The Ducks found themselves in desperate need of more offense after scoring a league-low 28 goals through their first 17 games.
Ritchie was the 10th overall pick in the 2014 draft. The 19-year-old forward had nine goals in 12 games in San Diego to begin his first pro season.
He made his debut in Monday night's 4-1 win at Carolina with no goals in 10:39 of ice time.
Sgarbossa was Ritchie's center in San Diego.
Wagner was scoreless with 17 penalty minutes in 11 games for Anaheim. Friberg was scoreless in five games, and Holzer had one assist in seven games.
