The Phillies believed they would score seven runs to overcome a six-run deficit on Thursday to beat the Nationals, and they did.

Positive thinking worked that afternoon.

It could not power the Phillies to another comeback victory on Friday night against the Marlins at loanDepot park. They allowed seven runs in an ugly sixth inning to send them to a 10-3 loss. It snapped the Phillies’ six-game winning streak. It snapped their seven-game streak of seven or more runs scored. But, most importantly, it prevented the Phillies (69-65) from gaining ground on the Braves (71-63) in the National League East and the Reds (72-64) for the second NL Wild Card. Instead of being a game behind both teams in both races, they remain two behind with 28 to play.

“We need to start a streak again,” Phillies manager Joe Girardi said. “It’s important because we need to win games. There aren’t that many left.”

Winning streaks have been hard to come by in Miami for the Phillies over the past several years. They are 11-19 at loanDepot park since the beginning of the 2018 season. They have not won consecutive games in a series in Miami since 2017.

The Phillies played a rare seven-game series in Miami last September. They entered 1 1/2 games behind Atlanta and in second place in the division. They lost five of seven. They left town four games behind Atlanta and in third place.

But the ballpark or the team isn’t on the minds of the Phillies as they play this weekend. Some of the players the Phils acquired at the Trade Deadline said they haven’t heard anything about the team’s recent problems in Miami.

“No, I haven’t heard anything,” Freddy Galvis said. “You’re just telling me. Just try to turn the page and get ready for tomorrow. We’re playing really good baseball the last few weeks.”

“Nobody said anything coming into the series,” Kyle Gibson said. “It’s crazy, some teams and some matchups just end up that way. I know with Minnesota when we were not too good, Cleveland never wanted to play us. Every now and then that happens and you run into a team, whether it’s just a matchup or when they’re at home or whatever it is, but we’re still really confident. We’re excited to come back tomorrow and get it going the right way again.”

The Phillies will need to play better than they played Friday.

Galvis hit the first leadoff homer of his career to open the game, but Marlins right fielder Jesús Sánchez answered with a three-run homer against Gibson in the first to make it 3-1.

Matt Vierling’s triple with no outs in the second scored Andrew McCutchen to cut the deficit to one, although the Phillies could not score Vierling from third. Vierling came through again in the sixth, dropping a double down the left-field line to plate the tying run.

But then disaster struck.

It is difficult to sum up everything that happened to the Phillies in the sixth. But know this: seven runs scored and 12 Marlins batted. Jazz Chisholm Jr. hit a leadoff triple. The throw to third beat him to the bag, but Galvis could not handle the throw. Galvis then had a rare throwing error to second to open up the inning. Gibson, who allowed eight runs in 5 1/3 innings, hung a breaking ball to Jorge Alfaro to keep the inning rolling. JD Hammer walked a batter with the bases loaded to surrender a run. He allowed another run to score on a wild pitch.

“It’s baseball, man,” Galvis said. “We’ve been playing really good baseball. Today it was just one inning.”

The Phillies will turn to left-hander Ranger Suárez on Saturday. He has a 2.03 ERA in six starts this season.

Maybe he can reverse the Phillies’ fortunes in Miami.

“He’s a really good guy for tomorrow,” Galvis said.
