The World Series is an exclusive event, but that doesn't mean that fans of the 28 clubs that didn't make it here won't have a chance to see a familiar face (or seven, as the case may be) in this year's Fall Classic.

Long since traded prospects and old friends abound. Based on current rosters (with one notable exception) and counting only Major League appearances, here's how all 30 teams are represented in the 2023 World Series.

Yankees: 7
Nathan Eovaldi (2015-16), Jace Peterson (2018), Joe Mantiply (2019), Andrew Heaney (2021), Miguel Castro (2022), Aroldis Chapman (2016-22), Jordan Montgomery (2017-22)

Believe it or not, Mantiply, now an indispensable member of the D-backs bullpen, earned his first Major League win in his sole appearance as a Yankee in 2019.

Mets: 6
Paul Sewald (2017-20), Miguel Castro (2021), Jacob deGrom* (2014-22), Travis Jankowski (2022), Max Scherzer (2022-23), Tommy Pham (2023)

While deGrom won't appear in this Series, it's difficult to leave off such an icon of Mets baseball from a list such as this. Four of his former Mets teammates are, however, likely to see action.

Dodgers: 5
Nathan Eovaldi (2011-12), Josh Sborz (2019-20), Corey Seager (2015-21), Max Scherzer (2021), Andrew Heaney (2022)

Eovaldi's long and winding Major League career started in Los Angeles, where he was an 11th-round pick in 2008. He was later dealt to the Marlins in the Hanley Ramirez trade alongside current D-backs reliever Scott McGough. Unfortunately for this list, McGough, sidelined with right shoulder inflammation, won't be taking the mound again this year.

Rays: 5
Evan Longoria (2008-17), Nathan Eovaldi (2018), Tommy Pham (2018-19), Nathaniel Lowe (2019-20), Ryan Thompson (2020-23)

Longoria's incredible career in Tampa Bay began, appropriately, with a championship bid, but he hadn't made it back to baseball's biggest stage until now. His third-inning single against Eovaldi in Game 1, his second career World Series hit, came 15 years to the day after his first in Game 5 of the 2008 World Series against the Phillies -- the longest gap between World Series hits in MLB history.

A's: 4
Marcus Semien (2015-20), Robbie Grossman (2019-20), Jonah Heim (2020), Jace Peterson (2023)

Heim was actually drafted in 2013 by the Orioles, but he made his debut with Oakland in 2020, appearing in 13 games after he was acquired from the Rays in exchange for Joey Wendle.

Blue Jays: 4
Miguel Castro (2015), Lourdes Gurriel Jr. (2018-22), Marcus Semien (2021), Gabriel Moreno (2022)

Less than a year ago, Moreno was Toronto's No. 1 prospect. The December 2022 trade that brought him to Arizona also netted Gurriel for the D-backs in exchange for Daulton Varsho.

Cardinals: 4
Tommy Pham (2014-18), Adolis García (2018), Chris Stratton (2022-23), Jordan Montgomery (2022-23)

Well before his ascension to his current role as an icon of postseason baseball, García played in 21 games for the 2018 Cardinals, going 2-for-17 with a double and an RBI.

Padres: 4
Jace Peterson (2014), Travis Jankowski (2015-19), Austin Hedges (2015-20), Tommy Pham (2020-21)

Hedges was the Padres' top prospect for a time and served as their primary catcher from 2017 until he was traded to Cleveland in 2020.

Braves: 3
Jace Peterson (2015-17), Will Smith (2020-22), Robbie Grossman (2022)

The well-traveled Peterson had his longest stint in Atlanta, but most notable now is how he ended up there -- he was one of the four Padres Minor Leaguers sent to the Braves as part of the then-massive Justin Upton deal in December 2014.

Giants: 3
Chris Stratton (2016-18), Will Smith (2016-19), Evan Longoria (2018-22)

Stratton was a first-round pick by the Giants in 2012 and was the club's No. 3 prospect as ranked by MLB Pipeline in 2013, although his time in San Francisco was pretty brief.

Mariners: 3
Ketel Marte (2015-16), Travis Jankowski (2022), Paul Sewald (2021-23)

Marte was once a minor piece in a big trade -- he came to Arizona along with Taijuan Walker in exchange for Mitch Haniger, Jean Segura and Zac Curtis in 2016.

Marlins: 3
Nathan Eovaldi (2012-14), Andrew Heaney (2014), Zac Gallen (2019)

Gallen made just seven starts at the beginning of his career in Miami, pitching to a sparkling 2.72 ERA before being swapped to the D-backs in exchange for another young talent -- Jazz Chisholm Jr. -- at the 2019 Deadline.

