Is my guy friend at work starting to develop a little crush on me?

The other day a guy at work was like “how’s your night going” and couldn’t stop awkwardly giggling and smiling while asking me that. I asked him why he was laughing and he said he saw something funny on twitter earlier but it seemed out of place. Because he just started uncomfortably smiling. He has trouble maintaining eye contact but is still really social at the same time lol so it’s weird. I’ve definitely seen him smile like that at an awkward / funny moment before but it was usually when something funny happened.
Today, some of the guys were playing a basketball game in the news room and he was like “Ashley, you might want to watch this” and I kept saying why and he proceeded to try to throw a ball into the hoop ( but missed lol ) after he did it, he apologized for missing the shot I don't know why he told me to watch him. He got quiet the rest of the night and kind of faced away from me at his desk ( we sit side by side ) but he took a phone call for me later that night when I was busy. He could’ve been focused on his work but still lol. Why did he ask me to “watch him”
