Just over one week on the job, interim manager Chad Tracy has started to make his imprint on the Boston Red Sox. Not with wholesale changes, but subtle moves.

Even with a roster full of players he’d managed previously at Triple-A Worcester over the past five years, Tracy knows there’s a delicate balance.

“There’s a good bit of observation early on for a couple of reasons,” Tracy said. “One, because it’s the smart thing to do, and two, if you just come in and start making changes, you make the group feel like you haven’t even been here, how do you know what’s going on? But I’m also aware that I do know the guys. And if I see something approach-wise, I talk to them a little bit about what I feel will help us get on track.”

The change of leadership in the dugout may have been swift, with chief baseball officer Craig Breslow firing Alex Cora and several coaches, but change on the field takes more nuance. Here’s a look at what we’ve learned over the first week and a half of Tracy’s tenure.

Infield defense

A league source said that Breslow and Cora disagreed in spring training about where to play Caleb Durbin and Marcelo Mayer. Breslow wanted Mayer at third with Durbin at second, but Tracy said there’s no plan to make that switch at this point.

“I like where they’re at,” said Tracy, who complimented what’s been a solid defense the past several weeks. “Especially right now, both of them are playing really well and Durbin has been exceptional at third base, his defense. So I like where it’s at and switching things like that in the middle of a season, especially at this level, is hard to do.”

Durbin, who is tied for the league lead at third base with 6 Defensive Runs Saved, has appreciated the consistency in pregame work, especially as he struggles at the plate. He could be optioned to Triple-A Worcester at some point to figure out his offense, but the defensive stability he’s provided at third has helped at least one aspect of the team operate smoothly.

“From my experience in Milwaukee last year, that was a really good infield defense and the work we do here is very similar,” said Durbin, who noted that reps before the game have been especially important to get in a rhythm.

“Once the game starts, building that relationship with Flo, he’s kind of positioning us every pitch, that’s been really good,” Durbin added, in reference to José David Flores, who previously managed the infield group and has maintained those duties as the interim bench coach.

Second-base reps for Ceddanne Rafaela?

While Mayer has a hold on second for now, Tracy was asked about his thoughts on occasional playing time for Rafaela at second. The Red Sox prefer Rafaela in center, but Tracy didn’t rule out using him at second if needed. Cora had held a similar stance, though the Red Sox haven’t played Rafaela at second yet this season, despite 19 games there last season.

“Me and Flo have continued to talk about the possibilities of getting him enough ground balls to where, if we needed to do something, he needs to pop into the infield, he’s very capable,” Tracy said.

In-game managing tactics

Flores, who was his bench coach in Worcester for three years, has been key for Tracy in the dugout. Though Tracy has managed close to 1,000 minor-league games, the speed of the major-league game is noticeable, with instant replay and more frequent mid-inning pitching changes among myriad other changes.

On Saturday night, Tracy emptied his bench in a series of double switches to try to win a game against the Houston Astros, and Flores was helpful.

Tracy had Andruw Monasterio pinch-hit for Mayer with a lefty reliever entering the game. Houston countered by bringing in a righty, but Tracy followed by replacing Monasterio with Masataka Yoshida, who drew a walk to load the bases. Then, Tracy sent in Isiah Kiner-Falefa to pinch-run for Yoshida. Rafaela struck out to end the threat, but it was a complex set of moves hinting at some aggressive managing.

“Especially the way (the game) had gone up to there, you look at that and go, ‘This could be it,’” Tracy said of using the whole roster. “So you take your shot there to try to get back in the game.

“We don’t do much of that in Worcester,” he said. “It was great. Flo was right there with me, we were talking through it.”

How to use Yoshida

As for Yoshida, he’s started just one of eight games since Tracy took over. Rather than trying to weave Yoshida into the starting lineup more consistently as Cora had, Tracy was more definitive about using Yoshida as a weapon off the bench.

“It’s not an easy situation, he’s a good hitter,” Tracy said. “But we’re in the same spot we were. He can hit. But then you look at the other four guys too, the speed and the versatility and what they bring to the table, and they’ve got to play. I do think that one thing is clear. You’re not gonna always use him, but when Masa is sitting there on the bench and available, if there’s a lane with a righty (reliever) where they can’t make a move, that’s a good thing for us.”

