Welcome to my annual preseason Baseball Bits article!
If you were unaware, today marks 5 years since I started my Boston Sports Mania blog! The Red Sox were just about to begin their regular season when I started, and just like this year, they were coming off a World Series victory. On my first day, I posted an article titled “MLB 2014 Preview”, which included my predictions for the 2014 MLB season. I still write these prediction articles every year, including this year.
I call March 25th my “blog-a-versary”, and this year is a big milestone. All of my opportunities are a result of this blog. Most recently, I delivered a motivational keynote speech about my story so far at the Visions of Community Conference hosted by the Federation for Children with Special Needs at the Boston Seaport World Trade Center (see below):
I started this blog to write about my favorite sports like baseball, which is what today’s post is about.

In 2018 the Red Sox became the 16th team in the 162-game era to win over 100 regular season games and then go on to win the World Series. They were led by new manager Alex Cora and a new star in J.D. Martinez. But what most Boston sports fans are wondering about now is how the Red Sox will do in 2019 and whether they will repeat. I did some research on 100+ win World Series winners in the 162-game era and how they did in their next season below.
The Research

The “Baseball Bits”
Note: In the context of this article, a team who repeats for 2 years in a row is counted for 1 repeat, 3 years in a row is counted for 2 repeats, 4 years in a row is counted for 3 repeats, etc
- Only 23 of 115 (20%) World Series winners have repeated
- In the 162-game era, only 16 of 57 (28%) 100-win teams have won the World Series, including the 2018 Red Sox
- In the 162-game era, only 9 of 56 (16%) World Series winners excluding the 2018 Red Sox have repeated, with 4 of the teams repeating after 100-win seasons
- Of the 15 100 win World Series winners excluding the 2018 Red Sox:9 teams (60%) made the playoffs4 teams (26.67% of the 15) repeated2 of those teams reached 100 wins when they repeated:1976 Cincinnati Reds
-
- 1978 New York Yankees
- 2 of those teams failed to reach 100 wins again when they repeated:1962 New York Yankees
-
- 1999 New York Yankees (repeated again in 2000
- The Red Sox did not win the World Series in an 100 win season in the 162-game era until 2018
- Another 2 of the 15 (13.33%) lost the World Series:1968 St. Louis Cardinals
-
- 1978 Baltimore Orioles
- 3 of the 15 (20%) lost in the LCS2010 New York Yankees
-
- 2017 Chicago Cubs
-
- 2018 Houston Astros
- 6 of the 15 (40%) missed the playoffs entirely1969 Detroit Tigers
-
- 1970 New York Mets
-
- 1977 Cincinnati Reds
-
- 1979 New York Yankees
-
- 1985 Detroit Tigers
-
- 1987 New York Mets
- Each of the last 3 100-win World Series winners lost in the LCS the next year
The Verdict
Based on the research, I believe the Red Sox have a 20 to 25% chance to repeat. I believe that there is still a select group of elite teams that could win the World Series this year. World Series repeats are less common during the 162-game era as just 9 of 56 (16%) World Series winners repeated. However, 4 of those teams were 100-win teams. World Series winners who did not reach 100 wins in this time frame only repeated 12.1% of the time since 1961. That’s more like a 1 in 8 chance. 100-win World Series winners have repeated 26.67% of the time during the same time frame. I think the significance of being a 100-win team helps improve the Sox chances to repeat.
However, as much as I hate to admit it as a huge Boston fan, I am sticking with my prediction that the Sox will fail to reverse the trend of World Series winners. I think they will lose in the ALCS to either the New York Yankees or Houston Astros. The odds are stacked against the Sox reaching 100 wins as well since only 4 of the 15 100-win World Series winners even reached 100 wins again the next year. I don’t think the Red Sox will reach the century mark but will come close at somewhere between 92 and 96 games. A bullpen with no proven closer to start the season helps support my prediction A World Series repeat is unlikely to happen, though you shouldn’t rule it out yet.
Alex Cora did wonders for this team last year, so maybe he’ll be able to recreate the magic of 2018. If he can, there’s no reason why he shouldn’t be 2019 AL Manager of the Year.
That’s all for today’s Baseball Bits. After all I have accomplished in the last 5 years, I look forward to creating even better content over the next 5 years. Stay tuned for more soon, including the next portion of my MLB Preseason Power Rankings.
