The San Diego Padres thought their lineup was settled.
Then Luis Arráez left for the Giants… and suddenly the most unpredictable battle of spring training began. ⚾🔥

💥 BREAKING NEWS: Padres’ First Base Battle Explodes as Five Contenders Fight for Opening Day Job
The San Diego Padres entered the offseason believing their offense was already built.
With stars like Fernando Tatis Jr., Manny Machado, and Jackson Merrill anchoring the lineup—and reliable contributors such as Freddy Fermin and Ramón Laureano supporting them—the core appeared set for another run.
Then everything changed.

When Luis Arráez departed in free agency to the rival San Francisco Giants, the Padres suddenly found themselves with a glaring vacancy at first base—the so-called “cold corner.”
And in typical A.J. Preller fashion, the Padres didn’t chase a single expensive replacement.
Instead, they assembled a group of low-risk, high-reward candidates, turning first base into one of the most fascinating position battles of spring training.
With Opening Day approaching, five players are still fighting to claim the job.
5️⃣ Jose Miranda – The Hot Bat, Uncertain Role
Few players have been swinging a hotter bat in Cactus League play than Jose Miranda.
The former Twins infielder has delivered impressive numbers this spring, posting a .375/.464/.667 slash line with multiple extra-base hits and seven RBI.

Defensively, Miranda has also looked steady at first base, recording a perfect 1.000 fielding percentage in limited innings.
Yet Padres manager Craig Stammen continues giving him more time at third base, suggesting the team may value his versatility more than his potential as an everyday first baseman.
For now, Miranda appears more likely to fill a utility role rather than lock down the position.
4️⃣ Gavin Sheets – The Bat Everyone Loves
Few hitters in Padres camp have impressed as much as Gavin Sheets.
His offensive production has made him an exciting addition to San Diego’s lineup.
But the biggest question surrounding Sheets has nothing to do with his bat.

It’s his defense.
Throughout his major league career, Sheets has rarely played first base full time. In fact, he has started more than 20 games at the position only once, when he logged 41 starts in 2024.
While he has looked solid defensively this spring, the Padres may hesitate to rely on him as their everyday first baseman for an entire season.
That likely keeps Sheets in a DH-first role, with occasional starts at first.
3️⃣ Miguel Andújar – The Offensive Splash
When the Padres signed Miguel Andújar to a one-year, $4 million deal, the move was widely viewed as the club’s biggest offensive addition of the offseason.
Andújar’s bat has long been his calling card.

But the Padres have experimented with him at first base during spring training, starting him there in a couple of games.
So far, the results have been encouraging.
Across 11 innings, Andújar has not committed a single error.
Still, the same concern appears here as with Sheets: can the defense hold up across a full MLB season?
For now, Andújar seems best suited as the Padres’ designated hitter, with occasional flexibility in the outfield or at first base.
2️⃣ Nick Castellanos – The Surprise Experiment
Perhaps the most surprising name in this competition is Nick Castellanos.
The veteran slugger has never played first base in the major leagues—not even once.
Yet he has suddenly become a serious contender for the role.
Why?
Because his bat has been electric this spring.
Through nine games, Castellanos has posted a 1.011 OPS, giving the Padres’ offense an immediate spark.
Defensively, the transition has been… acceptable.

For a player learning the position on the fly, Castellanos has held his own.
But the Padres must decide whether “acceptable defense” is good enough for a team hoping to contend.
1️⃣ Ty France – The Quiet Favorite
The leading candidate for the job may be the most familiar name of all.
Ty France.
The Padres originally drafted France, making his return to San Diego feel like a full-circle moment.
While he has historically been considered a bat-first player, France shocked the league in 2025 by becoming the best defensive first baseman in baseball.
After posting a brutal –12 Outs Above Average (OAA) in 2024, France flipped the script completely.
He finished 2025 with +10 OAA, leading all MLB first basemen—and earning his first Gold Glove Award.
Now he’s backing it up at the plate.
In Cactus League action, France has hit .375/.444/.500, continuing to prove he can deliver both offense and defense.
Even more encouraging for San Diego:
France has dominated left-handed pitching, hitting .500 against southpaws this spring.
That could be crucial when the Padres open the season against Detroit Tigers ace Tarik Skubal, arguably the most dominant left-handed pitcher in baseball.
The Decision Approaches
With Opening Day rapidly approaching, the Padres must soon decide who will anchor first base.
Will they trust France’s defense?
Ride the hot bat of Sheets or Miranda?
Experiment with Castellanos?
Or give Andújar a bigger role?
One thing is clear.
What began as a simple roster gap has turned into one of the most fascinating competitions of the Padres’ spring camp.
And whichever player wins the job could become a key piece in San Diego’s push for October.
