I think his change up is #5
oh, maybe ur right if we see miyuki senpai hand when give sign for change up. probably his number 1 is his straight fastball that can accelerate it speed.
Well at one point it was number five xD but I think the author keeps changing the signs so I'm not sure about that. The change up is definitely one of his numbers and I believe so is the palm change up and the vulcan change up. If you Google it there is a wiki with more info.
hope author will reveal all of sawamura complete number soon and make it official name. like number 7 custom cutter (translator ch 36 call it overhauled cutter)
gah,,, not enough... 2 week and only get tanother cliff hanger
（/TДT)/
dunno why i think sawamura number 11 gonna get hit by mima, and it'll give him some more tought to complete it.
and yes... i wanna list of his number, so far only known several number. number 2 2 seamer, number 4 4 semaer number 7 cutter and now number 11 splitter. so where number 1,3,5,6 (we see number 6 in designated chapter but dunno the name),8,9,and 10?
