MLB Debut and Initial Performance

He made his MLB debut with the Reds in late 2022. That marked the end of his long minor league grind. His defense stood out right away, but like a lot of young guys, he needed some time to adjust at the plate.

During his stint in Cincinnati, Siani worked hard to prove himself as a reliable outfield option. He leaned on his speed and glove while still working on his bat.

Time with the St. Louis Cardinals

Siani’s career took a new turn when the St. Louis Cardinals claimed him off waivers on September 2, 2023. The Reds had designated him for assignment just a few days earlier.

With the Cardinals, Siani signed a one-year contract worth $770,205. He joined an outfield group with veterans like Lars Nootbaar, Dylan Carlson, and Jordan Walker.

During Spring Training 2025, Siani fought to earn his spot in the Cardinals’ outfield rotation. He’s benefited from playing alongside stars like Nolan Arenado and Paul Goldschmidt, who’ve given him plenty of advice.

At Busch Stadium, Siani has carved out a role as a defensive replacement and occasional starter. His speed lets him cover a ton of ground out there.

Key Teams and Player Partnerships

Throughout his career, Siani has formed important partnerships that have helped him grow. At St. Louis, he’s learned a lot playing with All-Stars like Tommy Edman and Nolan Gorman.

The Cardinals’ pitching staff, which includes veterans like Kyle Gibson and Lance Lynn, has really benefited from Siani’s glove. He’s turned plenty of would-be hits into outs.

Siani has also clicked with outfielders Brendan Donovan and Alec Burleson. Together, they form part of the Cardinals’ young core and push each other to get better.

In the clubhouse, Siani fits right in with the Cardinals’ winning culture. He learns from the vets and brings some youthful energy to the mix.

His willingness to take on any role has made him a valuable piece of the roster puzzle.

Significant Games and Highlights

While with the Cardinals, Siani has pulled off some memorable plays. His defense stands out—diving catches, strong throws, you name it.

He’s also shown flashes of clutch hitting, coming through with timely base hits in tight spots. These moments don’t always make headlines, but they’ve helped the Cardinals win important games.

As Siani keeps developing, he’s pushing to play bigger roles in big games. His ability to help on defense, at the plate, and on the bases makes him especially valuable during the pressure of late-season and playoff baseball.

The Cardinals picked up Siani as part of their strategy to add athletic, cost-controlled outfield depth. President of Baseball Operations John Mozeliak and owner Bill DeWitt III saw value in his defense.

This contract puts Siani in the Cardinals’ plans for 2025. His salary is modest, but it gives him a shot to prove himself at the big league level.

Free Agency Experience and Negotiations

Even though he’s still early in his career, Siani has already seen how the business side of baseball works. Moving from the Reds to the Cardinals shows how young players often bounce around before they hit free agency.

Siani’s net worth sits at about $2,053,844, based on his career earnings so far. That number should climb as he racks up service time and maybe gets to arbitration.

The Cardinals clearly value Siani’s defense in centerfield. The current contract is a win-win: Siani gets big league playing time, and the Cardinals get a speedy, athletic outfielder who can help right away.

Endorsement Deals and Sponsorships

Siani hasn’t landed many big endorsement deals yet. He’s still a developing player, and his MLB debut wasn’t that long ago, so his marketing profile is pretty low compared to established stars.

Baseball gear companies sometimes offer young players like Siani basic endorsement deals, but details on those aren’t usually public.

He took rehab seriously and got back on the field without any real setbacks. Honestly, that kind of discipline isn’t easy to stick with.
