Borussia Dortmund substitute Thorgan Hazard has scored twice to guide the German Cup holders to a 2-0 home victory over second-tier Ingolstadt and a place in the third round.
Julian Brandt provided both assists for Hazard, who came on in the 71st minute.
Dortmund had failed to impress before the goals, with Jude Bellingham hitting the crossbar in a rare first-half highlight.
There were even some whistles from the home fans at the break.
But Hazard and captain Marco Reus brought some urgency with their introduction and the Belgian scored a minute later after some good play on the right.
Brandt crossed again for Hazard's second easy finish in the 81st.
Dortmund again played without forward Erling Haaland, who is out with a hip muscle problem after previously missing three games with what the club said were muscular problems.
Goalkeeper Gregor Kobel was also out with a thigh injury, forward Donyell Malen had a gastrointestinal infection, and the trio of Reus, Hazard and Manuel Akanji all were on the bench at the start.
"We have to be careful with the guys," Dortmund coach Marco Rose said of his players' busy schedule.
Dortmund played in the Champions League last week, then the Bundesliga over the weekend.
They have another Bundesliga game against Cologne on Saturday before hosting Ajax in the Champions League on November 3.
High-flying Freiburg survived third-tier Osnabrueck 3-2 on penalties, in a match in which both sides were within moments of victory in regulation time and extra time before dramatic equalisers.
Hertha Berlin progressed with a 3-1 win at fourth-division club Preussen Muenster, who had a player sent off late in the first half when Nicolai Remberg was shown a second yellow card for diving.
It was Munster's second loss in the competition - they previously lost to Wolfsburg, who was subsequently thrown out of the tournament for using too many substitutes in the first round.
Bundesliga clubs Leipzig, 1-0 winners over Babelsberg, and Hoffenheim, who thumped second-tier Holstein Kiel 5-1, advanced along with third-division 1860 Munich, who edged Schalke 1-0.
