Friend of the VORG (and fellow you should definitely follow) Doug Kern asked me the following this morning:
@dianagram Brewers face B2B Montgomerys (CHC Mike Thu, NYY Jordan Fri). Cubs broadcast claimed 9th ever but I haven’t seen list. Thoughts? ☺

After a bunch of data wrangling with the Retrosheet game logs, I don’t know about the Brew Crew having experienced this phenomena nine times, but here is what I was able to come up with in terms of one team facing pitchers with the same last name in consecutive games, through 2016. If there is only a last name listed, just trust me when I say that each pitcher had a different Retrosheet ID. I’m not 100% certain on this list, but I think I’m ….. in the ballpark.
