The Library of Congress has a free database of scanned newspapers (I don't think it is as extensive as newspapers.com).

I found a few mentions in a quick search of 3/10-3/11 and Cubs - it looks like Rogers had a good two-game series vs. the Los Angeles Angels:

You might have more luck if you spend a little more time. I suggest looking at the LA and Chicago papers for those dates, without a keyword, and looking at the sports sections. Sometimes the search feature doesn't pick up all of the words as it is searching an image.
