He'll look to stay hot and help Phoenix earn at least a point for the seventh straight game when it hosts the Calgary Flames on Tuesday night.
Ribeiro has recorded at least 51 points in the last eight full NHL seasons and finished with 13 goals and 36 assists for Washington in the lockout-shortened 2013 campaign.
The 32-year-old surprised many by signing a four-year, $22 million free-agent contract given the uncertainty of the franchise at the time, but the acquisition is paying dividends for the Coyotes (5-2-2).
After going without a point through three games, Ribeiro has three goals and four assists over the last six - a stretch in which Phoenix has gone 4-0-2. He scored twice in the third period of Saturday's 5-2 win over Detroit.
"I'm getting more comfortable, that's for sure," Ribeiro told the team's official website. "When the team plays good everyone looks good, so it's getting easier and hopefully I can keep helping the team."
Ribeiro has seven goals and eight assists during a nine-game point streak against Calgary, and coach Dave Tippett expects him to keep playing at a high level.
''He finds a way to have an impact on the game,'' Tippett said. ''He's a quirky player, but he can do things for you.''
Mike Smith made 31 saves Saturday and became the 11th goaltender in NHL history to score a goal when he fired the puck into an empty net as time expired. He's 3-0-2 with a 2.53 goals-against average during the team's hot stretch.
''Obviously I'm thrilled with the way we played. It's just a bonus to be able to score a goal in this league as a goaltender," Smith said. "We did a lot of really good things against a good hockey team.''
Phoenix, though, is 1-3-1 in its last five meetings with Calgary, with Smith starting each contest and posting a 2.96 GAA. He could be in net again against the Flames, who ended a two-game skid with a 3-2 win at Los Angeles on Monday.
Calgary (4-2-2) did all its scoring on the power play, including T.J. Brodie's goal with 29.7 seconds remaining. It went 5 for 28 with the man advantage in its first seven contests.
''We want to jump up into the play as much as possible, and if there's opportunities there, we want to take them,'' Brodie said.
Sean Monahan, the sixth overall pick in this year's draft who turned 19 on Oct. 12, scored for the sixth time in seven games. Mike Cammalleri scored in his season debut after being on injured reserve with a hand injury.
''Real gutsy effort," coach Bob Hartley said. "There would be power plays on both sides, and I think we won the special teams battle.''
Karri Ramo made 27 saves Monday to earn his first win since beating Florida on March 14, 2009, with Tampa Bay, but Joey MacDonald should be back in net for this contest.
MacDonald is 3-1-1, though he has a 2.99 GAA and .891 save percentage. He made 29 saves opposite Smith in the most recent meeting with Phoenix on April 12, and Mark Giordano scored in overtime to give the Flames a 3-2 victory.
