Healy hit a pair of three-run homers for a career-best six RBI, lifting the Mariners over the Chicago White Sox 8-2 Sunday.
"I want to help this team win every single day whether I'm in the lineup or not," Healy said. "And I'm going to find a way to do that. When Cano comes back or whatever, I don't care."
Cano is eligible to return in mid-August from an 80-game suspension for a positive drug test. Seattle acquired second baseman Dee Gordon in Cano's absence, and Mariners general manager Jerry Dipoto said last week that Cano will play every day when he returns, mostly at first.
"Things like that are out of my control," Healy said. "I'm not a guy who needs to try harder. I think I try too hard at times. It isn't the first time this has happened to me or anyone else in this game."
Healy homered in a five-run first off Reynaldo Lopez (4-8) and in the eighth against Hector Santiago, giving him 20 homers and 53 RBI this season. Healy had five-RBI games against Colorado on July 8 and for Oakland versus Toronto on June 5 last year.
He entered with a .236 batting average and .268 on-base percentage.
"I want to compete and I want to win and I want to go where this team hasn't gone before," Healy said. "I want to be a big part of that. My job is to make their job as hard as possible when the moment comes."
Marco Gonzales (11-5) won his fourth consecutive start, allowing two runs and four hits in 6 1/3 innings.
"Marco really threw the ball well again today," Mariners manager Scott Servais said. "He changed speeds and was really attacking."
Gonzales did not give up a hit or a walk in the first five innings
"I was trying to stay aggressive," he said. "They are a team that tends to chase, so I wanted to get ahead in the count early. I was happy where my stuff was today. I take pride in getting a win."
Lopez (4-8) allowed five hits and four walks in five innings.
"He was leaving pitches out over the plate a little bit, and he got roughed around," White Sox manager Rick Renteria said. "But he settled down and got us through five when it wasn't really his day."
Mariners: C Mike Zunino came off the 10-DL after recovering from a bruised left ankle bone. C David Freitas was optioned to Triple-A Tacoma. ... Manager Scott Servais said RHP Erasmo Ramirez will make another rehab start this week at Tacoma and probably pitch three innings.
Mariners: LHP James Paxton (8-4, 3.70) is expected to come off the 10-day DL to start Tuesday night against San Francisco. Paxton went on the DL on July 13 because of lower back inflammation. He threw a bullpen session Saturday.
