The Timberwolves needed rescue from the depths of desperation Wednesday and they received it from an unforeseen place during a 106-99 comeback victory over Philadelphia:

Their underperforming, underused and much-maligned bench.

Hung over probably more emotionally than physically from Tuesday’s lopsided victory at Detroit, the Wolves surrendered 39 first-quarter points and trailed by 19 Wednesday at Target Center to an opponent that had lost seven of its previous eight games.

They were saved by a 58-38 second-half reversal in which rookie reserve Robbie Hummel scored all of his 10 points in the fourth quarter. He also provided the pulse during a 10-0 run that featured his presence and big Nikola Pekovic’s scoring while transforming the game.

The Wolves won on the second night of back-to-back games for only the second time in seven tries this season. They also swept back-to-back games for the first time in a year — Dec. 14-15, 2012 — and seventh time in the past five seasons.

They did so with their bench — lengthened from as few as two some nights this season to four who played nearly 12 minutes or more Wednesday — holding their own and being outscored only 25-24 against the Sixers reserves.

“A lot better than the first, that’s for sure,” Wolves star Kevin Love said when asked about his team’s bench play after he delivered just another 26-point, 15-rebound, five-assist night.

Hummel’s fourth-quarter play — those 10 points set a career high — allowed his team to end the evening in celebration after a first quarter coach Rick Adelman termed “awful.”

The Wolves withstood the 76ers’ 16-0 run that ended the first quarter by getting within 13 points at halftime and within three by third quarter’s end on an evening when they didn’t lead until 8½ minutes remained in the game.
