While the Seattle Mariners are still searching for stability in the fiercely competitive American League, a young name has unexpectedly become the center of attention throughout MLB. Not because of his impressive home runs, but because of his outstanding defensive abilities, leading the league.

According to a key defensive metric, Cole Young is currently the best guard in MLB – and that could completely change the Mariners’ future.

In a season where Seattle needs a fresh boost, Young is exceeding expectations. Once considered a promising prospect needing time to develop, the 22-year-old is now proving he can become a central figure immediately.

According to Seattle Sports, Young is leading the MLB in Defensive Runs Saved (DRS) with a +4 rating at the start of the season. This is an metric estimating the number of points a player saves for their team through defensive ability, and it’s extremely rare for a young domestic player to lead the entire league.

In other words: Cole Young isn’t just playing well. He’s making a real difference.

Just last season, many were still questioning whether Young was ready for MLB. In his rookie year in 2025, he shot .211 with an OPS of .607, had memorable moments but also went through many difficult periods. Many believed Young needed more time at Triple-A before taking on the responsibility at Seattle.

But instead of giving up, Young turned those doubts into motivation.

This past winter, he threw himself into training, improving his physical fitness, footwork, reaction speed, and especially his turning skills for double play at second base. Those small details are now making a huge difference on the court.

The result is a completely different version of Cole Young entering 2026: calmer, sharper, and more confident.

Defense is always the foundation for teams that want to go far. And the Mariners possess a valuable weapon in the paint.

With Young anchoring the second base, Seattle has an extra layer of insurance for its pitching staff. Dangerous groundballs are neutralized. What seemed like a single hit now turns into an out. Those small moments don’t always appear in the highlights, but they decide the outcome of the entire season.

In modern baseball, where every advantage is calculated by data, a player who can consistently “save runs” is as valuable as a slugger hitting 30 home runs.

And that’s why the Mariners are incredibly excited.

Not just a defensive specialist, but his bat is also making its mark.

The scariest thing for the rest of MLB is that Young is no longer just a defensive specialist. He’s starting to contribute with his bat as well.

According to early season statistics, Young is batting .265 with an OPS of .802, has 2 home runs and 8 RBIs after just the first few games of the season. This is a huge step up from last year and a sign that he’s gradually becoming a true two-way player – both saving points and creating points.

If this trend continues, the Mariners may have found their long-term answer at second base – a position that has plagued them for years.

Seattle doesn’t lack talent, but what they’ve always lacked is consistency. Championship teams are often built around young players who are both effective and can maintain consistent performance over the long term.

Young fits that model perfectly.

He’s young, inexpensive, has years of contract control, and most importantly: he’s developing very quickly. If he continues to improve, Young could become a mainstay alongside players like Julio Rodríguez, Cal Raleigh, and the Mariners’ quality pitching.

In other words, this isn’t just about a few early-season statistics.

This could be the opening chapter for a new Seattle star.

MLB is starting to take notice.

In a league full of superstars, it’s rare for a young Seattle native player to attract nationwide attention solely for his defense. But Young is doing just that.

Opposing teams will soon have to adjust their play. Fans are starting to realize that whenever the ball is hit toward him, a sense of security immediately sets in. And analysts are viewing Young as a true breakout candidate for 2026.

The scariest thing? He’s only just begun.

Cole Young is only 22 years old. He still has time to get stronger, smarter, and more dangerous on the batting court. If he’s already the #1 MLB guard by a large metric, how much higher can his potential go?

Seattle has been waiting for a new home court star to build their future.

Perhaps they’ve just found him.

And if the rest of MLB hasn’t really taken notice yet… they should start now.
