Remove Hover Text Decoration in Site Title

So, I can’t figure out how to remove the drop shadow from the site title on a hover state (I’m viewing the webpage in Chrome Version 35.0.1916.114 m) The site I’m working on is atmotter.com. I want to remove any fanciness on hover state for the site tile: Andrew T Motter. I’ve tried the following CSS in my child theme:

.site-title a,
.site-title a:hover,
.site-title a:active {
text-decoration: none;
transition: none;
}

I’ve also tried including !important to override any other CSS that might be taking precedence with no luck :(. Any thoughts?
