PULLMAN - Washington State coach Mike Leach didn't take much pleasure in his first victory as coach of the Cougars.

Washington State barely hung on to beat Eastern Washington 24-20 on Saturday in Leach's home debut, as the Cougars had to knock down a final pass in the end zone to ensure the victory.

"We've just got to get better," Leach said. "We had lapses in focus and tempo."

Washington State (1-1), which lost at BYU in the season opener, also unveiled a $65 million upgrade of Martin Stadium in front of the first sellout crowd here since 2007.

Eastern Washington (1-1), an FCS power coming off a victory over Idaho of the FBS, kept it close behind a pair of touchdown receptions by Brandon Kaufman.

Washington State took a 10-point lead late in the second quarter but was held scoreless in the second half to give Eastern a chance at an upset.

"We've got to be a team that puts them away," Leach said. "We let them off the hook a few times.

"Eastern Washington deserves a lot of credit," Leach added.

This was the first meeting since 1908 between the two programs, located 60 miles apart.

Eastern players expressed disappointment they did not beat a second FBS team in the same season.

"We knew we could play with these guys," said EWU defensive back T.J. Lee. "We are very sad we didn't get the win."

Eastern coach Beau Baldwin was proud of the way his team came back.

"I know I have a ball club that no matter what the situation, we aren't quitting," Baldwin said. "We are going to fight to be there in the end."

Washington State scored first when Jeff Tuel connected with Isiah Myers in the back of the end zone on a 2-yard scoring pass with 5:42 left in the first quarter. It was their first touchdown of the season after being held to two field goals by BYU.

Eastern replied on the next series when quarterback Kyle Padron hit Kaufman with a 93-yard touchdown pass to tie the score. But Washington State drove 75 yards on its next series, with Carl Winston rushing over from the 1 to take a 14-7 lead. Winston's 27-yard run was the key play of the drive.

Eastern Washington drove 80 yards on its next series, half coming on a reception by Zack Gehring, before Jordan Talley ran over from the 5 to tie the score at 14 early in the second quarter.

Washington State's Cyrus Coen intercepted a scrambling Padron and ran the ball down to Eastern's 17. On the first play, Tuel passed 17 yards to Myers for a touchdown that put WSU up 21-14.

A 60-yard field goal by WSU's Andrew Furney as time expired gave the Cougars a 24-14 halftime lead. It was the second-longest field goal in team history after Jason Hanson's 62-yarder against UNLV in 1991.

The third quarter was scoreless.

Washington State had first-and-goal on the EWU 2 in the fourth quarter, but Teondray Caldwell fumbled on a run and EWU's Allen Brown recovered. The Eagles went on a penalty-filled 99-yard drive that ended with a 17-yard touchdown pass from Padron to Kaufman. The extra point was blocked to leave WSU with a 24-20 lead with 2:17 remaining.

Washington State recovered the onside kick, had two touchdown plays called back because of penalties, and had to punt.

Eastern got a last chance with 1:29 left from its 17, and moved down to WSU's 32. Padron's pass to Kaufman in the end zone was batted down.

Washington State has never lost in 17 games against teams from the FCS. Eastern Washington is 8-21 against FBS teams.

Tuel completed 20 of 26 passes for 171 yards and two touchdowns and was not intercepted, before leaving the game with an injury late in the second half. Winston and Caldwell gained 67 and 46 yards on the ground to provide a balanced attack.

Padron completed 26 of 54 passes for 379 yards, with two touchdowns and two interceptions.
