RIP Erik Bollt (1967–2025)

My collaborator Erik Bollt died suddenly and unexpectedly last Sunday (the 7th). Erik is a well-known applied mathematician, and he was especially in the applied dynamical-systems community. Erik and I wrote two papers together, including our paper on mathematically modeling cow synchronization.

You can read about Erik's research on his web page and his Google Scholar page.

There will be a memorial article at some point.

Jeff Kent Elected to Baseball Hall of Fame!

Second baseman Jeff Kent has been elected to the Major League Baseball Hall of Fame by the Era Committee (which is the current version of the Veterans Committee. I am pleased that Kent is finally in the Hall.

Carlos Delgado did surprisingly well in the voting, so it sounds like he'll eventually make the Hall of Fame. Notably, Dale Murphy and Don Mattingly did not get enough votes (despite the fact that the Powers That Be seem to want them to be selected), and I agree that they should not be elected. Finally, I hope that Gary Sheffield, Barry Bonds, and Roger Clemens eventually make the Hall of Fame, but I won't be holding my breath (especially for the latter two).

Some Other 2025 MLB Awards

Major League Baseball announced various other awards (such as the Comeback Players of the Year) today.

2025 MLB Most Valuable Player (MVP) Awards

Major League Baseball announced it's 2025 Most Valuable Player (MVP) awards today, and here too there were no surprises.

In the American League, Aaron Judge of the Yankees win his 3rd MVP award in a close vote over Mariners' catcher Cal Raleigh. In the National League, Shohei Ohtani of the Dodgers won his 4th MVP. This was also Ohtani's 4th unanimous MVP award, and nobody else in MLB history (or in any of the four major US professional sports) has won more than a single unanimous MVP award. In MLB history, Ohtani's four MVP awards is second all time to Barry Bonds' seven MVP awards. Ohtani's four MVP awards have come in a 5-year span, which David Schoenfield recently compared to other all-time 5-year spans in baseball history.

2025 also marks the first time in MLB history that both AL and NL MVP awards were repeat winners from the previous year.

2025 MLB Cy Young Award Winners

Major League Baseball has announced its 2025 Cy Young Award winners, and again there are no surprises. Tarik Skubal beat out Garret Crochet in the American League (and did so slightly more handily than I was expecting) for his second consecutive Cy Young award, and Paul Skenes was a unanimous selection in the National League (with Christopher Sánchez receiving all 2nd-place votes and Yoshinobu Yamamoto finishing in 3rd).

2025 MLB Managers of the Year

Baseball's 2025 Managers of the Year were announced today, and both winners are repeat winners from last year.

Stephen Vogt of the Cleveland Guardians won the American League Manager of the year award for the 2nd year in a row, and Pat Murphy of the Milwaukee Brewers accomplished the same feat in the National League.
