Colson Montgomery’s Reset Is Powering His White Sox Breakout

The Arizona reset helped Montgomery unlock the kind of in-game power the White Sox had been waiting to see.

That power has carried into 2026. Montgomery finished April with eight home runs, a .495 slugging percentage, an .831 OPS, and a 127 wRC+ through 128 plate appearances. Over his last 12 games, he has hit .319/.418/.681 with five home runs, 12 RBI, and a 1.099 OPS.

The longer view is even more convincing. Since his first major league home run on July 22 of last season, Montgomery has hit 29 home runs in 87 games. That puts him tied for second in baseball over that span, behind only Kyle Schwarber and tied with Aaron Judge and Cal Raleigh. He also ranks third in RBI and 11th in fWAR. Among shortstops, his fWAR ranks fourth.

That production is helping reshape the middle of Chicago’s lineup. Montgomery’s recent four-game homer streak overlapped with the offense starting to turn it on after the West Coast trip, with Munetaka Murakami homering in five straight and Miguel Vargas going deep in three straight during the same run. Having more than one source of power will be key for this lineup going forward.

The contact data supports Montgomery’s results. He is averaging 90.0 mph off the bat with a 42.0 percent hard-hit rate and a 15.9 percent barrel rate. His barrel rate sits in the 90th percentile, while his bat speed ranks in the 94th percentile. He has also raised his launch angle sweet-spot rate from 35.8 percent last season to 40.6 percent this year.

The pull-side damage has become a major part of the profile. Montgomery’s pull rate has jumped from 48.6 percent in 2025 to 55.1 percent this season. That number is likely to drop over a full season, but it shows why this run has been so dangerous. When Montgomery lifts the ball to his pull side, it has a real chance to leave the yard.

That is why the home run off Soriano mattered beyond the box score. Soriano had allowed one run all season and had not been scored on in 25 2/3 innings before Montgomery got to an 87 mph knuckle curve and drove it out to right-center at 102.1 mph. The young hitter proved he could come through in a big spot in front of his home crowd.

The White Sox do not need Montgomery to be perfect for this power to matter. They need him to keep doing damage. The batting average will move around, and the swing-and-miss is its own conversation, but the power is no longer theoretical. It has become one of the clearest strengths on the roster.

Montgomery’s Defensive Leap

If the power has made Montgomery one of the White Sox’s most important bats, the defense has made his profile much harder to dismiss.

Shortstop was never a lock. Montgomery’s size always created questions about whether he would eventually move to third base, even as the White Sox continued to believe in his athleticism, quick hands, and internal clock. The more important development is that he has started to prove it against major league speed.

The early returns have been more than serviceable. Montgomery posted +7 Outs Above Average as a rookie in 2025, including +6 at shortstop across 60 games. This season, he has a +4 Fielding Run Value and +4 Outs Above Average, with most of that work coming at shortstop. Baseball Savant has him in the 97th percentile in Fielding Run Value and the 98th percentile in range.

That is not the defensive profile of a player the White Sox need to move off the position. It is the profile of a player who is thriving at one of the most demanding spots on the field.

Montgomery is not doing it with elite sprint speed or top-of-the-scale arm strength. The defense has worked because he has become a cleaner processor at shortstop. He is reading the ball well off the bat, putting himself in better spots, and finishing routine plays.

That matches how he talked about defense during spring training, when he pointed to pregame work, effort, and his internal clock as the foundation for knowing when to speed up and when to let the play come to him.

That internal clock has helped the arm play better than the raw strength might suggest. If Montgomery reads the speed of the runner and gets the ball out on time, he does not need to overpower every throw. He just needs to be accurate, efficient and under control. That has been one of the biggest differences between the old projection and the current version.

The organization may eventually revisit the infield alignment. Montgomery has shown he can handle third base in looks, and his frame could make that move easy if the roster pushes him there. For now, that feels more like a future roster question than a current defensive issue.

Right now, Montgomery is giving the White Sox every reason to keep him at shortstop. The bat has become what was projected, but the glove is what has made the breakout feel more complete.

The White Sox Need This

Montgomery’s jump matters because the White Sox are not built with much margin for error yet.

They have started to look more competitive, and the 13-13 finish in April was a real step forward for the organization after where it has been the last few years. But staying around the division race requires more than improved vibes or a few well-timed wins. It requires young players to turn into longer-term answers, especially in the middle of the lineup.

That is why Montgomery’s development has been so important. The White Sox need power from more than one spot in the lineup, and they need it from players who can stay on the field and provide value in multiple ways.

Montgomery is checking both boxes. He gives Chicago another bat capable of changing a game with one swing, while also giving them defensive value at a premium position.

