SACRAMENTO — One day after the Warriors signed All-Star center DeMarcus Cousins, rocking the NBA and improbably fortifying their present, they unveiled a piece of their future in first-round draft choice Jacob Evans III.

Evans made his pro debut in Tuesday night’s California Classic game against the Kings. This is not your father’s summer-league game, either: Golden 1 Center was nearly full, an energetic mix of Kings fans eager to see No. 2 overall pick Marvin Bagley III and Warriors fans eager to revel in their place atop the hoops kingdom.

None of Golden State’s five All-Stars showed up, of course, but the Warriors still coasted to a 71-54 victory. Evans made a solid first impression, collecting a team-high 13 points and five rebounds in 25 minutes.

“Jacob’s a great player — very feisty, he has some dog in him,” teammate Jordan Bell said. “He does a little bit of everything. ... He’s just a tough guy. He takes every (defensive) matchup personally, no matter who it is.”

Evans, a 6-foot-6 wing player and the 28th overall choice from Cincinnati in last month’s draft, started alongside (in part) Bell and Damian Jones. It took only a seven-minute, first-quarter stint for Evans to offer a snapshot of his skills and his shortcomings.

Skills: He jumped into the passing line to nab a nice steal, showing the defensive instincts that attracted the Warriors to him. Soon thereafter, Evans ran the floor and scored his first pro points on a fast-break layup.

Shortcomings: His outside shot isn’t exactly Stephen Curry-like, aesthetically or otherwise. Evans sort of pushes the ball toward the rim, in an awkward motion. He went 5-for-12 from the field, including 1-for-5 from beyond the arc.

At the same time, Evans’ performance matched his advance billing. He’s active, driving to the hoop with vigor and switching defensive assignments without hesitation. That should serve him well in today’s NBA, and especially with the Warriors.

Now Playing:

“I felt like I played pretty solid,” Evans said of his debut. “I know I can knock down more shots. … On defense, it’s all about being tough and having heart. I feel like I have pretty good instincts on the defensive end; that’s kind of what we pride ourselves on at Cincinnati.”

The Warriors selected Evans more for his defense than his offense. He wasn’t a big scorer in college, averaging 13.5 points as a sophomore and 13 points last season as a junior.

Also noteworthy in this three-obsessed world: His shooting percentage beyond the arc dropped from 41.8 percent as a sophomore to 37 percent as a junior.

So, yes, it would help Evans if he sharpened his shooting stroke. Still, the Warriors aren’t exactly in desperate need of more shooting; they will be happy if he plays defense and contributes in other ways off the bench.

General manager Bob Myers and his front-office cohorts no doubt noticed these other relevant numbers about Evans: Cincinnati was 83-22 in his three years there. That sounds positively Warriors-like.

There was some question about Evans’ availability Tuesday night, after he missed Monday night’s summer-league opener with an injury to his right big toe. But he was cleared earlier in the day and showed no effects during the game.

Sacramento’s Bagley, one night after his impressive pro debut (18 points against the Lakers), struggled mightily against Bell and Jones. Bagley scored seven points on 3-for-16 shooting from the field.

Josh Magette scored 12 points for the Warriors. Bell had eight points (including one nasty left-handed dunk), seven assists and six rebounds, and Jones added six points and eight rebounds.
