, and he scalded it … right at Cody Bellinger in left field. It was hit too hard. Bellinger was 271 feet from home plate and fired a rocket toward it. J.T. Realmuto retreated to third base. Two outs. Then Schwarber worked a six-pitch at-bat only to hit a harmless groundout. The Phillies lost 1-0 to the New York Yankees on a night when the visiting team had as many fans as the home side inside Citizens Bank Park.Even in a rare inning in which the Phillies had three men reach — single, hit batter, single — they could not score. It is increasingly hard for this team to score runs without hitting the ball over the wall. That is something the Phillies can do; they are tied for fifth in the majors in home runs. It’s the easiest way to score. It is a strong blueprint for October.But until something drastic happens, this team will be defined by its on-base percentage — now .302, the worst mark in Major League Baseball. It’s a 26-point drop from a season ago. Only the Toronto Blue Jays have suffered a larger year-over-year decline.How many players will the Mets trade by the deadline?Ken Rosenthal and Johnny SweetIt is difficult to win when you make an out 70 percent of the time. The Phillies are 2-5 since the All-Star break with a .278 OBP in those games. They’ve lost three games in the standings to the Atlanta Braves during that stretch. On Friday, the Phillies faced a young righty, Cam Schlittler, who might win the American League Cy Young Award. He carved through them.“I don’t feel like there’s anything more troubling to read into it,” Phillies interim manager Don Mattingly said. “We’re playing some good clubs. We’ve run into some guys that throw the ball well. But again, I just think we’re in a little bit of a lull right now. It’s part of the season. Don’t want to read too much into it.”And this is where the Phillies will lose some folks. They sold out Friday night because of the Yankees fans, but they did not sell out the games earlier this week against the Los Angeles Dodgers, and the average attendance (39,493) at Citizens Bank Park is down a bit from a season ago. It’s more expensive to come to a game now. But it’s easier to be apathetic about a team that looks and acts the same as it has while falling short in previous years.This is the trap the Phillies have to prevent themselves from entering because it is not hard for the mood in the seats to permeate the clubhouse. They’ll make upgrades at the trade deadline, but there is no one offensive move that is going to change the entire dynamic of this lineup.“The biggest thing is knowing we’re putting ourselves in situations to win the games, right?” Schwarber said. “The overall number might not look like what you want it to be. Sure, you want a higher on-base percentage, absolutely, as a team. But, also, we put ourselves in spots like today. We put ourselves in that situation.”It feels like something wasted whenever the Phillies lose a game started by Cristopher Sánchez, Zack Wheeler or Jesús Luzardo. Friday, they were gifted seven strong innings from Luzardo, who allowed only one run, on a pitch that wasn’t even a mistake. He has a 1.46 ERA in his last eight starts. The Phillies lost a Luzardo start for the first time since May 19.“Any loss is a little frustrating for anyone in this clubhouse, especially knowing how we clawed back from where we were early in the year,” Luzardo said. “But I think there’s a little sense of, you know, we’re right there. We’re not getting blown out.”They are going to use a 32-year-old righty named Brian Keller in Saturday’s game. He could start or pitch in bulk relief. Keller, who was a 39th-round pick of the Yankees in the 2016 amateur draft, when there still was a 39th round, had not pitched in affiliated ball since 2022 when the Phillies signed him in May.They are desperate. So they will see what Keller, who threw strikes in eight starts at Triple-A Lehigh Valley, has to offer.He will replace rookie reliever Alex McFarlane on the roster.If it seems like the Phillies are biding time until the Aug. 3 trade deadline, maybe they are. The front office continues to debate which need is most pressing. There is a good argument for another bat, whether it’s right- or left-handed, but there is a counterargument that a solid-enough upgrade won’t appear in a barren market.Schwarber, who only has five homers in 27 games since his three-homer game June 20, has cooled down. Bryce Harper is in a rut. Brandon Marsh has regressed to the mean. Trea Turner is hitting again. Bryson Stott and Alec Bohm have been fine, mostly. But without enough hitters in the lineup who reach base at an acceptable rate, opponents can navigate around the trouble spots with ease.Schwarber wants his teammates to think like this: Stay in the fight. The Phillies have played with a lead in previous summers, and it didn’t matter in October. Even if they were winning now, they would still have to prove it in October.The reality is no one is probably going to feel great about this team until the randomness of the postseason — provided the Phillies get there — and definitely no one is going to feel great in October because it’s inherently stress-inducing. It makes this whole thing a little frustrating.At least they had a chance in that eighth inning.“You kind of sit back and laugh after getting in that spot,” Schwarber said. “It’s like, man, we feel like we had the quality at-bats to get the job done. And baseball just had a different plan.”
