• There is a chance Kazuma Okamoto will not get posted after all.

• And finally, our boy Lance Brozdowski created his own projections for some of the players making the move. He’s even more dismissive of anyone making a major impact.

American League

Rays

• The team thinks Jake Mangum and Chandler Simpson can “co-exist,” but believe Jonny DeLuca will play centerfield.

Jake Mangum and Chandler Simpson are coming off impressive rookie seasons. They’re similar players, built to thrive with contact and speed, with Simpson stealing more bases (44 in 109 games) and Mangum the more polished defender. But Neander said they can co-exist in the same lineup, and he noted that moving from George M. Steinbrenner Field back to Tropicana Field could help both, as their skill sets make them “built for bigger parks.”

“Having a lockdown defender in center field is probably as much as our identity that we’ve had as a team for as long as I’ve been here,” Neander said. “[DeLuca’s] greatest strength was to be that type of defender in center field, and not having him, we felt it.

“A healthy Jonny DeLuca will be a huge add to wherever we come out going into camp.”

I think some team will trade for one of these three centerfielders.

Royals

Bobby Witt Jr. saw a drop in stolen bases because of a lower on-base rate and injuries.

There’s so much that goes into baserunning that it’s hard to pinpoint exactly what went wrong. Witt stole more bases this year, but he still felt like he could have had more and pointed to several reasons why he didn’t, including that his on-base percentage dipped (.389 last year to .351 this year) and that he was limited by injuries at times.

I looked into the injury angle. At RotoWire, they marked three instances of a Witt getting hurt (no IL stint):

Injury date (location)

  • July 23rd (knee)
  • Aug 11th (back)
  • Sept 5th (back)

Before the first injury, he was 27 for 34 in stolen base attempts over 102 games. An attempt once every 3.0 games. After the first injury, he was 11 for 13 in stolen base attempts over 55 games, or an attempt once every 4.2 games. A change, but not a major one.

He started running fewer times before the first reported injury. Here are his Stolen Base attempts by month.

Month: SB Attempts

  • Apr: 13
  • May: 12
  • Jun: 2
  • Jul: 8
  • Aug: 6
  • Sep: 6

He was on pace for 70 SB, but then June hit, and he slowed down to 33 SB pace. I could not find a reason for the June decline.

Tigers

Kevin McGonigle, who only played shortstop this minor-league season, is working at third base in the Arizona Fall League.

And with McGonigle, Clark and Josue Briceño (Tigers’ No. 3 prospect, No. 33 overall) likely knocking on Detroit’s door next year, Monday was no different. McGonigle is working at third base in the Arizona Fall League precisely to help his fit for a Detroit debut next season.

“I expect the players that posted dominant years in Double-A to factor into our big league team next year. They’ve earned it,” Harris said. “They posted incredible years as 20-year-olds, very young for the level. I expect their progress to continue, and I expect them to be in Detroit at some point next year.

Twins

• Top prospect, Kaelen Culpepper, added about 3 mph of bat speed.

Following his professional debut in 2024, Culpepper set out to get better. He worked to add bat speed, and according to a club official, he did just that — ticking his swing speed up by about three miles per hour. Then he maintained that throughout the season, and it showed in his results.

National League

Brewers

Garrett Mitchell expects a normal Spring Training.

OF Garrett Mitchell
Injury: Left oblique, left shoulder
IL date: April 26 (transferred to 60-day IL on July 6)
Expected return: 2026
Status: Underwent surgery on July 1 and expects a relatively normal ramp-up to the start of Spring Training.

Shelby Miller will miss all of the 2026 season.

RHP Shelby Miller
Injury: Right UCL sprain
IL date: Sept. 3 (60-day IL; retroactive to Sept. 2)
Expected return: Late 2026 or start of ’27
Status: Underwent surgery to repair the UCL and flexor tendon on Oct. 13 with Dr. Keith Meister and is likely to miss most or all of 2026. Will be a free agent after the World Series.

Diamondbacks

Tyler Locklear will need surgery and will miss part of the 2026 season.

Locklear needs elbow and shoulder surgery this offseason after a collision at first base in September, and his recovery will likely force him to miss the start of next season.

Marlins

Joe Mack made it to AAA and will be added to the 40-man roster this offseason.

Mack, who turns 23 on Dec. 27, appears to be the catcher-in-waiting.

In 2025, Mack received an early-season promotion to Triple-A Jacksonville and helped the Jumbo Shrimp to their first national championship. In 99 games, he slashed .250/.320/.459 with 18 doubles, two triples, 18 homers and 53 RBIs.

Mack will need to be added to the 40-man roster this offseason to be protected from the Rule 5 Draft. As a result, he will receive an automatic invitation to big league camp this spring — his second straight appearance there. This time around, Mack should receive more reps than he got this year.

Nationals

Josiah Gray will be healthy and ready for a full Spring Training after recovering from Tommy John surgery.

The Nationals decided to end Josiah Gray’s rehab and shut him down for the remainder of the season. The right-hander recovering from last year’s Tommy John surgery will now begin his offseason program in preparation for next season instead of making one major league start before the season ends Sunday.

