Left wing Brian Maloney chipped in a goal and three assists in the losing effort while Peoria center Troy Riddle paced his club with three goals.
Chicago (1-1-0-0) received goals from five different players.
Peoria (0-1-0-1) earned a point in each of their two preseason matchups against the Wolves.
The Wolves cracked the scoreboard early in the first period, 1-0, when right wing Vlad Serov dug out a loose puck in the corner and threw it to the crease. Right wing Pat Dwyer charged the net and managed to deflect the puck past Rivermen goaltender Curtis Sanford at 1:18 of the opening frame.
Sanford posted eight saves on 11 shots before being replaced by Matt Underhill at 29:15. Underhill (1-0) recorded 14 saves.
Just over three minutes later, Serov added to the Wolves lead, 2-0, when linemate Brian Maloney wheeled through the top of the slot and dished a pass between two defenders. Serov positioned himself then one-timed the feed past Sanford at 4:20 of the first stanza.
Peoria cut into the lead, 2-1, midway through the first on a power-play goal off the stick of left wing Konstantin Zakharov. Zakahorov one-timed a feed, stick-side, past Wolves netminder Kevin Reiter at 6:04 of the opening period.
Reiter recorded 12 saves on 15 shots before being replaced by Tuomas Tarkki at 29:15. Tarkki (0-1) turned aside 13 of 16 shots.
Then, the Rivermen evened the game at two apiece when defenseman Trevor Byrne ripped a shot through traffic in the crease. Reiter kicked out the shot but was tripped up, allowing Troy Riddle time to put the rebound into the unguarded net at 13:05.
Early in the second period, Maloney gave Chicago back the lead, 3-2. The Wolves left wing took a pass in the crease from Serov, pulled Sanford out of position and tucked a shot over the goal line at 2:19 of the middle frame.
Midway through the second period, Peoria tied it, 3-3, when forward Chris Durno broke the Wolves zone and dumped a shot on goal. The puck bounced off Retier and trickled into the crease before Riddle swooped in and banged it into the net at 9:15.
Forty-five seconds into the third period, DiSalvatore gave the Rivermen the lead, 4-3. Left wing Charles Linglet snapped a feed across the slot that bounced off a Wolves defender's stick and onto the tape of DiSalvatore. He then quickly snapped a shot that beat Tarkki, top-shelf.
Then, Peoria tacked on to its lead, 5-3, when left wing Justin Maiser beat a Wolves defender to a loose puck in the corner, cruised to the front of the crease and tucked the puck in between Tarkki and the right post at 6:20 of the third period.
Just over three and a half minutes later, Chicago cut back into the lead on the power play, 5-4. Center Jared Ross flew into the Rivermen end, stickhandled around two defenders and threaded a pass across the crease that left wing Colin Stuart one-timed into the unguarded net at 9:52 of the final stanza.
Riddle completed the hat trick and regained the two-goal lead for Peoria, 6-4, on the man-advantage, when he deflected a shot past Tarkki at 12:09 of the third stanza.
Late in the period, the Wolves made it a one-goal deficit when Maloney found Ross alone in the slot with a pass. The Chicago center quickly wristed a shot over Underhill's shoulder at 17:14 of the third stanza.
The Wolves remain in the Chicago area for their next preseason tilt against the Milwaukee Admirals at West Meadows Ice Arena in Rolling Meadows on Thursday at 7 p.m.
