Allen recorded his 137th win with the Blues in his 250th career start, making 25 saves on Thursday. Joseph needed 274 starts to reach 137 wins.
Allen now trails only Mike Liut (151) for the franchise record in wins. Liut's mark has stood since the 1984-85 season.
"It's definitely a goal of mine, and I think the rest of the Blues, to get to that No. 1 spot," Allen said after Thursday's win. "I had no idea about (the record) to be honest, but a few people brought it up to me in the last week so that's the only reason I have it in my head. It's pretty cool. I've been here for awhile, some fun exciting years, but I'll thank the boys for potting some goals for me to get that tonight."
Allen, who made his debut with the Blues in the 2012-13 season, also ranks third in franchise history in shutouts (19), trailing only Glenn Hall (20) and Brian Elliott (25).
