When you see her on campus stop her and say
"Excuse me, are you on the softball team?"
Yes
"Oh I thought I recognized you, you're that new girl right?"
Yes haha
"I'm name, nice to meet you (shake hand)"
"I'm sorry, you have the most interesting (comment on her yoga pants or something)"
Then make some more small talk without asking questions or smelling needy
Then say
"Hey I gotta go but you seem actually pretty cool. I'm going to x event, you should come"
Hopefully she says yes here or you know how to handle objections
"Ok, what's your number"
Text her a bit, invite her to said event, talk to her more there, then continue to hang out
But honestly, you sound too invested in her to not come across as needy. Just feedback, but still go out there and execute baby. The only way you will disappoint me is if you chicken out when you see her walking on campus, and then in 20 years you are sitting on your couch thinking what could have been if you sacked up.
