The major plus for the Dallas Mavericks that evolved from Sunday’s disappointing 103-99 loss to the Los Angeles Lakers was the superb performance turned in by forward Dirk Nowitzki.

In his best game this season, Nowitzki finished with season highs in points (30), rebounds (13) and 3-pointers (four). He also tied his season high in steals (three) and field goals made (11).

It was a major step forward for the 11-time All-Star, who underwent arthroscopic right knee surgery on Oct. 19.

“I’m just working my way back into it, and I feel good now,” said Nowitzki, who played 39 minutes against the Lakers. “Obviously I put in a lot of work since I came back — extra sessions, extra shooting, extra jumps and lifting.

“So it’s been a long road back. Even down the stretch [Sunday] my legs were good.”

Nowitzki, who plans to play at least through the 2015-16 season, has been experiencing a steady increase in productivity. Over his last five games, the 16-year veteran has averaged 21.6 points and 8.8 rebounds while shooting 52 percent from the field (39 of 75) and 71.4 percent from 3-point range (10 of 14).
