While he’s never been a true liability on the infield, Max Muncy has generally been a player whose defensive contributions took a back seat to his offense. The Dodgers have long counted on Muncy’s combination of power and plate discipline to outweigh his shortcomings in the field while bouncing him from first base to second to third depending on their roster’s current needs. That handling has paid off handsomely, as he’s been a vital contributor to four pennant winners and three World Series champions since being plucked off the scrap heap in April 2017. This year, however, Muncy has really flashed the leather at third base, showing the best range of his career. He leads all third basemen in Statcast’s Fielding Run Value, while tying for second in Defensive Runs Saved.

According to Statcast, Muncy was 11 runs below average at third base in 3,817 innings from 2018–25, roughly the equivalent of four runs below average per full season of play; he was four below average by that measure in just 801.1 innings last year. This year, he’s already six runs above average in 621 innings. According to Statcast’s Outs Above Average, he’s gone from being the majors’ worst qualifier on plays coming in (-9) to tying for second-best (4). DRS has generally been more charitable in its assessment of his defense; he was 16 runs above average at third from 2018–25, and is eight above average this season.

Muncy is just one of several Dodgers whose defensive play has helped his team top the rankings in my annual midseason defensive breakdown, with shortstop Mookie Betts, center fielder Andy Pages, second baseman Alex Freeland, and catcher Will Smith also making major contributions to that placement. I’ll explain the methodology below, but first, a bit more about the 35-year-old slugger, who on Monday night hit a towering solo homer in the first Dodgers-Athletics matchup to feature both Max Muncys, who share the same birthday (August 25) and drafting team (Oakland).

Woo-Suk Go was one of Korea’s top closers from 2019-2023. Over that five-season span, the 27-year-old right-hander logged 137 saves and a 2.39 ERA across 275-and-a-third innings with the LG Twins. Moreover, his 29.3% strikeout rate was the highest among KBO hurlers who threw at least 200 frames.

He hasn’t had nearly as much success since coming stateside. Signed as an international free agent by the San Diego Padres in January 2024, Woo-Suk was subsequently swapped to the Miami Marlins four months later in the Luis Arraez deal, only to be released in June 2025 and picked up by the Detroit Tigers. His inability to gain a foothold is reflected in the numbers. He entered the current campaign having recorded just six saves and a 5.61 ERA over 75 appearances down on the farm.

This season has been an another story. Looking more like the pitcher who dominated KBO hitters, Woo-Suk boasts a 2.06 ERA, a 2.26 FIP, and a 35.1% strikeout rate over 39-and-a-third innings across 25 appearances, eight with Double-A Erie and 17 with Triple-A Toledo. Working most often in a setup role, he is 3-1 with three saves.

Results aside, how does he differ from the young pitcher who excelled in his homeland? Read the rest of this entry »

Monday marked the one-year anniversary of the blockbuster trade that sent Rafael Devers from the Red Sox to the Giants in exchange for a four-player package. Neither team marked the occasion by throwing a party; mercifully, both were idle, and so didn’t sink further below .500. The deal hasn’t worked out well for either side, though it’s the Giants with an expensive and apparently declining slugger on the books. While Devers was fairly productive after being dealt last season, so far in 2026, the 29-year-old first baseman has surrounded one very good month (May) with a pair of miserable slumps that are just part of the reason the Giants are buried in the NL West standings.

We’ve told and re-told the story of the drama in Boston that led up to the Devers trade, but the streamlined version is that the signing of third baseman Alex Bregman bumped Devers off his natural position. After that, a lack of communication between the front office and the slugger — whose defense at the hot corner had eroded — exacerbated the team’s attempts to slot him first at designated hitter and then, after Triston Casas was injured, at first base, a position he had never played before and was reluctant to begin learning in-season. On June 15, 2025, the Red Sox sent Devers to the Giants for lefty Kyle Harrison, righties Jose Bello and Jordan Hicks, and outfielder James Tibbs III, with the Giants assuming the roughly $254 million remaining on Devers’ 10-year, $313.5 million contract, which runs though 2033.