Yoshida went into Monday hitting .280 in 61 plate appearances, but is 2-for-5 with two walks as a pinch-hitter.

Jarren Duran at leadoff, Roman Anthony hitting third

Jarren Duran began hitting leadoff again two days before Cora was fired, but Tracy has stuck with him in the top spot. Aside from one off day, he’s led off every game he’s started since Tracy took over.

One change, though, has been sliding Roman Anthony into the three-hole with Willson Contreras hitting second and Wilyer Abreu fourth. Despite just seven runs in their series against Houston over the weekend, Tracy was encouraged by the lineup’s movement, feeling it’s a matter of time before it coalesces.

“I feel it, the guys feel it, the frustration, we all want one of those to come with bases loaded,” he said. “Of course we do, because that’s runs. But the first step was let’s get people on base a lot, and we did that, but we just need to get the hit. … We have people trending as far as the at-bat quality, that was a big message of mine. Talked to you guys about it, like I need multiple qualities (at-bats), two to three, out of everybody. And if we do that, we’ll have traffic. We just got to execute.”

With Anthony in particular, Tracy doesn’t want to move him further down the lineup for now. Anthony exited Monday’s 5-4 win over the Tigers with right wrist discomfort in the second inning.

“The thing I think I’ve said about him before is when Roman is bad, he’s still OK because he still finds his way to first,” Tracy said, noting his 13 walks in 14 games. “Plainly put, when Roman’s really, really going well, he’s not swinging out of the zone, he’s driving the ball in the air, and he hits the ball in the air and drives it to the opposite gap, too.”

Tracy also said he’s looking to give Mayer more at-bats against lefties to continue testing him in the right spots.

“He looks confident,” Tracy said. “He’s swinging the bat well, he’s taking good at-bats, he’s mostly staying off stuff out of the zone, he’s ready to hit fastballs when they’re in the zone. It’s been a little bit (for) the better part of a week now that the bats have really improved. So hopefully keep him moving in the right direction.”

Communication with Breslow

One of the biggest keys to the job for Tracy will be how he works alongside Breslow. In the early going, as expected for a newly hired manager, Tracy suggested that the communication has been easy and that Breslow hasn’t been heavy-handed while also seeking Tracy’s feedback.

“I talk to him a couple of times a day,” Tracy said. “We talk before the game. We talk after the game. But he’s been amazing as far as, like, wanting to know what I think and has not, at this point, put me in any position saying you need to do this or you need to do that. Like, he knows I know the guys, too. So, collectively, me and Bails (pitching coach Andrew Bailey) about pitching, or me and Flo about some of the infielders or hitting, they want to hear my thoughts. But there’s conversations daily. At the end of the day, I’m armed with information. It’s my decision to do what we want to do.”

Style among players

More than half the roster has played for Tracy in Worcester, making the massive changes slightly easier on the clubhouse. Though wins haven’t come easily, several players noted the transition to Tracy has been smooth.

“I mean, honestly, it feels like he’s been here the whole time,” said Mayer, who played for Tracy at the end of 2024 and beginning of 2025. “I’m sure it’s been a lot for him and he’s been super busy, but he’s been super pro, and I think the players like him. I know the players that have played with him in Triple A love him. He’s one of my favorite managers I’ve ever had. And just playing for him in Triple A was super fun. It was a great experience. And for him to be in the big leagues now. Like, I couldn’t be happier for him. I know he’s more than capable for the job, and he’s such a smart dude, such a smart baseball mind. And I think we’re lucky to have him here.”

Zack Kelly, who’s known Tracy since he was in the Los Angeles Angels’ minor-league system where Tracy was a coach and manager, has seen the same level-headed coach he’s known for years.

“To me, it seems like he’s been the same guy,” Kelly said. “I feel like he came in and kind of didn’t try to do too much, but also at the same time made the message very clear, like, we’re here to win. We’re all in this together. The goal is the exact same. So, very seamless in my opinion.”
