Major League Baseball Players Who Debuted on Their Birthday

On Thursday night (May 31, 2018), Shane Bieber made his major-league debut with the Cleveland Indians. His performance was largely non-descript: not historically great or notably bad (5.2 IP, 4 R, 8 H, 1 W, 6 K). But one thing was particularly noteworthy about Bieber's debut: it came on his 23rd birthday.

This got me curious about how many players in major-league history have debuted on their birthday. According to Baseball-Reference, Shane Bieber was the 19,266th player in major-league history. Assuming my database is accurate, it turns out that Bieber was the 38th player in major-league history to debut on his birthday - making the frequency of birthday debuts 1 in every 507 players in major-league history.

The next table shows the 37 players who made their major-league debut on their birthday. The players who are not linked played their entire major-league careers prior to the seasons for which Retrosheet has released play-by-play data (i.e., since ). For players with links, the links are to these players' player pages. The last column of the table shows a player's career pWORL - pWins over replacement level - for those players for whom I have calculated Player won-lost records.

Finally, setting aside the first five players on the list (none of whom had much of a career anyway), the top five players in major-league history who debuted on their birthday, ranked by career pWins over replacement level, are shown next.

There's quite a gap between players #2 and #3 here as well as between #4 and #5. Interestingly, the top four players among birthday debuts were pitchers. If he can stay in the Indians' rotation for a few seasons, perhaps Bieber can make this table an all-pitcher table.

All articles are written so that they pull data directly from the most recent version of the Player won-lost database. Hence, any numbers cited within these articles should automatically incorporate the most recent update to Player won-lost records. In some cases, however, the accompanying text may have been written based on previous versions of Player won-lost records. I apologize if this results in non-sensical text in any cases.
