Electrical issues near Miami’s Loan Depot Park led to communications outages between umpires and the MLB replay headquarters and intermittent television coverage of the series finale between the Cardinals and Marlins on Wednesday.

Unfortunately for the Cardinals, the power outage also spread to their lineup that was resting several regular starters in a lackluster 4-1 loss to the Marlins in Miami.

About to begin a stretch where they will play 17 games in 17 days, Cardinals’ manager Oliver Marmol made the decision to rest sluggers Alec Burleson and Jordan Walker and standout shortstop Masyn Winn on Wednesday. That clearly played a role in the punch the Cardinals were able to deliver and they were ultimately shut out over the game’s first eight innings before a solo shot by Ivan Herrera in the ninth.

The loss cost the Cardinals a chance to win another series and it left them 4-2 on the two-city trip to Houston and Miami. Following a day off on Thursday, the Cards will host a three-game series against the Mariners – minus injured All-Star infielder Brendan Donovan – beginning on Friday night.

Here are three takeaways from Wednesday’s game in Miami:

Kyle Leahy, who had the best success of his MLB career in a relief role in 2025, has said repeatedly that he is still working to transition into a starting role. Figuring out the pacing of work on his days between starts, Leahy said, is still a work in progress.

Leahy never looked comfortable over his five innings of work on Wednesday. He allowed eight hits and four earned runs, while walking three and striking out two. Leahy threw 89 pitches, but just 50 of them for strikes.

The Marlins reached Leahy for two runs in the second inning. Liam Hicks and Agustin Ramirez opened the inning with singles, and Ramirez came around to score when Owen Caisse slapped an opposite-field single. Miami made it 2-0 when Leahy threw four straight balls after getting ahead of Jakob Marsee, forcing in a bases loaded run.

The Marlins added solo runs in the fourth and fifth innings to take a 4-0 and knock Leahy out of the game.

Coming off a solid rookie season where his sinker proved to be a devastating out pitch, Matt Svanson was thought to be a key piece of the Cardinals bullpen this season. However, he’s mostly struggled with his command and has been hit hard early this season.

On Wednesday, he delivered a much-needed 1-2-3 seventh inning of work with a strikeout.

Svanson’s outing on Wednesday lowered his ERA to 11.08 over 11 outings. He’ll need several more flawless outings like Wednesday’s to get his ERA more in line with his career mark of 3.56 at the MLB level,

Herrera, who is widely considered to be one of the Cardinals most complete hitters, hasn’t had the start of the season that he wanted as pitchers have mostly taken the bat out of his hands and made others beat them.

Herrera came into Wednesday with 18 walks, good for second in the National League to Washington slugger James Wood (21 walks). Showing patience and not chasing speaks to Herrera’s growing maturity as a hitter, but it has led to some frustration for him.

Herrera did get a fastball he could handle in Wednesday’s ninth inning, and he drove it 388 feet – and 108.2 mph off the bat – for his third homer of the season. Herrera’s first homer of the season didn’t come until the 17th game of the season, but Wednesday’s smash was his second in six games.