The Red Sox were just 36-36 at the time of the trade, the Giants 41-30. Over the remainder of the season, the two teams’ fortunes reversed, with Boston going 53-37 and securing a Wild Card berth, just the team’s second trip to the postseason since winning the World Series in 2018, and San Francisco going 40-51 and missing the playoffs for the eighth time in nine seasons. Each team has changed managers since, with the Giants axing Bob Melvin in favor of Tony Vitello — the rare manager to make the jump directly from the college coaching ranks — last October and the Red Sox firing Alex Cora in late April. Those varying paths have led the two teams to similar spots: the Red Sox are 29-41, last in the AL East, while the Giants are 29-43, two games out of last place in the NL West. (Note that throughout this piece, stats from our site include those from Devers’ two plate appearances in Tuesday night’s suspended game against the Braves, while those from Baseball Savant do not.)

Erik Tolman has a remarkable backstory. Currently playing for the Triple-A Rochester Red Wings, the 26-year-old left-hander threw to one of baseball’s most prolific pitchers as a prep, and that is a comparatively insignificant part of his past. His level of perseverance is nothing short of remarkable. Tolman has overcome debilitating injuries on his journey to the doorstep of the big leagues.

His travails began in 2021, the year the Washington Nationals drafted him in the 14th round out of Arizona State University. He had the first of two Tommy John surgeries, costing him all but three games in his final collegiate campaign — and his bad fortune was only just beginning.

“I tore my UCL again at the end of my rehab,” Tolman explained. “Fourteen months after having surgery, in my last live ABs, I felt my elbow go again. It was a sad moment, honestly. But I talked to my family, and I believed in myself — I thought I could still be a big-leaguer — so I kept at it. Unfortunately, on my fifth start back, in August 2023, I dislocated my knee. That made for a whole new mountain that I’ve had to climb.

“The injuries have driven me to have a work ethic, and a mental fortitude, of just going balls to the wall,” he added. “I figured I could either struggle coming back from the injuries, playing baseball, or struggle out in the real world. At the end of the day, we’re the ones responsible for our lives and careers. If you get hurt, are you going to cave, or are you going to overcome?”

Tolman did far more than simply dislocate a knee after returning from the second TJ. What happened was not only catastrophic: it was hard to fathom. Read the rest of this entry »

Below is an analysis of the prospects in the farm system of the Boston Red Sox. Scouting reports were compiled with information provided by industry sources as well as our own observations. This is the sixth year we’re delineating between two anticipated relief roles, the abbreviations for which you’ll see in the “position” column below: MIRP for multi-inning relief pitchers, and SIRP for single-inning relief pitchers. The ETAs listed generally correspond to the year a player has to be added to the 40-man roster to avoid being made eligible for the Rule 5 draft. Manual adjustments are made where they seem appropriate, but we use that as a rule of thumb.

A quick overview of what FV (Future Value) means can be found here. A much deeper overview can be found here.

All of the ranked prospects below also appear on The Board, a resource the site offers featuring sortable scouting information for every organization. It has more details (and updated TrackMan data from various sources) than this article and integrates every team’s list so readers can compare prospects across farm systems. It can be found here.

Tyler Samaniego isn’t perfect anymore. After throwing 15 scoreless innings over his first 13 big league appearances, the left-hander was taken deep by Kyle Schwarber with a runner aboard in the eighth inning this past Thursday night as the Boston Red Sox fell to the Philadelphia Phillies, 3-1. The inevitable imperfection was followed by a double whammy. On Friday, Samaniego surrendered a 10th-inning walk-off two-bagger to Mike Yastrzemski — the only batter he faced — in a 3-2 loss to the Atlanta Braves. Flawless no more, he now has a still-stellar 1.17 ERA and a pair of losses over his first 15 outings.

His initial level of success was somewhat surprising, and the same could be said of the 27-year-old rookie having earned an opportunity to show his mettle in high-leverage situations. He was anything but a proven commodity at season’s start. As for his presence in the Red Sox bullpen, that wasn’t wholly unexpected. When he came to Boston as part of the five-player December deal that shipped “The Password” to the Pirates, Eric Longenhagen wrote that Samaniego was “fairly likely to play a role on Boston’s pitching staff in 2026… occupying a lefty specialist spot.”

