Erakovic, ranked 71st in the world, admitted Lisicki's retirement was unfortunate but she wasn't about to let that get in the way of her elation - and relief - and having earned her maiden title.
"First off, I'm just really happy,'' Erakovic said during the post-match presentation. "A lot of work and effort has gone into this. I'd like to thank my family ... and I would like to thank my coach Chris [Zahalka].''
In addition to the $48,000 prizemoney and the Tennessee-themed trophy which resembled a cross between a guitar and a tennis racquet, Erakovic revealed one more reward for her win.
"We have been together for a few years now and we do a really good job,'' Erakovic said of Zahalka. ``We have a good time and we made a bet that if we win a WTA title we are going to jump out of a plane.''
That's something Lisicki is unlikely to be doing in the near future, with the world No 40 explaining the reason for her retirement on Twitter following the match.
"Very sad that I had to retire in the final as I've been sick last 3 days. Gave it all I had,'' she wrote. "Congrats to Marina for a great week and her 1st title!''
The German may have been confident of claiming victory were it not for illness, especially after beating Erakovic in three sets earlier this month, but the Kiwi has played good tennis this week in Memphis.
She beat last year's champion Sofia Arvidsson en route to the final, avenging last year's defeat at the hands of the Swiss, while she also eliminated American world No 66 Jamie Hampton.
Erakovic's breakthrough win should boost her world ranking into the mid-60s, short of the high of No 39 she achieved last May.