That combination is what separates him from a typical power breakout. If Montgomery were a corner bat with the same swing-and-miss concerns, the offensive bar would be higher. At shortstop, the math is different. A 30-homer bat with positive defensive value can anchor a lineup and help stabilize a roster that is still sorting through young pieces.

It also changes how the team can win games right now. The White Sox are not going to grind through every night with a deep, finished offense. They are still going to have empty stretches. But when Montgomery, Murakami and Vargas are all capable of producing power at the same time, the lineup has a different feel. There are more ways to flip a game before it gets away.

That was the takeaway from the Angels series. Montgomery did not carry the sweep by himself, but his role in it showed why his emergence matters. He beat Soriano with power, helped keep the finale alive defensively and ended the series with the first walk-off hit of his career. For a team trying to prove it can hang around longer than expected, that is the kind of player who changes the conversation.

The Swing-and-Miss Hurdle

The one thing keeping Montgomery’s profile from feeling fully settled is the swing-and-miss.

That does not erase what he has already done. It is part of why the next step is so clear. Montgomery finished April with a strikeout rate near 30 percent, and his whiff rate still sits near the bottom of the league. The expected numbers also trail the surface production; he has a .219 xBA and .337 xwOBA compared to the louder results in the box score.

Montgomery’s power is real, but the contact quality is still uneven enough to leave room for volatility. When he gets the ball in the air, the potential for damage is obvious. When pitchers get him to expand or beat him in the zone, the at-bats can end quickly.

The encouraging part is that this does not require a total offensive rebuild. Montgomery has already lowered his chase rate from last season and has been more selective about when he wants to do damage. The issue is more about making enough contact inside the zone to let the rest of the profile breathe.

That is why even a small improvement could change his ceiling. Montgomery does not need to turn into a high-contact hitter to become one of the more valuable shortstops in the league. He just needs to move the strikeout rate closer to the high-20s, keep taking his walks and give the power more chances to show up.

Montgomery’s splits point to where the next step can come from. He has produced a 186 wRC+ against left-handed pitching, while the production against right-handed pitching has been more modest overall (108 wRC+).

However, the power has not been limited by platoon. He has four home runs against lefties and four against righties, which is an important distinction. Left-handed pitchers may still be figuring out how to shape an attack plan around his bat path and avoid his damage zones, but Montgomery has shown he can impact the game regardless of matchup.

So, the next step is about raising the baseline against righties. If the average and on-base skills improve in those matchups, Montgomery becomes much harder to navigate.

Lineup context may also factor into this early split. Against left-handed starters, Montgomery has often hit lower in the order, adding power deeper in the lineup and balancing the Murakami-Vargas core.

This could become one of Will Venable’s more interesting challenges as the roster gets healthier. When Kyle Teel returns, the question will not just be who plays. It will be how Venable structures a lineup with multiple left-handed bats capable of changing a game with one swing.

For now, the strikeouts are the tradeoff that comes with the power. The White Sox can live with that as long as Montgomery keeps hitting the ball out of the park and defending shortstop. But if the contact rate takes even a small step forward, he won’t just be an exciting young power bat. He could be one of the better all-around players at the position.

Chicago’s Infield Puzzle

Montgomery’s progress also changes how the White Sox can think about the rest of their infield.

The organization has more shortstop talent on the way. Caleb Bonemer has been off to a scorching start in 2026 and has already started getting more looks at third base. Billy Carlson, the White Sox’s first-round pick last year, gives the system another high-end defender at shortstop.

Chicago also holds the No. 1 pick this July, where all signs continue to point toward UCLA shortstop Roch Cholowsky.

This could create a long-term puzzle, but Montgomery’s emergence makes it a good problem to have.

If Montgomery were struggling defensively, the conversation would be different. The White Sox would have to think harder about whether a move to third base should happen sooner, especially with more infield talent on the way. Instead, he has given them every reason to let the current setup play out.

That does not mean third base is off the table forever. His size, athleticism, and arm could still make him a strong fit there if the roster eventually pushes him in that direction. The reaction skills and internal clock that help him at shortstop should translate well to the corner.

The offensive burden would change, though. A power bat at third base is valuable, but the same power at shortstop carries more weight. That is why Montgomery staying at short matters so much. It keeps his bat at a premium position while giving the White Sox time to let the rest of the infield picture develop around him.

For now, there is no reason to rush the decision. Montgomery has played his way into the present shortstop job, and the rest of the system can sort itself out behind him. If anything, his development gives the White Sox more flexibility than they had a year ago.

As the draft approaches and the organization’s next wave comes into focus, this should make for one of the more interesting summers on the South Side in a while. Montgomery is giving fans a reason to believe the future is not as far away as it once felt. If the weather heats up and the bats stay hot, the White Sox might finally have something worth watching grow.
