Chris and Donnie Wright led off the inning with back-to-back doubles. Designated hitter Doug Rodio then singled in Chris Wright and Donnie Wright came home on a sacrifice fly by catcher Chris Netwall.
Yodis kicked it into cruise control the rest of the way, allowing just three hits during his final three innings. Kevin Damiano came on to pitch a perfect ninth.
Penn State baseball coach Joe Hindelang said the Lions have been waiting on this type of performance from their senior right-hander, who struggled early on this season but has pitched much better of late.
"Today this reinforced what we thought he would do," Hindelang said. "This is a tremendous shot of adrenaline for us."
The Lions broke open the game in the eighth inning. Chris Wright again led off with a double. After a Bucknell pitching change, Donnie Wright stepped into a Ben Myers fastball and launched it over the right-field fence for his sixth homer of the season.
Mike DeRenzo and Willie Melendez added RBI singles in the inning for the Lions, who have displayed noted improvement since the final game of the Delaware series.
"The last five games we played hard and we played fairly well," Hindelang said. "It's been solid defense, good pitching for the most part, and timely hitting."
The Lions got all three yesterday. Penn State tallied 12 hits and left nine Bisons standing on the bases.
Yodis, in his best outing of the season thus far, allowed just six hits, walked three and struck out five.
"I got my slider working today, and I got ahead (of the hitters) a lot more than I have been," he said. "I didn't make too many mistakes, but I didn't have my really good slider today and I wasn't dominating. I just made them put the ball in play and didn't give them too many good pitches to hit."
The Lions will head to Ann Arbor this weekend for a critical three-game conference series with Michigan.
