PHOENIX – Nobody worried inside the Phillies’ clubhouse.

The club played its worst two games under interim manager Rob Thomson on Monday and Tuesday, getting clobbered by the D-backs at Chase Field. It blew a seven-run lead on Monday and allowed 25 runs overall. After each loss, Thomson calmly and coolly reminded people that it was only one game, even as Phillies fans back home had flashbacks of late-season collapses from the recent past.

But the Phillies snapped a three-game losing streak Wednesday night with an 18-2 pummeling of Arizona. The victory maintained a half-game lead over San Diego for the second NL Wild Card and a three-game lead over Milwaukee, which is chasing both teams.

“I’ve been in many of those kinds of losses before,” Phillies left fielder Kyle Schwarber said. “They happen. You don’t want them to happen, but they happen. You can’t worry about it. If you go out there and think about it, what are you going to do well? You’ve got to focus on what’s ahead of you today. Does it stink in the moment? Absolutely. But you have to keep things in perspective. There’s nothing we could do about them after they were over. We came together today and were ready to play. We did our thing.”

Everybody hit. It was the first time each starter in the Phillies’ lineup had at least two hits in a game since 1901. It was only the 35th time it happened in baseball in the past 121 years.

The Phillies scored their most runs in a game since they scored 20 against the Marlins on April 7, 2018. The game also marked the first time the Phillies have scored 18 or more runs without a homer since Aug. 17, 1941, in the second game of a doubleheader vs. the Giants.

They were 15-for-29 with runners in scoring position. It was their most hits with runners in scoring position since they had 15 in a 26-7 victory over the Mets on June 11, 1985, at Veterans Stadium. It tied for the most hits with runners in scoring position in a game by any team this season.

“And Bailey did an unbelievable job,” Schwarber said.

Phillies left-hander Bailey Falter allowed one run and five hits in 6 1/3 innings. He struck out six. It was the best start of his career, but it ended with him walking off the field with assistant athletic trainer Aaron Hoback. Falter experienced tightness in his right groin.

He received treatment immediately and said he felt “100 percent better” than when he left the field.

Falter is 3-3 with a 4.08 ERA this season, which is no small beat considering he has been up and down from Triple-A Lehigh Valley seven times. But lately, Falter has really come on. He is 3-0 with a 2.59 ERA in his last four starts. The Phillies won each one.

It started July 29 in Pittsburgh. It was Falter’s last start as Zach Eflin’s replacement before the team acquired Noah Syndergaard on Aug. 2. Falter allowed two runs in six innings in a 4-2 victory. Falter got called up on Aug. 20 to pitch Game 2 of a doubleheader against the Mets. He allowed one run in six innings in a 4-1 victory. It was the only game the Phillies won in the four-game series. Falter got called up again Friday against the Pirates at Citizens Bank Park. Zack Wheeler had just been placed on the 15-day injured list. Falter allowed three runs in six innings in a 7-4 victory.

Then Falter helped the Phillies avoid a sweep in Arizona.

“You have to adapt if you want to stick around in this game,” he said. “I’ve got a job to do. You’ve got to roll with the punches sometimes. It’s not always going to be fair, but it’s a business. That’s all it is.”

Wheeler could be back in the rotation Tuesday, which could make Falter’s situation unclear again.

“He’s stretched out now,” Thomson said. “Theoretically, you could keep him for a while and then if you need to stretch him back out you do that. We haven’t talked about it. We need to get Wheels back first.”

If for some reason Wheeler is not ready, Falter will be ready.

“It’s the nature of the game, but the way he’s handled it, he’s always been the same guy with the same personality, ready to make a start,” Schwarber said. “He expects to go deep. He did tonight. It’s huge for us.”