Reds: 3
Aroldis Chapman (2010-15), Travis Jankowski (2020), Tommy Pham (2022)

Chapman almost instantly attained top prospect status upon his defection from Cuba in 2009. He signed with the Reds in January 2010 and made four All-Star teams in Cincinnati before he was traded to the Yankees in 2015.

Royals: 3
Will Smith (2012-13), Emmanuel Rivera (2021-22), Aroldis Chapman (2023)

Smith's career began in Kansas City, where he debuted as a 22-year-old starting pitcher in 2012.

Tigers: 3
Max Scherzer (2010-14), Joe Mantiply (2016), Robbie Grossman (2021-22)

In the Tigers' overpowering starting rotation of the early 2010s, Scherzer flew under the radar. Even so, he won the first of his three Cy Young Awards in Detroit in 2013.

Orioles: 3
Christian Walker (2014-15), Jace Peterson (2018-19), Miguel Castro (2017-20)

You may not remember Walker's time in Baltimore -- although MLB Pipeline ranked him as high as No. 3 in the Orioles' system in 2015 (a year in which Dylan Bundy led the pack), he played just 13 games in an Orioles uniform.

Red Sox: 3
Martín Pérez (2020-21), Nathan Eovaldi (2018-22), Tommy Pham (2022)

Eovaldi's postseason heroics originated in Boston, where he was the workhorse behind the Red Sox's 2018 World Series run -- you may remember his iconic six-inning relief appearance in Game 3 of the World Series.

Twins: 3
Robbie Grossman (2016-18), Martín Pérez (2019), Mitch Garver (2017-21)

Pérez's time away from Texas was relatively brief, but when his Rangers career first appeared over, he initially traveled north to Minnesota.

Angels: 2
Chris Stratton (2019), Andrew Heaney (2015-21)

Heaney, way back in 2014, was traded twice in one day, first from the Marlins to the Dodgers, then to the Angels, where he immediately became L.A.'s top-ranked prospect by MLB Pipeline.

Astros: 2
Robbie Grossman (2013-15), Will Smith (2022)

Grossman, originally drafted by the Pirates in 2008, debuted in Houston, but was on his way out just before the franchise saw its full revival.

Brewers: 2
Will Smith (2014-16), Jace Peterson (2020-22)

After a swap to Milwaukee in exchange for outfielder Nori Aoki, Smith's career really took off. The Brewers kept him in the bullpen, and in his first season there, he led the National League with 78 appearances.

Guardians: 2
Kyle Nelson (2020-21), Austin Hedges (2020-22)

Nelson was drafted by Cleveland in 2017 and made his debut with one (rough) appearance in 2020. The D-backs selected him off waivers in November 2021.

Pirates: 2
Chris Stratton (2019-22), Austin Hedges (2023)

Pittsburgh was where Stratton began his transformation into an effective full-time reliever -- and after two consecutive seasons in which he was included in a Deadline deal, it's almost hard to believe the Pirates only had to purchase him.

Rockies: 2
Miguel Castro (2015-16), Jon Gray (2015-2021)

Gray was the third overall pick in the 2013 Draft, and while things didn't necessarily pan out the way the Rockies may have hoped for his time in Colorado, he is in the World Series now. Not too bad.

White Sox: 2
Marcus Semien (2013-14), Dane Dunning (2020)

We've spent the most time talking about Lucas Giolito and Reynaldo López, but the Nationals actually sent three prospects to Chicago in exchange for Adam Eaton in 2016 -- Dunning was the third.

Cubs: 1
Aroldis Chapman (2016)

Chapman's time in Chicago was brief but historically relevant: He was credited with the win in Game 7 of the 2016 World Series.

Nationals: 1
Scherzer (2015-21)

If Scherzer somehow went unnoticed in Detroit, he became the main attraction in Washington, where he won two more Cy Youngs and his first World Series ring.

Phillies: 1
Jankowski (2021)

The only crossover in this year's NLCS, Jankowski played in 76 games for the 2021 Phillies.

D-backs: Max Scherzer (2008-09)
It's only fair that we make mention of the only player on either World Series roster to have played for the opposing team. Scherzer's time in Arizona was brief, but it was where his remarkable career started, and where he, along with current teammate Ian Kennedy, would end up in a then-huge three-team deal that sent Curtis Granderson to the Yankees.
