Marcel Goc was the only successful shootout 2 win in the opener of a home-and-home series against the Lightning.
Marc-Andre Bergeron lit the lamp twice in the third period for the Lightning, who finished a 1-2-2 road trip to start the season. Tampa Bay will open its home slate on Monday against its intra-state and Southeast Division rival.
Jovanovski's power play tally accounted for the only goal in the first two periods, as his slap shot from the point hit off both a skate and stick in front before finding the back of the net at 11:48 of the opening stanza.
A silent second period was the calm before an entertaining final 10-plus minutes. Bergeron tied things with a slap shot at 9:43, only to have Versteeg answer with a power play goal off a cross-ice pass from Dmitry Kulikov with 2:55 to play.
The Lightning countered 39 seconds later when Bergeron's one-timer from the top of the right circle beat Theodore.