“I think the decision was made because he did his rehab, he was in good spirits, he was feeling good, he’s healthy. And now we want him to go home, relax and start (getting) ready for next season,” Cairo said. “Finally, he’s going to have a whole winter working to be prepared to show that he can pitch in the big leagues, that he can be with us. But he’s going to have a whole winter working out to get stronger and be healthy.”

In three rehab starts across three levels of the minor leagues, Gray allowed no runs over 6 ⅔ innings, with four hits, five walks and five strikeouts. He threw 45 pitches over 2⅔ scoreless and hitless innings while walking three and striking out two in his last start Friday night for Triple-A Rochester.

During Gray’s rehab process, the Nats were more focused on him staying healthy than his mechanics and results.

Hopefully, he found a way to throw strikes (career 4.3 BB/9 and 1.42 WHIP).

Padres

• The team may consider stretching out Adrian Morejon and Mason Miller as starters.

Preller didn’t commit to roles for either pitcher but left open the possibility of stretching one or both back out. “We’ll definitely get Mason’s thoughts and hear what he thinks is best. We’ll see how the offseason plays out, roster-wise. Then we’ll have some clear direction for him of what that looks like,” he said regarding Miller. Preller expressed a similar sentiment on Morejon. “(He’s) a lefty that’s throwing three plus pitches with command and the ability to use him in different places in the game. I think that’ll be a conversation as we get into it, similar to Mason, about what that looks like here for next year.”

Pirates

• MLB.com’s Alex Stumpf thinks Konnor Griffin will start the 2026 season in AAA and quickly work his way to the majors.

Based on conversations I had at the end of the season, I will hazard a guess that Griffin will start next year with Triple-A Indianapolis. If he performs well there, I don’t know how long he can be kept from Pittsburgh. The left side of the infield needs an upgrade. If the Pirates pick up a third baseman and have Jared Triolo start the year as the shortstop, there would be a very clear path for Griffin to reach the Majors.

Reds

• Late in the season was the first time Matt McLain started feeling 100% after having shoulder surgery.

McLain, 26, batted .220 with a .643 OPS in 147 games. He was often dropped to ninth in the lineup by the second half after opening the season batting second.

“Sometimes with shoulders and a year of development [lost], it’s just not as easy as you want,” Francona said.
….
“I do believe he’s just now starting to feel and be 100 percent. I think it’s a year-and-a-half-plus surgery to get back to full strength,” general manager Brad Meador said. “But he should have a full offseason. He should be able to have a good offseason. He knows he needs to have a good offseason. I think he’ll bounce back in a good way next year.”

First off, shoulder injuries can put a damper on a player’s season. Also, McLain didn’t show much improvement with a 76 wRC+ in the first half and 79 wRC+ in the second half. His power metric stayed the same from the first half to the second, while his contact rate dropped. I don’t buy that McLain is back in any way.

Overseas Player Comps: Ponce, Murakami, Imai, and Others


Yukihito Taguchi-USA TODAY Sports

To get an idea of a player’s production when moving from Japan’s Nippon Professional Baseball Organization (NPB) and Korea Baseball Organization (KBO), I compiled a list of players who made the move and their MLB results. With the results, I compiled a list of comps to get a range of possible outcomes. We have several players coming over for their debut, but also returning arm trying to make an impact after 55 uneventful innings 2020-21.

Here they are:

Note: If I missed anyone to find the comps for, let me know. I’ll add them later to this article or possibly to Mining the News.

Angels

Logan O’Hoppe is going to be the team’s main catcher after struggling in 2025.

To this day, the Angels view O’Hoppe as their guy, said Angels GM Perry Minasian. When he comes into spring training next season, he won’t need to earn the job.

“Logan had a tough year, there’s no sugarcoating that,” Minasian said. “But yes, we believe Logan can catch. It’s a really tough position. To break in a young catcher takes time. I’m expecting a better Logan O’Hoppe.”

Batters rarely add power once in the majors and start declining due to better early-career training.

Position players are not becoming stronger in their late 20s, as conventional wisdom suggests. Bat speed and exit velocity are not immune to aging like so many other movement- and speed-based skills in the sport (like pitching velocity).

When players arrive in the major leagues, many of their underlying skills are nearly as good as they will ever be – at least since we’ve had the ability to measure them in the Statcast era.

Driveline director of hitting Tanner Stokey noted that those skills’ aging curves might have been different years ago – perhaps more players did grow into strength and bat speed – but it is a different game in the modern era.

“You just assume players are the most physically gifted they’ve been – they have all the resources in the weight room, the nutrition side, the sleep, recovery side, right? It’s very different than it was back in the day,” Stokey noted. “That stuff is pretty optimized compared to where it was 20, 30, 40 years ago.

Lessons Learned: Season in Review

Hitters Who Played Through a 2025 Injury


Jay Biggerstaff-Imagn Images

With the regular season over, it’s time to find out how hitters performed who didn’t let an injury heal and played through the pain. Whether these hitters cause permanent damage to their bodies or pick up bad habits, they continue to underperform their next season’s projections. Besides collecting the names myself, I’ve asked for some help (article) for this past season’s list.

First, here is a look at how 2024 hitters performed compared to their Steamer projections.
