WASHINGTON -- Trea Turner thought he had it.

He has barreled enough baseballs in his life to know what it feels like when he hits a home run. He loved how it felt when he crushed an 0-1 fastball to deep left field to lead off the ninth inning in Sunday’s 3-2 loss to the Nationals at Nationals Park.

“I thought it was 100% a homer,” Turner said.

So it surprised him to see Nats left fielder Jesse Winker in pursuit.

“I was like, 'Why is he jumping for the ball?'” Turner said. “Honestly, I hit the ball the same as J.T. [Realmuto’s] homer yesterday. The numbers were there; I felt like I hit it. I felt like I put a good swing on it. I hit it right down the line -- it’s not too far there -- so I thought, for sure, it was getting out.”

Realmuto hit a three-run home run to left-center field in Saturday's 5-2 win. The ball had a 105.8 mph exit velocity and a 22-degree launch angle, according to Statcast. Turner hit his ball at 106 mph with a 23-degree launch angle. Baseballs hit with those metrics result in a hit 88% of the time. It also would have been a home run in 12 ballparks -- including Philadelphia's Citizens Bank Park -- per Statcast.

Instead, Winker made a leaping catch at the wall to take away an extra-base hit.

The Phillies had a chance to sweep the Nationals on Sunday and move over .500 for the first time this season. Instead, they head to St. Louis for a three-game series sitting at 4-5.

The Phils lost, in part, because they managed only five hits against the Nationals. The top six hitters were a combined 2-for-20 with three walks and six strikeouts. Phillies manager Rob Thomson started Whit Merrifield in left and Edmundo Sosa at second against left-handed starter MacKenzie Gore. They were the only reasons the Phillies had a chance to tie in the ninth.

Merrifield singled, stole second and scored on Sosa’s two-out single to left in the second to give the Phillies a 1-0 lead. Sosa then hit a solo homer to left in the fifth to tie the game at 2.

But teams can still win games when the top hitters aren’t hitting. They just need to do the little things well.

The Phillies, though, made two outs on the bases. Kyle Schwarber got doubled up at first on a flyout to center field to end the third.

“A totally bad read on my part,” he said. “I wanted to get to third base there. By the time I realized it was going to get caught, I was just way too far off the base there. That’s got to get cleaned up by me.”

Schwarber was also caught stealing to end the fifth, going on the first move from Gore -- but Nats catcher Riley Adams made a good throw. The Phillies have been caught stealing six times this season. They have made six other outs on the bases. Both of those numbers are the most in the Majors.

“We all know that we have to improve our baserunning,” Schwarber said. “We know it hasn’t been where we want it to be. But we want to keep the aggressive thought in our head, because we want to take the extra 90 feet whenever we can. That puts us in a good position. For me, in all reality, that ball in the [third], I probably end up at second base anyway, not third. We’re going to learn from the mistakes, while keeping the aggressive mindset.”

Turner added: “Right now, I feel like we’re a little out of sorts there."

Thomson said he recalls the Phillies running into too many outs early last season, too. It improved in time.

“A lot of times it’s tough to talk about it because then everybody stops being aggressive,” Thomson said. “There’s a balance that you’ve got to strike.”

Meanwhile, the Nationals stole five bases, which contributed to two of their runs. The Phillies have allowed 13 stolen bases this season, the second most in MLB at the time Sunday’s game ended. Realmuto has been behind the plate for two five-stolen base games this season.

He had never allowed more than four in a game before.

The Phillies allowed too many stolen bases late last season, which they worked to improve entering the postseason.

Is it something that needs to be re-emphasized again?

“We focused on it in Spring Training," Thomson said, "but we’ve got to be better at it."
