Yeah, a single blast wouldn't kill Logan, but it would effectively block that fastball. If Spidey is launched up at BB I'm not sure how well he'd be able to dodge in midair with nothing to alter his trajectory. Another thing to remember is that if BB dodges a fastball then Colossus basically bfrs one of his teammates. Depending on how hard he's throwing of course.
He threw Logan fast enough and hard enough to catch up to a ship that was a reaching escape velocity pretty quickly, and you would be surprised at how often Spidey dodges stuff in mid air.
They could also do a double triple Fastball. Toss Logan, then toss a huge object, then toss Spidey right behind it. Beetle won't see Spidey coming.
