MIAMI -- The good news for the Pirates was that they got terrific starting pitching in their four-game series against the Marlins.

In the end, however, their losing ways continued.

On Sunday afternoon at loanDepot park, Johan Oviedo went seven strong and surrendered just one run, but that was enough for Miami to pull out a 2-0 victory.

Although the Pirates snapped a 10-game losing streak on Friday night, they ended up losing three of four to the Marlins and have now lost 12 of 13 and 15 of their past 18.

Miami used four pitchers, including emerging star Eury Pérez (5-1), to hand Pittsburgh its 10th shutout loss of the season and fourth in its past nine games.

The Pirates had chances to win all four games against the Marlins -- and a lot of credit has to go to its starting pitching.

On Thursday, Pittsurgh took a 4-1 lead into the bottom of the eighth before the bullpen gave up five runs.

The Bucs rallied in the ninth for a 3-1 win on Friday, but they lost, 4-3, in 11 innings Saturday despite a solid start from Osvaldo Bido (two earned runs in 5 2/3 frames).

“There is frustration in that we could have won three of four,” manager Derek Shelton said. “You saw four well-pitched games from our starters. With the exception of one inning, we threw the ball well the entire series. We did a really good job. … It is an encouraging sign. Three kids are rookies, and one didn’t start big league camp with us. Right now, we’re getting elite starting pitching.’’

Sunday, Oviedo (3-8) gave up a home run to Jonathan Davis to lead off the third, and that proved to be all the offense the Marlins needed.

“He pitched his butt off,’’ Shelton said of Oviedo. “I mean, a 3-2 fastball to Jonathan Davis, threw a strike and he hit it. Other than that, he was in control. He controlled the zone, controlled his emotions, which I thought was challenging because he lives here and had a ton of family here. He went right after a very good team. He was outstanding.”

The Pirates mustered five hits, with just two coming in the final six innings and only Andrew McCutchen (2-for-4) getting multiple hits. Tucupita Marcano (1-for-1 with a walk) reached twice before being lifted for pinch-hitter Nick Gonzales in the seventh.

The Bucs left six on base and went 0-for-2 with runners in scoring position. They did not put a runner in scoring position after the second inning.

Not having Ke’Bryan Hayes available due to lower back stiffness did not help.

“It is a tough stretch, and that happens in baseball,” outfielder Connor Joe said. “The pitching staff is doing a great job, and unfortunately, we’re not picking them up with runs at this time.

“To be in all four of those games in this series despite lack of production from the offense is a positive. It’s something the team can build on. It gives us a chance. They’re picking us up right now, and we hope to produce for them.”

Oviedo, who was born in Havana, Cuba, and said he had over 25 friends and family in the stands, gave the Pirates enough to win.

“I always just try and give the team a chance to win the ballgame,” said Oviedo, who gave up the one run off six hits with six strikeouts.

“All I want to do is win, and as a team, we will get there. Just have to keep pitching hard each day. … I believe in this team and am not worried about what’s going on right now. I know we’ll get back.”

The Pirates had their best chance to score off Pérez in the second, when Henry Davis and Marcano advanced to second and third on a wild pitch with one out. But Rodolfo Castro and Austin Hedges were both caught looking for two of Pérez’s nine strikeouts.

“We have to put the ball in play when we have those situations,’’ Shelton said. “We have to execute, and we’re not doing that right now.”

Miami reliever A.J. Puk came on in the ninth and got three quick outs for his 11th save of the season as Pittsburgh went down in order in four of the final five innings.

All told, Pittsburgh scored a total of 10 runs against the Marlins in the four-game set, with three of those coming in the ninth inning of Friday night’s win and two coming in the eighth and ninth to force extras on Saturday.

“We have to figure out a way to score more runs,” said Shelton, whose team opens a six-game homestand against San Diego on Tuesday.

“I wish I had that answer. … We’re in a stretch right now where we’re not doing anything offensively, especially early in the game. That’s what we have to figure out.”
