EUGENE, Ore. (AP) -- Jonathan Stewart was in midseason form on Saturday as Oregon concluded its month of offseason practices with the spring game.

Stewart barreled and bowled his way to 41 yards on just five carries to help the Green team defeat the White team 20-6 at Autzen Stadium.

"Jonathan Stewart showed up today," Oregon coach Mike Bellotti said of his junior runningback. Stewart's top carry was for 22 yards. He also had two receptions for 10 yards.

The two units were drafted and coached by defensive coordinator Nick Aliotti (Green) and new offensive coordinator Chip Kelly (White) while Bellotti watched from the press box.

Second string senior quarterback Brady Leaf teamed with Stewart to lead the Green to a 20-0 lead midway through the third quarter.

Leaf completed 7-of-11 passes for 70 yards, including a 17-yard touchdown throw to tight end Ryan Keeling in the first quarter that put the Green team ahead 10-0 at the 3:12 mark.

Projected starting quarterback Dennis Dixon, also a senior, completed 9-of-18 attempts for 116 yards. His only drive that resulted in points was his last, when a 47-yard drive ended with a 40-yard field goal by Matt Evensen with 2:41 left in the third.

Neither quarterback threw an interception, and neither was tackled.

"Brady Leaf did what he does best, which is be cool and composed under pressure," Bellotti said. "Dennis was affected by the two-hand touch rule more than anyone because he was not down by contact and that really affected his game."

Dixon was the starter for most of last season until being benched in favor of Leaf for the final two games as the Ducks ended the year with four straight losses, including one to Brigham Young in the Las Vegas Bowl.

Dixon was back at the top of the depth chart at the start of spring camp.

"My biggest focus this spring was becoming a better leader," said Dixon, who threw for 2,143 yards, 12 touchdowns and 14 interceptions last fall.

Dixon, Brady and the rest of the offense were also forced to learn the new system brought in by Kelly Dixon's third coordinator in four years at the school this spring.

"I think it was important just getting comfortable with our new offensive coordinator," Leaf said. "The end of last season was rough and we wanted to get the bad taste out of our mouth."

Also impressive on Saturday was receiver Garren Strong, who missed most of last season with injuries.

The Ducks open the 2007 season at home against Houston on Sept. 1.
