5 dream trade targets for the St. Louis Cardinals

Dream candidate #2: RHP Zach Eflin

When the Tampa Bay Rays signed right-handed pitcher Zach Eflin prior to the 2023 season, he immediately became the franchise's most expensive free agent. The 3-year, $40 million deal had him making $11 million in the first two seasons and $18 million in the final season which would be next year.

While most Cardinal fans see $18 million and think of Miles Mikolas and Adam Wainwright, Eflin's value far exceeds his dollar mark. The Tampa Bay Rays organization is known for trading players before they enter the final years of arbitration let alone free agents worth 8 figures.

Tim Kelly of Bleacher Report listed the Rays as probable sellers at the deadline recently; they sit just 4 games back of the Wild Card, but they are in 4th place in the American League East. This may be the year the Rays decide to trade off expiring contracts and expensive players to retool. With the bulk of their rotation on the injured list, a retool this year leading into 2025 with a restocked starting pitching staff may be their best bet.

Due to the impending return of key starters next year like Shane McClanahan, Drew Rasmussen, and Jeffrey Springs and Eflin's hefty salary in 2025, he could become expendable this year. The Cardinals should jump on that trade. $18 million is a sizeable chunk of change, but it would likely mean the Cardinals can stray away from using high prospects to lure Eflin away from the Rays.

Eflin, 30, has a 4.12 ERA, 3.78 FIP, and he's walked the fewest amount of batters this year in 74.1 innings. In fact, Eflin has only walked 5 batters this year out of the 310 that he's faced. He won't strike out the side often (6.9 K's per nine innings), but he won't get himself into trouble with free passes.

Zach Eflin would be a huge addition to the Cardinals' rotation for the remained of this season and next year. He would slot in nicely near Kyle Gibson and Miles Mikolas in the middle of the rotation, and he wouldn't cost much to acquire in a trade.

Dream Candidate #3: LHP Tanner Scott

The Miami Marlins will be sellers this year; that's a fact. When Peter Bendix traded offensive whiz Luis Arraez to the Padres in early May, the signs were clear that the Marlins weren't planning on contending this year or next. With that in mind, teams have begun eyeing the Fish for trade candidates.

While Jesus Luzardo may be the most obvious pick here, I'm taking a different route. Luzardo's 5.30 ERA is a career-high, and although he had two strong years in 2022 and 2023, he has lost his effectiveness on nearly all of his pitches.

Rather, the Marlins player that intrigues me most would be reliever Tanner Scott. Scott will be a free agent at the end of the season, so he's a true rental. Rental relievers, regardless of how dominant they are, rarely fetch a top-100 prospect, so the Cardinals can hold on to key guys like Victor Scott II, Tink Hence, Thomas Saggese, and Quinn Matthews. It's possible even Tekoah Roby will be spared.

Scott has thrown 32 innings in relief this year, and he has a 1.69 ERA, 3.89 FIP, and a 1.156 WHIP. His 25.8% K rate is nothing to scoff at, and there's room for growth there, as that's the lowest mark of his career. This is the second year in a row of dominance for Tanner Scott; last year, he had a 2.31 ERA and a 2.17 FIP. He's managed to generate lots of soft contact this year, and his elevated groundball rate will play well with the Cardinals' defense.

Scott can help bolster the back end of the bullpen that is lacking a lefty option outside of JoJo Romero. While Matthew Liberatore has been better out of the bullpen, he's best utilized as a swingman for multiple innings. Scott can be another late-game option for manager Oliver Marmol.

Dream candidate #4: LHP Garrett Crochet

All year, Cardinal fans have been covetous when looking at what the San Francisco Giants did with their former reliever, Jordan Hicks. The Giants did what the Cardinals couldn't do: return Hicks to his rightful spot as a starting pitcher. There's no guarantee Hicks continues to pitch the way he has once he eclipses a certain amount of innings, but for the time being, it's a masterstroke by the team.

The same can be said of the Chicago White Sox and Garrett Crochet. The Sox prepared him this past offseason to be a starting pitcher, and he hasn't let them down. He's already thrown 88.2 innings this year -- more than half of his career total. That's a bit of a concern down the road for this year. However, Crochet isn't a free agent until after the 2026 season. That gives whichever team acquires him 2.5 years of control.

What makes Crochet a true dream candidate would be his strikeout abilities. He leads the American League in strikeouts right now, and he has been sending batters back to the dugout with at a ridiculous 35.2% clip. A left-handed starter with a propensity to strike batters out is something the Cardinals haven't had since Jaime Garcia, and he pales in comparison to Crochet.

Crochet's value is the highest it will ever be right now, and there are plenty of teams with better farm systems who are in search of a top-end starting pitcher. John Mozeliak will have to bring his A-game (and top prospects) to the table when dealing for Crochet. It may be a pipe dream, but acquiring Crochet would vaunt the Cardinals into a playoff conversation they haven't been in for quite some time.

Dream candidate #5: OF Kyle Tucker

The biggest outfielder who may get dealt this deadline is center fielder Luis Robert Jr. He's talented, he's performed outstandingly well, and he's young. The issue, however, is that Robert has yet to play more than 100 games in a single season. Injuries have brought him down.

Kyle Tucker, on the other hand, has been pretty durable for most of his career. He's currently out with a shin injury, and it's taking longer to heal than expected, but Tucker has been one of the best all-around outfielders in baseball for 5 years now.

The 27-year-old lefty is slashing .266/.395/.584 for a wRC+ of 175. He's already slugged 19 home runs in just 60 games, so his power is tantalizing. Tucker isn't a free agent until after next season. This would make him expensive given his team control, his age, and his production. The Cardinals would have to muster up quite the package to land the 2-time All-Star.

Tucker's defense is also noteworthy. He has one Gold Glove to his name, and he's been reliable in right field this year according to all defensive metrics. He's racked up 7 Defensive Runs Saved, 1 Out Above Average, and he has a 3.4 score according to Ultimate Zone Rating.

Landing Kyle Tucker at the trade deadline is a bit of a pipe dream. The Astros will likely remain close enough to the Wild Card to not sell, he's an elite baseball player, and the Cardinals may not be able to beat other teams with better farm systems. However, should John Mozeliak trade for the young outfielder, the team's offensive profile will change dramatically.
