So many teams have made moves toward contending in 2025. But which clubs have done the most?

Let’s take a look at the teams that have changed the most since last season -- whether for better or for worse. Using FanGraphs depth charts projections through March 5, we calculated what percentage of each club’s 2025 plate appearances (for hitters) and batters faced (for pitchers) will go to players who did not appear for that team in 2024 (represented as "turnover rate" below).

Here are 10 teams with contending hopes who experienced plenty of roster turnover this offseason.

Angels (36.5% turnover rate)
Newcomers with most projected PA/BF: Yusei Kikuchi (711), Jorge Soler (574), Kyle Hendricks (556), Yoan Moncada (518), Christian Moore (280)
Departures with most 2024 PA/BF: Griffin Canning (739), Patrick Sandoval (353), Kevin Pillar (282), Matt Moore (210), Luis García (182)

The Angels made plenty of moves this offseason in hopes of returning to the postseason for the first time since 2014, and they didn’t waste any time. Just one day after the end of the 2024 World Series, they sent Griffin Canning -- one of two pitchers to make 30+ starts for the Halos -- to the Braves for Jorge Soler. They stayed aggressive by inking Yusei Kikuchi to a three-year deal a few weeks later, and if 2024 first-round Draft pick Christian Moore makes the Opening Day roster (a distinct possibility), the Angels will look even more different in 2025.

Red Sox (35.6% turnover rate)
Newcomers with most projected PA/BF: Alex Bregman (679), Walker Buehler (641), Garrett Crochet (639), Lucas Giolito (587), Roman Anthony (357)
Departures with most 2024 PA/BF: Nick Pivetta (595), Tyler O’Neill (473), Dominic Smith (278), Chase Anderson (224), Kenley Jansen (218)

Boston has beefed up both its rotation and its lineup for 2025. The Red Sox swung a major trade with the White Sox for flamethrowing lefty Garrett Crochet, and free-agent starter Walker Buehler is expected to face even more hitters than Crochet is. With Lucas Giolito back from UCL surgery (although he’s facing a Spring Training hamstring injury), the Red Sox rotation has been considerably revamped this year. Boston also landed a big bat in Alex Bregman and could promote MLB Pipeline’s No. 2 overall prospect, Roman Anthony, sometime this year.

Cubs (34.5% turnover rate)
Newcomers with most projected PA/BF: Kyle Tucker (665), Colin Rea (522), Matt Shaw (518), Matthew Boyd (510), Justin Turner (357)
Departures with most 2024 PA/BF: Cody Bellinger (569), Kyle Hendricks (567), Christopher Morel (421), Mike Tauchman (350), Drew Smyly (257)

A pair of big trades with the Astros will give the Cubs a new look this season. Deal No. 1, the blockbuster sending Kyle Tucker to Chicago for a three-player package, gives the North Siders a star hitter to build around -- especially if they can secure a contract extension for him. The Cubs also acquired reliever Ryan Pressly from Houston, signed free-agent pitchers Colin Rea and Matthew Boyd and are set to bring their top prospect, Matt Shaw, to Japan for the Tokyo Series.

Dodgers (32.5% turnover rate)
Newcomers with most projected PA/BF: Blake Snell (666), Roki Sasaki (548), Shohei Ohtani (as a pitcher -- 503), Michael Conforto (497), Tony Gonsolin (418), Hyeseong Kim (392)
Departures with most 2024 PA/BF: Gavin Lux (487), James Paxton (390), Walker Buehler (344), Ryan Yarbrough (281), Daniel Hudson (253)

What a rotation the Dodgers could field in 2025. With the additions of Blake Snell and Roki Sasaki to an already talented starting pitching corps, L.A.’s rotation will be perhaps the best in the Majors -- even after Buehler’s departure for the Red Sox. That’s especially true once Shohei Ohtani returns as a pitcher after his dominant 2024 at the plate. The defending World Series champions also added outfielder Michael Conforto and infielder Hyeseong Kim in free agency while trading Gavin Lux to Cincinnati.

Reds (31.1% turnover rate)
Newcomers with most projected PA/BF: Brady Singer (717), Matt McLain (595), Austin Hays (511), Gavin Lux (490), Taylor Rogers (269)
Departures with most 2024 PA/BF: Jonathan India (637), Frankie Montas (411), Buck Farmer (299), Fernando Cruz (288), Justin Wilson (209)

Speaking of Lux, the former Dodger will be a big part of a talented Cincinnati infield that also returns Matt McLain from a shoulder injury that cost him all of 2024. The Reds traded away Jonathan India to the Royals for right-hander Brady Singer, who will immediately slot in behind Hunter Greene at the top of the rotation. Additions like Austin Hays, Taylor Rogers and Jose Trevino mean the Reds will have plenty of new faces in 2025. They’ll be without Frankie Montas (Mets), Buck Farmer (Braves), Fernando Cruz (Yankees) and other key pitchers, though.

