AMES, Iowa (AP) -- DeMarre Carroll followed a below-average outing at Texas with one of the best games of his career, helping Missouri reach the 20-win mark for the first time since 2002-03.
Carroll scored a career-high 31 points and Missouri never trailed in beating Iowa State 82-68 Saturday.
Kim English added 16 for the Tigers (20-4, 7-2 Big 12), who shot 57 percent from the field and 9-of-16 from 3-point range in picking up their seventh win in eight games.
Carroll, who had just 13 points in the win over the Longhorns on Wednesday, responded by shooting 14-of-20 from the floor with nine rebounds, five assists and a pair of blocks.
"I thought he was a force," Missouri coach Mike Anderson said of Carroll. "I thought he was like a beast."
The Tigers handed Iowa State its worst loss of the season, 77-46, at Mizzou Arena back on Jan. 17. Though the Cyclones put up a better fight on Saturday, the outcome was never in doubt after Missouri went on a decisive 15-4 run early in the second half.
With shot after shot rattling in and out for Iowa State, Carroll hit a 3-pointer, Marcus Denmon drilled a fadeaway 3 over Bryan Peterson and Leo Lyons hit a tip-in that pushed the Tigers ahead 58-44.
Matt Lawrence then gave Missouri its biggest lead, 61-44, on a 3 with 11:25 left. Though Iowa State answered with eight quick points, English hit a 3 and Carroll scored to squash any notions of a comeback.
"The thing about this team is, we have a lot of options," Anderson said. "We shot the ball well early on, and I thought in the second half our defense really dictated the tempo of the game."
Craig Brackins had 16 points to lead five players in double figures for Iowa State (12-11, 1-7), and Diante Garrett added 13 points and tied a career high with 11 assists.
The Cyclones have lost six in a row and three straight at home to Big 12 opponents for the first time since 2006. Worse yet, Iowa State has been outscored by an average of 15 points a game during its current skid.
"Today, we just weren't good enough," Iowa State coach Greg McDermott said. "Missouri was much better today and that's about as simply as I can put it."
The Tigers had pushed a six-point halftime lead to 43-33, as Carroll followed a breakaway dunk with a layup off an Iowa State turnover. Missouri could have later gone ahead by 12, but Brackins blocked a Carroll shot in the paint and hit a pair of baskets to pull the Cyclones within 46-40.
Iowa State couldn't close the gap any further, though, and the Tigers quickly put the game out of reach.
This is the first 20-win season for Missouri under coach Mike Anderson, who led Alabama-Birmingham to four straight 20-win seasons before taking over in Columbia.
"Twenty is the number right now, and hopefully it's going to be more than that," Anderson said.
The Tigers hit six of their first seven shots to jump ahead 13-4. Iowa State eventually pulled within 31-29 on a Jamie Vanderbeken 3, but English answered with a 3 to help Missouri take a 37-31 lead into halftime.
Both teams shot well in the first half. Iowa State hit half of its tries from the field -- despite going just 3-of-12 from 3-point range -- and Missouri shot 57 percent, as Carroll and English combined to go 12-of-14 from the floor.
"My teammates just found me, got me the ball, saw I was hot," Carroll said.
The Tigers have a big week ahead of them, starting on Tuesday when 21st-ranked Kansas visits Mizzou Arena. This could have been a trap game for Missouri -- which had dropped road games at Kansas State and Nebraska -- but the Tigers played their game from the opening tip.
Missouri, which entered play second in the nation in assist-to-turnover ratio, had 28 assists on 35 field goals and just nine turnovers.
"I'm very proud of our guys for the focus they had," Anderson said. "I thought we got better today."
