When determining which team to root for this postseason, the general rule of thumb is to root against the Mets rivals. With the Mets making a number of trades this season, you could also root for teams according to their Mets connections:
East – Boston Red Sox
Assistant Pitching Coach – Brian Bannister (2006)
Bannister made the Mets out of Spring Training in 2006. His tenure was short lived as he injured his hamstring, and Omar Minaya rebuilt the rotation in-season pushing a healthy Bannister out. He’d ultimately be moved that offseason in an ill-fated trade for Ambiorix Burgos.
RHP Blaine Boyer (2011)
Boyer pitched just five games for the Mets before leaving via free agency. He would not pitch in the majors again until 2014.
RHP Addison Reed (2015-17)
Acquired on the eve of September, Reed quickly became an important seventh inning reliever on the Mets pennant winning team. He was even better the next season, helping pitch the Mets back to the postseason. With Jeurys Familia‘s suspension and injury, Reed became an effective closer before being traded for a trio of Red Sox relief prospects at the trade deadline.
OF Chris Young (2014)
After a few down years, the Mets took a one year gamble on Young. He struggled all year and was released with the Mets eight games under .500 and 10.5 games back in the division. Since that time, Young has been a much more effective player.
Central – Cleveland Indians
First Base Coach Sandy Alomar, Jr. (2007-09)
Alomar ended his playing career appearing in eight games with the Mets in 2007. He then began his coaching career with New York serving two years as a special catching instructor.
RF Jay Bruce (2016-17)
Bruce went from bust who struggled mightily after being acquired at the trade deadline last year to fan favorite this year. Fortunately for the Indians, Bruce wouldn’t repeat his struggles helping propel the Indians to 102 wins.
RHP Joe Smith (2007-08)
Smith went straight from being a third round draft pick in 2006 to being a very good reliever for the Mets in two seasons. Ironically, he moved as part the three team J.J. Putz trade intended to improve the Mets bullpen.
West – Houston Astros
DH Carlos Beltran (2005-11)
Seeing him in the postseason again will certainly evoke memories of Adam Wainwright, but he was so much more than that in a Mets uniform. Beltran was arguably the best center fielder in Mets history and perhaps their best outfielder ever.
C Juan Ceteno (2013-14)
Centeno is a strong defensive catcher who played just 14 games over two years before he was claimed off waivers by the Milwaukee Brewers.
Bench Coach Alex Cora (2009-10)
Cora joined the Mets in the hopes of being an important utility player on a playoff caliber team. Unfortunately, injuries and a ballpark ill-suited for the talents of the players on the roster brought that run to an end.
Hitting Coach Dave Hudgens (2011-14)
Hudgens was the Mets hitting coach who was entrusted with helping the team adapt to a new ballpark. While he was much embattled in the position, Mets offensive highlights during his tenure included Ike Davis hitting 30 homers and the last great season from David Wright.
Pitching Coach Brent Strom (1972)
Strom was the Mets 1970 first round draft pick. He appeared in just one season with the team going 0-3 with a 6.82 ERA and a 1.615 WHIP.
Third Base Coach Gary Pettis (2000-04)
Pettis served as the first base and outfield coach during the Art Howe Era.
Wild Card – Minnesota Twins
Pitching Coach Neil Allen (1979-83)
While Allen had a noteworthy Mets career of his own, he will forever be known as one of the two players traded by the Mets in exchange for Keith Hernandez.
RHP Bartolo Colon (2014-16)
Known fondly to Mets fans as “Big Sexy,” Colon became a fan favorite and a mentor to the young pitchers in the clubhouse. There are a number of highlights you can choose from his Mets career, but the one that keeps coming to mind was the unbelievable home run he hit in San Diego last year.
RHP Dillon Gee (2010-15)
Gee is an example of a pitcher who has gotten everything out of his ability. He has been resilient overcoming a number of injuries in his career with his career highlight possibly being named the Mets 2014 Opening Day starter.
East – Washington Nationals
OF Alejandro De Aza (2016)
De Aza had an interesting year with the Mets. He was terrible to begin the year, but had a great July helping propel the Mets second half run to the Wild Card.
Pitching Coach Mike Maddux (1993-94)
Maddux pitched two years for the Mets pitching to a 4.16 ERA as a reliever before departing via free agency.
2B Daniel Murphy (2008-15)
Somehow Murphy has become one of the most divisive players among the Mets fanbase. Many still fondly remember him for his time with the Mets, especially his incredible NLDS and NLCS leading the Mets to the pennant. Others see a player who annihilates the Mets since leaving the team.
LHP Oliver Perez (2006-10)
Believe it or not, there was a time where Perez was beloved for his Game 7 performance and his start the final game of the 2008 season. He then fell off a cliff upon receiving a huge contract. Things got so bad, he refused a minor league assignment and his last appearance as a Met would be the team throwing him into the 14th inning on the last game of the season just to get the game over with.
Central – Cubs
Quality Control Coach Henry Blanco (2010)
“Hank White” was brought on as a defensive back-up, and he excelled in the role throwing out 50 percent of base stealers.
C Rene Rivera (2016-17)
Rivera was a defensive specialist who helped Noah Syndergaard overcome his issues holding base runners. It was more than Syndergaard, Rivera served as a mentor for young starters Seth Lugo and Robert Gsellman who helped pitch the Mets to the Wild Card.
West – Dodgers
Bench Coach Bob Geren (2012-15)
Geren served as the bench coach for the Mets working as a mentor for the Mets catchers. Since his departure, we have seen Mets catchers regress in their pitch framing and we have certainly seen Travis d’Arnaud regress in nearly every aspect of his game.
OF Curtis Granderson (2014-17)
Granderson is one of the finest men to ever put on a Mets uniform. He also came up biggest when the Mets needed him most. Granderson kept the Mets afloat in 2015, and if not for some blown leads, he was in line to be the MVP of that series. His big outburst to end the 2016 season helped lead the Mets back to the postseason.
3B Justin Turner (2010-13)
Turner was an effective utility player in his years with the Mets who was really non-tendered because he was arbitration eligible. Turner would find himself a home in Los Angeles where he has become a terrific player.
Third Base Coach Chris Woodward (2005-06)
Woodward was a valuable utility player for the Mets for two seasons having the second best season of his entire career in 2005.
Wild Card – Diamondbacks
RHP Matt Koch (2012-15)
Koch was one of the two minor league pitchers traded by the Mets for Addison Reed. While Koch is on the 40-man roster, it is not expected he will be on the postseason roster.
Based on the sheer volume of Mets affiliations, it would appear Mets fans would be pulling for the Astros in the American League and either the Nationals or Dodgers in the National League. Considering the presence of Chase Utley on the Dodgers and the recent rivalry with the Nationals, most Mets fans will understandably choose rooting interests for different reasons all together.
