Is Grady Sizemore Becoming an Outfield Whisperer?

When the Twins hired Grady Sizemore this offseason, the move wasn't accompanied by the same fanfare as adding a high-profile bench coach or pitching guru. Derek Shelton brought the former All-Star aboard as the club's first base coach with an emphasis on working with the outfielders, hoping one of baseball's premier defensive center fielders could pass along some of the instincts that made him a two-time Gold Glove winner.

Halfway through the season, that investment is paying off. Minnesota's outfield defense has taken a noticeable step forward, and several players who entered the season with defensive question marks have become reliable contributors on the grass. Whether it's refining an established outfielder's routes or helping an infielder learn an entirely new position, Sizemore's fingerprints are becoming increasingly visible.

It's fair to wonder whether the Twins have found their own outfield whisperer.

A Coach Who's Been There

Sizemore's playing career ended far sooner than anyone expected. Once on a Hall of Fame trajectory during his prime in Cleveland, injuries ultimately forced him to retire after the 2015 season at only 33 years old. Coaching wasn't initially part of his plan, but conversations with current players eventually reignited his passion for the game.

His coaching journey started modestly with an internship in the Diamondbacks organization before the White Sox promoted him through their staff. By the middle of the disastrous 2024 season, Chicago asked him to serve as interim manager before he transitioned into the organization's offensive coordinator role in 2025.

Shelton knew exactly what he was getting when he assembled his first coaching staff in Minnesota. The two overlapped in Cleveland during Sizemore's playing days, and Shelton wanted coaches who had experienced success at the highest level.

"The biggest thing with Grady … is just getting him to talk," Shelton said. "The wealth of knowledge, he's so humble. I was fortunate to coach Grady Sizemore because he was such an elite player. There is so much in there."

Players have gravitated toward Sizemore's calm personality and willingness to teach. Trevor Larnach has repeatedly praised him for helping with every aspect of the game, while Shelton describes Sizemore as someone with a unique presence who naturally connects with players.

Sizemore, however, refuses to take much credit. "I enjoy working with them and pushing them," Sizemore said. "They're teaching me as much as I'm teaching them. Every day, I'm asking them for feedback on what I can do better." That collaborative approach appears to be producing results.

Austin Martin's Defensive Turnaround

Few players illustrate Sizemore's impact better than Austin Martin. Martin's rookie campaign in 2024 was rough defensively. He finished worth -6 Outs Above Average and -9 Run Value in the outfield as inconsistent routes and reads overshadowed the athleticism that made him such an intriguing prospect.

Last season didn't provide many opportunities to improve. Martin suffered an injury at Triple-A before earning a late-season promotion following Minnesota's trade deadline selloff, limiting his defensive reps at the major league level.

This year has looked dramatically different. He has a 2 Run Value and 1 OAA in the outfield. Martin has played with more confidence, taking cleaner routes while making better first-step reads off the bat. The athletic ability was never in question. Under Sizemore's guidance, the consistency has started matching the talent.

Luke Keaschall's Position Change

Keaschall's season has featured one of the more fascinating defensive developments in the organization. Originally expected to handle second base, Keaschall struggled throughout the first half. His -7 Outs Above Average at second made him one of Minnesota's least effective defenders at the position, forcing the Twins to consider alternatives.

Rather than limiting his playing time, they moved him to the outfield. Working closely with Sizemore, Keaschall has adapted remarkably quickly. In only 15 opportunities, he's already posted 1 Outs Above Average, a dramatic improvement that reflects both his athleticism and the instruction he's received.

The transition hasn't been flawless, but the encouraging moments have far outweighed the mistakes.

During Minnesota's recent homestand, Keaschall made a highlight-reel running catch while also demonstrating improved instincts on balls hit toward the wall. After misjudging a carom that turned into a triple against Colorado, he quickly applied that lesson days later against Houston. On Cam Smith's second-inning drive, Keaschall correctly recognized the ball would either clear the fence or rebound sharply off the wall. Instead of drifting too close, he backed away, played the bounce perfectly, and held Smith to a double.

