PULLMAN, Washington (Ticker) -- Staying in the Top 25 is getting very scary for 25th-ranked Gonzaga.
Blake Stepp scored a career-high 34 points as Gonzaga posted a 110-104 overtime victory over Washington State, which got a career-high 42 points from Marcus Moore.
For the third straight game, the Bulldogs (5-2) were challenged by an opponent. On Monday, they needed overtime to get past Washington and three days later, they rallied from an 11-point deficit at Montana.
Stepp shot 9-of-16 from the field, including 4-of-7 from beyond the arc.
Stepp has been instrumental in lifting Gonzaga to three straight wins. Against Washington, he converted all eight free-throw attempts in overtime and three days later he combined with Kyle Bankhead to score 22 of the Bulldogs' final 25 points.
Moore, who had 32 points in the second half, added five more in overtime. Ronny Turiaf gave the Bulldogs the lead for good at 99-97 with two free throws at the 2:55 mark.
"That was a heck of a basketball game," Washington State coach Paul Graham said. "It's a shame somebody had to lose. I'm proud of our basketball team. Contrary to what anybody may think this is going to be a good team."
Graham, whose team finished 6-22 last season, has seen his team drop its last three games by a combined 13 points.
Coming off a two-point performance in Wednesday's loss at Idaho, Moore shot 15-of-29, including 9-of-15 from beyond the arc.
An extra session did not seem necessary as Gonzaga held a 68-49 lead with 12:05 remaining following a free throw by Turiaf.
But the Cougars (2-3) started to chip away and used a 24-13 run to get within 81-73 with 3:37 remaining following a layup by Justin Bellegarde.
Following the layup, Moore drilled four consecutive 3-pointers to cut the deficit to 89-87 with 47 seconds left in regulation. Shortly thereafter, Washington State got within 91-90 on a 3-pointer by Thomas Kelsati.
"I just didn't want to lose," Moore said. "We started to get momentum. We showed that we won't quit. That has been the mark of our team for a while now."
Stepp made two free throws on the other end to restore Gonzaga's three-point advantage. But after a timeout and with a defender in his face, Moore beat the buzzer with a game-tying 3-pointer from near halfcourt.
"I can't say I didn't think it wasn't coming," Gonzaga coach Mark Few said. "He already banked one in. It was a great play."
Turiaf added 21 points and Richard Fox chipped in 18 for the Bulldogs, who shot 57 percent (35-of-61) and took a 49-37 halftime lead.
Fox scored 12 of Gonzaga's first 17 points of the second half as it opened up a 64-47 lead with 14 minutes remaining.
