OK, I just got this one done and there's no sense in sitting on it. Here's
Messer Street Grounds, home to the only major-league baseball team that the Ocean State has ever (full-time) hosted, the National League's
Providence Grays. Messer Street was home to the Grays for their entire tenure, from 1878-1885, including pennant winners in 1879 and 1884. The latter team is particularly famous for winning the
first "World Series", with
Old Hoss Radbourn setting the record for wins in a season in the process.

This one was somewhat easier than I was expecting, given the discussion in this thread. As noted here and in discussions on the internet, the shape of the lot seems to have been square but with a cutout for a few houses that already existed, which accounts for the short left field line. The depiction I put in the last post suggests that there wasn't anything built out past the center field fence, and playing with the distances suggests that the distance to CF could have been more like 325-330 feet than 318. Regardless, even 330 feet is too shallow for OOTP, so I tweaked things so it was 350. I seet the dimensions in the Park Profile to be what's out there in most of the sources, though, so it doesn't match the model dimensions. I don't expect this to cause any problems. The park factors are also all set to 1, per usual practice for these 19th-century stadia.
For those curious, the background is from Fall River, so pretty close by but not actually Providence.
As usual, let me know if you have any feedback! I think this was the last unmodeled NL19th century ballpark that was used for a significant period of time (3 years plus, maybe even 2 years plus). I'll take a look at what's out there and most useful, it may be that I do a few West Coast/non-MLB parks for a bit...
