"We did some things well early and got out of the first period 0-0," Miller said. "They've been scoring 3-4 goals in the first for a while. Third period, we had that zone time and made it count."
Rowney, who missed the previous 20 games because of an upper-body injury, made it 3-1 at 5:39.
Miller made key saves against Alex Killorn from right in front of the net at 6:40 and Nikita Kucherov's one-timer at 18:06 while the Lightning were on a power play and had Domingue pulled for an extra attacker.
"We were in good spots and I thought we stayed pretty tight," Miller said. "Even on that 6-on-4, we had two and three guys in the corners and we won those battles. It was good to see."
Josh Manson gave the Ducks a 1-0 lead at 12:04 of the second period from the low slot after Adam Henrique couldn't stuff the puck past Domingue.
