It has been a week since the Trade Deadline. Aside from the players rehabbing their way back from injury, the Marlins' roster is more or less what it'll be for the remainder of the season.

With 54 games remaining, here are three storylines to follow:

First taste of Majors

Outfield prospects JJ Bleday (No. 5) and Peyton Burdick (No. 10), as well as infielder Charles Leblanc are starting on a daily basis for Miami, which is without Jorge Soler, Avisaíl García, Brian Anderson and Jon Berti for the time being. Both Bleday (11-for-52) and Burdick (2-for-9) were selected in the 2019 MLB Draft, while Leblanc (12-for-27) was a 2021 Rule 5 Minor League Draft pick.

"We want to get to see JJ, want to get to see Peyton," manager Don Mattingly said. "I’m not necessarily playing an all-kid lineup or anything like that. But to get these guys at-bats to see what we've got, so the organization can look at them, help them make decisions going into the winter. I think just play with an energy, because we’re going to get [Jon] Berti back. We’re going to get [Brian] Anderson. I’d like to be able to mix this group together, where you’re not playing all kids."

Welcome back?

When the Marlins selected the contract of Burdick, they optioned Jesús Sánchez to Triple-A Jacksonville. The 24-year-old got off to a strong start in April (.839 OPS) before failing to make adjustments over the next three months (.601 OPS). Can Sánchez improve his approach at the plate to return to The Show in 2022?

Left-hander Trevor Rogers begins a rehab assignment with Double-A Pensacola on Tuesday. Last year's National League Rookie of the Year runner-up hasn't come close to that type of production in 2022, compiling a 5.85 ERA in 19 starts prior to experiencing back spasms. Will the Rogers of old rediscover his mechanics and return? Jesús Luzardo, Edward Cabrera and Braxton Garrett have been impressive their last turn through the rotation.

Breaking it down

For the second straight summer, the Marlins kept both Garrett Cooper and Jesús Aguilar, which means Lewin Díaz has to compete for reps. A premier defensive first baseman, Díaz isn't quite in the same boat as Bleday and Burdick because he received callups each of the past two seasons. When he finally played on a regular basis last September, he posted a .741 OPS with five homers in 93 plate appearances.

Behind the dish, reigning Gold Glove winner Jacob Stallings (.541 OPS) has been handling the 1-2 punch of Sandy Alcantara and Pablo López. Rookie Nick Fortes (.754 OPS) has worked with Triple-A teammates like Cabrera and Garrett, but he got a chance to catch López for the first time in Saturday's 4-0 loss.

"It was good," López said. "I think for the most part, we were on the same page. He's caught a lot of my bullpens as the season has been going on. We had a conversation before the game to come up with a plan, and for the most part we stuck with it."
