CARY, N.C. -- Blake Solis, Chaminade Prep's No. 9 hitter, stepped to the plate with two outs in the bottom of the seventh inning with Blake Rutherford, the No. 7 Draft prospect, on deck.
Rutherford was enjoying a 4-of-4 day for Chaminade Prep, but his Eagles trailed Walton (Ga.) High by one run with a runner on first base in the quarterfinals of the National High School Invitational.
Many in attendance at the USA Baseball National Training Center's Coleman Field were wondering if Solis could get on base to give Rutherford another at-bat.
However, Rutherford and his teammates were well aware that Solis is normally the Eagles' No. 3 hitter.
The 5-foot-9, 185-pound senior outfielder turned on an inside fastball for a walk-off home run that lifted Chaminade Prep to a 9-8 win over Walton on Thursday.
He was mobbed by teammates at home plate.
"I've never hit a walk-off," Solis said. "This was by far the craziest home run I've ever hit. I've never been involved in anything like this. This was special."
With the victory, Chaminade Prep advances to Friday's semifinals against Florence High of Alabama. The other semifinal matches Huntington Beach High (Calif.) and Allatoona High (Ga.).

Chaminade Coach Frank Mutz explained he dropped Solis to No. 9 to give him a mental break from a slump. But normally Solis sees good pitches if opponents refuse to pitch to Rutherford, who bats leadoff, and another heavy-hitter, Nick Kahle, who hits second.
"This is a young man with incredible power and a good contact hitter," Mutz said. "I think our club is going where he goes. He protects those two big bats in front of him. If they're not going to throw to them, they have to throw to him."
Solis isn't committed to a college, and Mutz said he hoped he opened some scouts' eyes.
"This is the place where kids get discovered," he said.
Solis punctuated a game that featured a matchup with two big hitters, Rutherford and Walton shortstop Carter Kieboom, MLBPipeline.com's No. 50 Draft prospect.

"(Solis) has been one of our best hitters," Rutherford said. "I knew if he got a pitch to drive he could do it. That ball was crushed. That was unbelievable."
Rutherford had three singles and a double in his 4-for-4 day and scored two runs. He was 2-of-3 in Wednesday's opening round win.
Kieboom, who is committed to Clemson, reached base in all four of his plate appearances. He walked twice, singled and reached first on an error. He finished 1-of-2 with three runs scored and an RBI.

Kahle and Walton's Jason Rooks also showed off their big bats in the game.

Kahle, a senior catcher committed to Washington, hit his second home run of the tournament. He was 2-of-4 with two runs scored and an RBI.
Rooks, a junior pitcher/outfielder who is committed to Georgia Tech, connected for a two-run homer in the first inning. He was 2-of-4 with a run scored and three RBIs.