Those are the types of adjustments coaches love to see. "It's more learning as we go, but I feel good out there, confident, relaxed," Keaschall said. "I've got good people around me, so that helps a lot, too."

For a player who looked overwhelmed at second base just weeks earlier, the early returns in right field have been remarkably encouraging.

More Than Just Technique

What makes Sizemore's impact stand out isn't simply the defensive improvements. It's the relationships he's built. Players consistently praise his humility, communication, and willingness to listen. Rather than presenting himself as a former star with all the answers, Sizemore approaches coaching as a collaborative process.

That's likely one reason why players have embraced his instruction so quickly. Whether he's helping Martin unlock the athleticism that always existed or guiding Keaschall through a midseason position change, Sizemore has become an important resource throughout Minnesota's clubhouse.

None of those improvements happened by accident. Great coaches rarely seek the spotlight, and Sizemore has consistently redirected praise toward his players. Still, the evidence continues to mount that Minnesota's investment in one of baseball's former elite defensive outfielders is paying dividends.

If these early returns continue, the Twins may have found far more than a first base coach—they may have found the outfield whisperer they didn't know they needed.

Sizemore was one of my favorite players to watch on opposing teams. He always played the game the way a manager wants to see it played - make the right plays every time, be a tough plate appearance, and run with efficiency. 

What a bonus that Sizemore is willing and capable as a coach because that isn't a given with former stars. Coaching is a humble job. The Twins got lucky bringing Sizemore to the club.

Nice article, thanks! I was intrigued when Shelton brought Sizemore on board, remembering him as an outstanding player at Cleveland. Most coaches don’t show up with his pedigree as a star player. I actually wonder from time to time what insight he’s offering runners at first base, and what goes on before and after games is clearly making a huge impact.

[Mike h]

I love this kind of article.  It gives me hope.

[Casey Anderson]

Great article. I would imagine that Sizemore would be an attractive candidate for other teams after the season. Hopefully the Twins can hold on to him. 

[FlyingFinn]

Kudos to Sizemore. The Twins outfield also suddenly looked much better after Wallner went to St. Paul.

[Fatbat]

What an awesome guy! We obviously need coaches like him that bring out the best in players and their development. I hope he sticks around to help the youngsters that will be coming over the next few years!!

Sizemore is a god send , choosing coaches that can teach is difficult  , Falvey and baldelli seemed to think that AAA was all the development they needed and players weren't successful in playing quality baseball at the mlb level , players are taking a big step from level to level and need good coaching for success , Sizemore is acheving results more than any coach under Falvey and baldelli in my opinion  ...

He was a great player that had a short career due to injuries  ...

We have a keeper in Sizemore  ...

[rdehring]

Great article and comments.  Respected the heck out of Sizemore when he was playing.  And even more so now as a coach.  Let's also give some credit to Shelton for getting him on his first staff with the Twins.

[Peter Gravett]

IMO his greatest impact has been on Larnach, who's D has improved significantly this year. Not so much with Walner.

That's really all that needs to be said. The "outfield whisperer," stuff is silly.

I don't know that any of us here can say what kind of impact Sizemore has had, but Martin looked markedly better last year than the year before, and Keaschall has played OF since he was 18 in the Cape Cod league. He played CF coming up through the minors. The suggestion that he is brand new to the outfield is flat out incorrect.

Sizemore was an incredible player, and I assume he's a smart, quality coach since the White Sox had him in the interim manager position. But the examples provided in this article are not very convincing.

[Jacksson]

Sizemore need to put in additional time with Martin.  Martin looked terrible in RF when in a game not that long ago when the charitable hometown scorer gifted batters in successive innings with a triple and then a double on what were clearly fielding errors.

Yeah I'm not saying Sizemore isn't a good coach, but the "outfield whisperer," stuff is such a reach. The Twins literally sent the worst defensive OF in baseball to AAA, that's pretty much it. Like you said, Martin looks about the same. Larnach looks about the same. The math doesn't seem to hard here. I don't see the need to stretch it into something it's not.

Sizemore is a big upgrade from the recent past. But Buxton also helped a lot in mentoring the new OFers
