MIAMI -- Marlins manager Don Mattingly might have decades in baseball, but a ninth-inning sequence that nearly ended Wednesday night’s game has never been a regular occurrence.

“There's been some stuff going on lately that I haven't seen before, but that's what they say about this game, right?” Mattingly remarked. “You see something every day that you've never seen before.” 

There was plenty of that in Miami’s 5-4 loss in 10 innings to Washington at loanDepot park.

Trailing 4-3, the Marlins loaded the bases on a Jesús Sánchez single and consecutive one-out walks by Miguel Rojas and Erik González. Jazz Chisholm Jr. then sent Tanner Rainey’s first-pitch slider 277 feet into right field. Sánchez tagged up and ran home, beating Juan Soto’s 84.2 mph throw. But third-base umpire Chris Guccione said Sánchez (28.3 ft./sec sprint speed) left the bag early, and the Nationals began their victory handshake line.

The Marlins asked for a replay review, and both teams spent several minutes in limbo. Sánchez nervously stood in the dugout awaiting the decision from New York.

“I was a little nervous in that situation, but I knew I had executed the play correctly,” Sánchez said via an interpreter.

Chisholm sat in foul territory not too far from first base. 

“You're upset,” Chisholm said. “You're going to be upset because you want to win every night. You don't want to go out [there] and lose, especially off a play like that.”

Nationals catcher Keibert Ruiz, who received Soto’s throw on the play, wasn’t sure.

“[Third baseman Maikel] Franco said, 'Yes [he went early],'” Ruiz said. “[We were] just waiting for the replay review.”

Eventually, the call was overturned, helping send the game to the 10th. It was Miami’s first extra-inning game since Opening Day on April 8 in San Francisco.

“I was hoping that it would go our way, and it's rare to see a guy leave that early,” Mattingly explained. “It wasn't like one of those that you had to really cheat too much. You felt pretty confident that it was deep enough. I wasn't totally confident, but I was optimistic.” 

That ninth-inning play wasn’t the only oddity from the series finale.

Chisholm might’ve been feeling under the weather all day, but you wouldn’t have been able to tell by his performance. He reached base a season-high-tying four times and also tallied two of the five furthest-hit balls on the night.

When César Hernández opened the game with a triple, Chisholm responded with one of his own in the bottom half of the frame. It marked the 19th time since 1916 that both clubs tallied a leadoff triple, and the first since Aug. 5, 2005, by the Twins’ Lew Ford and the Red Sox's Johnny Damon. Chisholm reached a sprint speed of 30.1 ft./sec. on the play, just a touch above the "elite" threshold (30 ft./sec.).

After his game-tying solo homer to right-center off Josiah Gray in the fifth inning, the home broadcast showed Chisholm returning to the dugout and grabbing a hot beverage, then covering himself with a towel. He was a more subdued version of his usually energetic self.

“‘I could get out there and play anytime you need me, I'll push through it,’” Chisholm had told the club when he arrived at the ballpark. “I went out there and I did it. I just had to stay focused when it was time to get focused -- turn the switch on when it was time to.”

And while pitchers aren’t batting anymore (unless you’re Shohei Ohtani or Albert Pujols), Mattingly replaced the extra-innings automatic runner Jesús Aguilar (24.2 ft./sec.) with reliever Anthony Bass. Miami was fielding a short bench with Jorge Soler, who is dealing with lower back stiffness, and backup catcher Payton Henry (26.2 ft./sec.) remaining.

The last time the Marlins used a pitcher in a pinch-running situation was reliever John Curtiss last July 22, in a loss to the Padres.

Though Bass was unable to advance on Garrett Cooper’s groundout to the left side of the infield, he reached third on Avisaíl García’s flyout to center with a 26.1 ft./sec. sprint speed (27 is league average).

“That's pretty much spontaneous,” Mattingly said. “I'm like, ‘[Pitching coach Mel Stottlemyre Jr.], we got anybody that can run out there?’ Because I'm looking at Agui at second, the inning before I knew he made the last out. Kind of like the same [Nelson Cruz] on their side and they’ve got Dee Strange-Gordon, and I didn't really have anybody. He actually did a nice job tagging. Good read on that ball to center, slid [and] didn't get hurt.”
