Ritchie notched an assist in Monday's 5-1 loss to the Blues.
Ritchie served a one-game suspension Sunday versus the Blackhawks after he slashed Kevin Shattenkirk on Friday. Returning to the lineup Monday, Ritchie was listed on the fourth line, but he saw 16:59 of ice time. The 26-year-old helped out on Nick Schmaltz's third-period tally. Through 18 games with the Coyotes, he has 11 points, 54 hits, 53 shots on net and 18 PIM after struggling with the Maple Leafs to begin the season.