Astros (30.5% turnover rate)
Newcomers with most projected PA/BF: Christian Walker (651), Isaac Paredes (609), Luis Garcia (505), Hayden Wesneski (449), Lance McCullers Jr. (390)
Departures with most 2024 PA/BF: Alex Bregman (634), Justin Verlander (396), Kyle Tucker (339), Ryan Pressly (244), Yusei Kikuchi (239)

It’s been a while since the Astros looked this different. Familiar faces like Bregman, Tucker, Pressly and Justin Verlander are all wearing new uniforms in 2025, although Houston has some reinforcements on the way. Acquired from the Cubs for Tucker, Wesneski joins Luis Garcia and Lance McCullers Jr. -- who both missed all of 2024 with injuries -- in the rotation mix, while the free-agent addition of first baseman Christian Walker will bolster one of Houston’s weakest positions last season.

Athletics (29.9% turnover rate)
Newcomers with most projected PA/BF: Luis Severino (755), Jeffrey Springs (554), Gio Urshela (385), Luis Urías (336), Gunnar Hoglund (291)
Departures with most 2024 PA/BF: Ross Stripling (381), Abraham Toro (364), Tyler Nevin (278), Joe Boyle (226), Paul Blackburn (208)

With Brent Rooker and Lawrence Butler seeming like anchors of the team’s offensive future, the A’s made moves this offseason to shape up their rotation. They handed Luis Severino the largest guaranteed deal in franchise history, then acquired lefty Jeffrey Springs in a trade with the Rays two weeks later. Factor in the additions of relievers José Leclerc and Dylan Floro to a bullpen led by All-Star closer Mason Miller, and the A’s could be a surprise contender in 2025.

Yankees (29.6% turnover rate)
Newcomers with most projected PA/BF: Max Fried (722), Paul Goldschmidt (637), Cody Bellinger (602), Fernando Cruz (259), Devin Williams (257)
Departures with most 2024 PA/BF: Juan Soto (713), Nestor Cortes (710), Gleyber Torres (665), Alex Verdugo (621), Anthony Rizzo (375)

The devastating announcement of Tommy John surgery for Gerrit Cole, who faced 390 batters in 2024, certainly muddles the picture for the defending American League champs. But even with Cole’s absence, New York still made a ton of major offseason moves in order to compete in 2025. The Yankees signed lefty starter Max Fried and veteran first baseman Paul Goldschmidt and acquired several key pieces via trade, including a deal for closer Devin Williams and another for outfielder Cody Bellinger. They’ll have to win in a different way without Cole (or Soto) on the roster, but they have the pieces in place to do so.

Mets (29.2% turnover rate)
Newcomers with most projected PA/BF: Clay Holmes (712), Juan Soto (686), Frankie Montas (439), Griffin Canning (420), Jose Siri (413)
Departures with most 2024 PA/BF: Luis Severino (761), Jose Quintana (717), J.D. Martinez (495), Harrison Bader (437), Adrian Houser (309)

Welcome to Queens, Juan Soto. The superstar outfielder is projected to co-lead the Mets (along with Francisco Lindor) in plate appearances, with Jose Siri taking Harrison Bader’s roster spot as a glove-first center fielder but few other changes to the offense, save J.D. Martinez’s departure in free agency. There’s plenty of churn on the pitching side, though, with Severino off to the A’s and pitchers like Clay Holmes and Montas joining the squad. Injuries to Montas and Sean Manaea could put a damper on things, but the Mets have pitching depth with Canning, Tylor Megill, Paul Blackburn and others.

Blue Jays (24.4% turnover rate)
Newcomers with most projected PA/BF: Anthony Santander (672), Andrés Giménez (637), Max Scherzer (500), Jeff Hoffman (263), Nick Sandlin (249)
Departures with most 2024 PA/BF: Yusei Kikuchi (497), Spencer Horwitz (381), Justin Turner (349), Isiah Kiner-Falefa (281), Génesis Cabrera (271)

It’s officially a walk year for Vladimir Guerrero Jr., so contending in 2025 is even more important for a Blue Jays team fortified with veterans. Among other moves, Toronto traded for Andrés Giménez, added Max Scherzer to its rotation and brought in slugger Anthony Santander for its outfield. The Blue Jays will miss Kikuchi, who was a reliable arm before being dealt to Houston during the 2024 season, and they also had to deal away a promising bat in Spencer Horwitz to get Giménez from Cleveland. But it seems like the year to take big swings, and Toronto has done that.
