Mailloux logged an assist in Saturday's 5-4 shootout loss to the Kings.

EDGE Analysis

Mailloux ended a 16-game point drought with the helper. In that span, he had 10 shots on net, 20 hits and a minus-5 rating. The Blues have liked him enough to sign the defenseman to a one-year contract extension Jan. 13. Mailloux has produced a meager three points with 31 shots on net, 33 PIM, 48 hits, 23 blocked shots and a minus-22 rating over 37 outings this season.

Mailloux signed a one-year, $850,000 contract extension with the Blues on Tuesday.

EDGE Analysis

Mailloux has produced just two points over 31 appearances with the Blues this season, but the defenseman has done enough to keep the team's interest. He'll likely finish out 2025-26 in a third-pairing role, and he'll have to compete for his spot in 2026-27, though his contract is a one-way deal.

Mailloux scored a goal on two shots and added five PIM in Friday's 3-2 win over the Blackhawks.

EDGE Analysis

Mailloux had a busy first period, scoring at 3:41 of the frame before fighting Colton Dach later on. The 22-year-old Mailloux's tally was his first goal as a Blue. He's seen limited usage on the third pairing this season, picking up two points, 21 shots on net, 27 hits, 14 blocked shots, 17 PIM and a minus-17 rating through 20 appearances.

Mailloux notched an assist, two shots on goal and two hits in Wednesday's 3-2 overtime loss to the Devils.

EDGE Analysis

Mailloux played for the second time with the Blues after a slow start to the 2025-26 campaign led to a demotion to AHL Springfield. The 22-year-old blueliner is still a long way away from playing a key role -- the Blues' defense is dominated by the top four, with little ice time for those players on the third pairing. That's Mailloux's role whenever he's in the lineup, and he's earned an assist, a minus-13 rating, 16 hits and seven blocked shots over 11 outings in that spot.

Mailloux was recalled from AHL Springfield on Saturday.

EDGE Analysis

Mailloux has two goals in five minor-league outings this season. He hasn't earned a point while contributing five shots on net, six blocked shots and 13 hits in nine NHL appearances this campaign. Mailloux will be an option for Saturday's matchup against the Islanders, but it's unclear if he will be in the lineup.

Mailloux was assigned to AHL Springfield on Sunday.

EDGE Analysis

The Blues summoned Hunter Skinner from the minors in a corresponding move. Mailloux hasn't earned a point in nine appearances this season while posting five shots on net, six blocked shots and 13 hits. He has been a healthy scratch in four of the last five games and should see regular playing time in the AHL before a potential recall to the big club.

The Blues traded for Mailloux from the Canadiens on Tuesday in exchange for Zachary Bolduc.

EDGE Analysis

Mailloux has one year remaining on his contract before he becomes a restricted free agent in 2026-27. The right-shot blueliner provided two goals and four points in just seven regular-season games with Montreal in 2024-25, and he'll look to earn a full-time role in the bottom four with St. Louis this coming season.

Mailloux was reassigned to AHL Laval on Sunday.

EDGE Analysis

Mailloux was a healthy scratch in Sunday's 5-3 loss to the Lightning. He has two goals, two assists, 10 shots on net, eight blocked shots and nine hits in seven NHL outings this season. He might return after the 4 Nations Face-Off break to be a depth option for the Canadiens.

Mailloux scored a goal and added three hits in Wednesday's 6-3 loss to the Kings.

EDGE Analysis

Mailloux has racked up two goals and two assists over six outings at the NHL level this season. This was his first appearance with the big club since Oct. 29. Mailloux will compete for playing time with Jayden Struble while Kaiden Guhle (quadriceps) is on the mend. Mailloux has added nine hits, seven blocked shots and a minus-3 rating. He's in a third-pairing role, but if he keeps putting up points, he may be worth considering in DFS or as a streaming option in season-long formats.

Mailloux was called up from AHL Laval on Tuesday.

EDGE Analysis

Mailloux represented Laval at the AHL All-Star Classic on Monday, and now he'll rejoin the Canadiens, at least for the rest of their road trip. It's unclear if he'll play Tuesday versus the Sharks.