Shortly before he suffered his first big league adversity, I approached the 2021 15th-round pick out of the University of South Alabama to learn more about him. I’d perused his stat sheet, seen him pitch a handful of times, and knew that he had undergone an internal brace procedure while in the minors, but that was about it. As such, I began by asking how he has progressed as a pitcher over the years. Read the rest of this entry »

Things could be going better for Brayan Bello. I guess that’s true of most Red Sox players these days, but the right-hander is having an especially rough go of things. On Sunday, Bello took the decision in an 8-1 loss to the Braves, allowing seven earned runs in five innings pitched.

That kind of line doesn’t necessarily signal a terrible outing; sometimes a starter trudges along in quality-start territory before running into trouble late. A couple quick walks, then the bullpen lets a couple inherited runners score… three runs allowed over four innings can turn into seven runs in five innings in a flash.

That wasn’t the case here. Seven of the first 10 Braves hitters reached base; five of them scored. Manager Chad Tracy let Bello wear it until he’d reached five innings and 98 pitches. And it was Bello’s 27th birthday on Sunday, too. Usually you only hear “wear it” on a guy’s birthday in the context of a party hat or a new shirt. Read the rest of this entry »

Kai-Wei Teng had a limited repertoire when he signed with the Minnesota Twins out of Taiwan in 2017. The right-hander from Taichung possessed just a fastball and a curveball. A lot has changed since that time. Now 27 years old and pitching for the Houston Astros, Teng attacks hitters with a five-pitch mix that includes a sweeper that is not only hard to hit, it is no fun to be on the receiving end of in catch-play.

“It’s insanely good,” Spencer Arrighetti told me last weekend at Fenway Park. “I throw a sweeper. Lance [McCullers] throws a sweeper. We have a couple of other guys who toy around with it. But Teng’s is incredible. Truly. I played catch with him, and it looks like a fastball for 48 feet, then takes a 90-degree left turn. Not all sweepers are created equal. Some of them are a little loopier and bigger, but his is 85 mph. I mean, it’s gross. It really is a great pitch.”

The numbers back that up. Teng has relied on his most-used offering 36.3% of the time this season to the tune of a .118 BAA, a .118 SLG, and a 27.9% whiff rate. His other numbers are impressive, as well. Over 14 appearances, Teng has a 2.35 ERA, a 3.83 FIP, and a 24.7% strikeout rate over 23 innings.

I asked Teng for the story behind his best weapon. Read the rest of this entry »

The best team in baseball will be without its biggest star for a few weeks.

The Braves placed Ronald Acuña Jr. on the injured list Sunday with a strained left hamstring. Acuña exited Saturday’s game after pulling up in considerable pain while running out a groundout. Manager Walt Weiss told reporters that imaging revealed a Grade 1 strain, the least severe grade. According to MLB.com, Weiss said:

“It’s not going to be just a couple days. It’s gonna be more than that, so we need to put him on the IL, and hopefully it’ll be sooner than later. No idea with these soft tissue injuries how long they’re gonna take, but I think the silver lining is that the MRI showed it wasn’t too serious.”

While many players return from Grade 1 hamstring strains in just a couple weeks, or even following the 10-day minimum, this is an injury that can linger and delay a return.

This is, obviously, less than ideal for the Braves. Acuña is their best player and was projected in the preseason as the ninth-best position player in baseball with 5.4 WAR, according to our Depth Charts. Though his performance hasn’t been spectacular thus far, with a 111 wRC+ in 152 plate appearances, his .381 xwOBA and 12.2% barrel rate — along with strong strikeout and walk rates — suggest he hasn’t missed a beat this year, coming off his bounce-back 2025 season.

Of course, last year was a comeback campaign because Acuña missed most 2024 (and the early part of 2025) after tearing his ACL. He also missed chunks of 2021 and 2022 with a torn ACL in his other knee. In 2018, he missed about a month with a mild ACL sprain. That means Acuña’s hamstring strain is his fourth lower body injury requiring IL time in his career. Read the rest of this entry »
