This series went just about as expected, especially with Jusuf Nurkic out for most of it, and the Warriors now get plenty of time to rest up while they wait for the victor of Clippers-Jazz.
His health is the most important matter at the moment, but even with Kerr unable to be on the sidelines during games, he will still be involved with game planning for the Warriors as they advance.
Meanwhile, the Atlanta Hawks drew level with the Washington Wizards after a 111-101 win.
Golden State Warriors head coach Steve Kerr, left, talks with TNT broadcasters Brent Barry, center, and Marv Albert before Game 4 of an NBA basketball first-round playoff series Monday, April 24, 2017, in Portland, Ore.
In Kerr's absence, assistant Mike Brown will continue to fill in as the acting head coach. Portland will use the energy of the home crowd to build an early lead, but Golden State will flip a switch in the second half - probably early fourth quarter - where they will finally take control of the game. Curry swished a long 3-pointer that made it 104-77 late in the third quarter and the Blazers couldn't catch up.

Golden State leads a best-of-7 playoff series 3-0 for only the fifth time in franchise history, but the third time in the last three postseasons.
The Toronto Raptors, meanwhile, moved into a 3-2 lead over the Milwaukee Bucks after recording a 118-93 victory at Air Canada Centre. JaVale McGee made a highlight-reel alley-oop dunk in route to a 45-22 lead after the opening quarter. He played three tune up games as Golden State headed into the playoffs with the top record in the league.
Nurkic developed chemistry with Lillard and guard CJ McCollum, going on to average 15.2 points, 10.4 rebounds and 1.9 blocks in 20 games with the Blazers.
The two stars put up similar numbers in their first season playing on the same team.
Six players scored in double figures for the Warriors, who shot 53.5 percent from the field, including 17 of 29 (58.6 percent) from 3-point range.
Of course, the most obvious reason why the Warriors are better is the signing of Kevin Durant.
Now, a series marked by ill feelings that went so far as Markieff Morris calling Millsap "a crybaby" is down to a best-of-three. He's a five- to six-minute guy. This, of course, brings us back to how they were able to sweep their opponents while almost all the remaining series are scheduled to go at least six games.
Kyle Lowry added 16 points and 10 assists for the Raptors while Serge Ibaka contributed 19 points, DeMar DeRozan had 18, DeMarre Carroll added 12 and Cory Joseph scored 10 off the bench.
Norm Powell career-high 25 points for Toronto.
