Text Widget makes title a list item

Hi,

I’m new to wordpress theme building but I’m getting along very well with it. I’m building a basketball blog (Boston Celtics) atm. I’ve inserted the generic Text-Widget (Arbitrary text or HTML) to the header to display the upcoming game of the Team.

Problem is that the widget automatically makes the widget’s title a
list item.

sourcecode:

<li id="text-2" class="widget widget_text"><h2 class="widgettitle">Upcoming</h2>
			<div class="textwidget"><p>LAL at BOS</p>
</div>
		</li>

Is there a way to change it, so it’s not a list items? Hot can I edit the generic Widgets?
