Sorry for barging in... I figured this would be as good a time as any, with StubbornOne's latest release being uploaded here.
I've been reading this for a few years now and as it turns out, not having anyone to fangirl/fanboy with over an unpopular series turns you into a mildly obsessive fan. So I'm just going to dump some info on the yuri content here in case anyone is interested or hesitant to start reading, and then I'll go back to lurking.
Compared to other female-centric sports manga that last more than 3 volumes, I'd say that Baggataway has less yuri subtext than Saki (if you consider Saki to be a sports manga in a way), but more than... almost everything else? Seriously, yuri is criminally underrepresented in sports stories.
I'm using spoiler tags, but I will only mention the relationships between the characters, nothing related to the games or the characters' background.
First off, a clarification: chapter 11 introduced a bunch of male characters, and for a while I was worried this meant that some of the main girls would be paired off and that Baggataway would turn out to be yet another sports/manga with as much focus on romance as sports, but I never once got the feeling that they were intended to be love interests for any of the girls. One of them has a crush on one of the girls, but so far he has managed to talk to her exactly once, and he promptly got a nosebleed and ran away, and then another character basically laughed in his face and told him "unrequited love is hard". The journalist guys are mostly there for exposition about lacrosse rules and comic relief. Of course, there's always the possibility that the last chapter will introduce romance with zero foreshadowing, but at this point it seems highly unlikely.
As for the yuri subtext, the main character gets a rival in volume 5, but their interactions make them seem more like best friends or soulmates than rivals. They even use the red string of fate metaphor. The rival is half-Australian and her gaijin upbringing is used as an excuse for her to be very affectionate with Sora (hugs, kiss on the cheek). She basically becomes Sora's reason to get better and win.
Danchou is definitely a baby lesbian. Her crush on the captain can be seen from space, but later on she also gets a crush on Jinnoharu, the captain's rival, and their interactions are great. It's most likely one-sided though.
I might be getting ahead of myself here, but I'm fairly sure that Chikushi's captain, Shihatsu, and her best friend, Ichizaki, are a couple. They're the closest thing to a couple in a series with no romance, in any case. They have a few very sweet scenes together, including a flashback to the time when they started calling each other by their first names that's full of romantic overtones and symbolism. They worry about each other, they occasionally hold hands and at one point they share a hug that didn't seem platonic in the slightest.
If you like shipping rivals, Shihatsu also has chemistry with Jinnoharu. Their teams play each other again later on and stuff happens, but to sum up they're both very important to each other. Some of Jinnoharu's teammates actually assumed that they were a couple. In fact, the second Chikushi vs. Kokura Central game can be seen as the expression of a love triangle. I swear it seemed like Ichizaki and Jinnoharu were fighting over Shihatsu at times. Jinnoharu has subtext with her best friend Sakai as well (some of their teammates also thought that they were together).
There's a few more pairings that technically don't really have any subtext but look good together, and the absence (for the most part) of love interests means you can let your imagination roam free. With such a large cast, there's a lot of different pairing types: childhood friends, ojou-sama and servant, teammates who work together reluctantly, senpai and kouhai... The list goes on.
There you go. I'm not sure whether any of this was actually useful to anyone, so as an apology for probably wasting your time, have some (badly translated and edited) Setamii cuteness.
And some Kanna x Shiho yuri service.
These are omake pages that some stores sell with the tankoubon. There are two more that are sort of yuri, but I haven't been able to track them down yet.
If you want more spoilers (plot, characters, specific pairings), just ask.
I hope the translations do get there eventually... If they don't, I've just been a complete asshole and teased stuff that will never get translated. I'm grateful that four volumes have been scanlated, in any case, and I hope that there's more to come.
TL;DR: Strong subtext, several pairings to choose from, no het romance involving any of the main characters as of volume 11. It's also a pretty good sports manga if you like the genre.
