Penn State won the opening game of the series Friday, 6-3, before the Boilermakers took a pair of seven-inning games Saturday, 6-4 and 9-3.
Stidfole's performance allowed the Lions to lead West Lafayette with a split in the four-game set.
While Stidfole made it look as though the Boilermakers were swinging sledgehammers instead of bats, it was their gloves that let them down just as much.
Three Purdue errors led to 10 unearned runs for the Lions, including five in both the third and sixth innings.
Two errors in the top of the third set up RBI hits by Derrick Barr, Mike Milliron and Lance Thompson before Matt Lewis capped off the inning with a two-run home run, his fourth of the season.
"That's what we didn't do Saturday -- capitalize," Penn State coach Robbie Wine said.
"We capitalized well today. We had [10] two-out runs, and we did a good job of taking advantage on an error or getting runners in."
Penn State scored two more in the fourth and then exploded for another five just two innings later.
Milliron started things off by reaching on an error and then stealing second.
Thompson, who was 3-for-5, knocked in Milliron for one of his two RBI with a single.
Second baseman Jim Leitgeb also had a two-run single with two outs.
Milliron finished 2-for-4, but scored four times.
Penn State tallied its 13 runs on just 14 hits, as timely hitting was a huge reason the Lions pulled to .500 in the four-game series against Purdue.
"We didn't leave too many runners on," said first baseman Scott Gummo, who finished 3-for-5 with a run and an RBI.
"Nothing really changed throughout the weekend, just the hits were finding holes this time."
Purdue center fielder Andy Dahl led off the game with a single, and the Boilermakers collected four hits in the first three innings.
Stidfole kept them off the base paths for pretty much the rest of the game, allowing only two the following six innings.
Stidfole, the reigning Big Ten Pitcher of the Week, faced only 33 batters in his nine innings while throwing 115 pitches.
He had a tougher time putting his success into words than he did putting balls past batters.
"I don't know how to explain it," Stidfole said.
"I've been putting a lot of effort into it. Whatever it is hopefully it will keep going."
Steve Cline and the Penn State baseball team cruised to an easy 13-0 victory in the finale of a four-game series against Purdue.
