Few players were identified more strongly with a single team in the 2010s than Madison Bumgarner with the Giants.

After a brief debut at the end of 2009 that included one start, the left-hander was a staple in the San Francisco rotation throughout the next decade. He started 285 more games for the Giants in that time, won 119, made four All-Star teams, and most importantly, became an October legend who played a key role in the club’s World Series championships in 2010, ‘12 and ‘14.

On Saturday night, Bumgarner will again take the mound at Oracle Park. But this time, he will do so in a D-backs uniform, after signing a five-year contract with Arizona this past offseason. It will be a strange sight, to be sure, but this sort of situation is not unprecedented.

In the Wild Card Era (since 1995), there have been 11 other pitchers who have made at least 250 starts for a team and then started against that team during the season they departed, or in the following season. This doesn’t include pitchers who faced their former team in a later season, such as Mark Buehrle, who left the White Sox after 2011 and didn’t face them until ‘13.

The games below are listed in reverse chronological order, and only the pitcher’s first matchup against the team is noted.

Justin Verlander (Astros) vs. Tigers
July 15, 2018: 6 IP, 6 H, 6 R, 5 ER, 0 BB, 12 K (loss)
Verlander ranked fourth in Tigers history in starts (380) when the team completed a last-minute trade to send him to Houston before the Aug. 31 Deadline in 2017. JV went on to up his game for the Astros, winning a World Series title that fall and his second American League Cy Young Award in ‘19. His first encounter against Detroit was an odd one, as Verlander struck out 12 batters without issuing a walk but also served up a season-high four homers at Minute Maid Park.

Bronson Arroyo (D-backs) vs. Reds
May 30, 2014: 7 IP, 9 H, 5 R, 5 ER, 1 BB, 3 K (loss)
Acquired from Boston before the 2006 season, Arroyo immediately became an All-Star in Cincy, making at least 32 starts in eight consecutive seasons even as his effectiveness fluctuated. After a solid 2013 for the Reds (202 innings 3.79 ERA), the 37-year-old soft-tossing righty signed with Arizona for a stint that listed just 14 games before injuries intervened. Arroyo returned to the Majors briefly with Cincinnati in 2017, making 14 more starts.

Roy Oswalt (Phillies) vs. Astros
April 3, 2011: 6 IP, 5 H, 2 R, 2 ER, 1 BB, 6 K (win)
Oswalt made nearly 300 starts for the Astros from 2001-10, with two 20-win seasons, three All-Star selections and five top-five Cy Young Award finishes. But before the 2010 Trade Deadline, the Astros flipped him to postseason-bound Philadelphia in a deal that included J.A. Happ and Jonathan Villar. The following season, Oswalt was part of a super-rotation with Roy Halladay, Cliff Lee and Cole Hamels, and his first start came against his old club.

Roy Halladay (Phillies) vs. Blue Jays
June 25, 2010: 7 IP, 6 H, 0 R, 1 BB, 4 K (win)
Halladay is second in Blue Jays history in WAR behind only Dave Stieb, having been drafted with the 17th overall pick in 1995 and spending 12 seasons in Toronto before a December 2009 trade that set up his long-awaited first taste of playoff baseball. Not surprisingly, the stoic “Doc” was the same pitcher against the Blue Jays as he had been for them for so many years, shutting down his former team. "I did the best I could to take emotions out of it and go out and pitch," he said afterward.

Tom Glavine (Mets) at Braves
May 24, 2003: 3 1/3 IP, 8 H, 6 R, 6 ER, 2 BB, 0 K (loss)
Glavine made a whopping 505 starts for Atlanta prior to signing with the Mets in December 2002 -- easily the highest total for anyone on this list. The lefty was a two-time Cy Young Award winner with the Braves before his free-agent defection, which he called “surreal,” adding, “I never thought I would play for someone else.” Yet the 37-year-old found himself with a division rival. His first encounter with his old teammates went poorly, and Glavine posted a 5.15 ERA against the Braves in five seasons with the Mets -- including 10.35 in 2003 -- before returning to Atlanta for a last hurrah in ‘08.

Greg Maddux (Cubs) vs. Braves
Oct. 3, 2004: 6 IP, 7 H, 6 R, 6 ER, 1 BB, 4 K (win)
Maddux was a Cub before he was a Brave, but made far more starts with Atlanta (363) than in his first stint in Chicago (208). He returned to his original team as a free agent prior to the 2004 season but it wasn’t until his final outing that year that he finally met the Braves on the mound for the first time since 1992. It was hardly Maddux’s best performance, but he still came out with one of his 355 career victories -- not that it took the sting out of Atlanta making yet another postseason appearance while Maddux’s Cubs fell just short.

Kevin Appier (A’s) at Royals
June 17, 2000: 7 IP, 7 H, 4 R, 4 ER, 2 BB, 1 K (win)
Appier remains the Royals’ all-time leader in pitching WAR and strikeouts, accruing most of those stats in his first stint with the franchise, from 1989-99. Kansas City dealt him to Oakland at the 1999 Trade Deadline, and a bit less than a year later, Appier faced his original club in back-to-back starts. Both were victories, with Oakland giving 10 runs of support in both games to overcome his nine runs allowed. Appier eventually returned to the Royals for his final six career starts in 2003-04.

Mike Mussina (Yankees) at Orioles
May 6, 2001: 7 IP, 6 H, 1 R, 1 ER, 2 BB, 3 K (win)
There was a bit of tension that day at Camden Yards. Not only had Mussina left the Orioles as a free agent -- he had gone to the dark side, signing a big-money contract with the hated Yankees. While many Baltimore fans welcomed back their five-time All-Star, others harbored some hard feelings. One held up a sign reading “Mussina is a sellout.” None of that stopped Moose from authoring a typically stellar performance, although he went on to post just a 4.83 career ERA against Baltimore. In the end, the righty didn’t didn’t pick a side, going into the Hall of Fame bearing a blank cap on his plaque in 2019.

Chuck Finley (Indians) vs. Angels
May 31, 2000: 6.2 IP, 9 H, 3 R, 2 ER, 3 BB, 8 K (win)
Finley is the Angels’ all-time leader in starts (379) as well as several other categories, having pitched 14 seasons in Anaheim. A free agent after the 1999 campaign, he signed with Cleveland, and upon his return to his old ballpark said, “It will be strange to be in this dugout and look over there and see buddies.” Finley went on to win 16 games for the Indians, including this one, and put together his fifth All-Star season.

Randy Johnson (D-backs) at Mariners
July 20, 1999: 9 IP, 8 H, 0 R, 0 BB, 10 K (win)
That the Big Unit threw the first shutout in the history of what was then called Safeco Field seemed only right. That the left-hander didn’t do so in a Mariners uniform was the strange part. Johnson became the game’s most feared pitcher in Seattle, but at the 1998 Trade Deadline, he was shipped to Houston. That offseason, he signed with the D-backs and proceeded to win four consecutive NL Cy Young Awards.

Roger Clemens (Blue Jays) at Red Sox
July 12, 1997: 8 IP, 4 H, 1 R, 1 ER, 0 BB, 16 K (win)
The Rocket is probably remembered most as a member of the Red Sox or Yankees, or maybe even late in his career with the Astros. But his best season may have come in 1997 after Boston let him leave for Toronto as a free agent. It took until halfway through that season for Clemens to get a shot at his former team, and he responded with 16 K’s at Fenway Park. “He came to make a point,” said Boston’s Mo Vaughn. “And he did.”
