Dylan Grabowski's heroics catapulted No. 8 Penn-Trafford into the WPIAL Class 5A quarterfinals as the Warriors notched a 4-3 first round victory over No. 9 Hampton at West Mifflin.

Thomas Jefferson 14 Greater Latrobe 7 (Class 5A)

Things looked mighty good for fifth-seeded Greater Latrobe early in its WPIAL Class 5A first round playoff contest against No. 12 Thomas Jefferson at Hempfield. The Wildcats had scored a run in the first inning then added five additional tallies in the second inning to go in front 6-0. But Thomas Jefferson immediately tied the game by posting six runs in the third and went on to outscore Greater Latrobe 8-1 the rest of the way to capture a 14-7 victory. GL trailed by just two, 9-7, after five innings but the Jaguars plated four runs in the top of the sixth inning to put the game away. Vinny Amatucci and Logan Bradish each had three hits with Bradish driving in three runs for the Wildcats (12-8). Logan Short went 2-for-4 with two RBIs. Thomas Jefferson pitcher Brady Haberman was knocked out of the game in the second inning but reliever McClain Flinn put out the fire allowing only one run on four hits over the remaining 5 1/3 innings. The Jaguars (14-6) will next meet No. 13 Chartiers Valley in the quarterfinals. The Colts upset fourth-seeded Mars 8-6 in the first round.

South Fayette 10 Franklin Regional 0 (Class 5A)

Franklin Regional's title defense ended in the first round of the WPIAL Class 5A playoffs on Tuesday night. The defending district champions were shut down in a 10-0, five-inning loss to No. 7 South Fayette at Burkett Park in McKees Rocks. Lions' pitcher Tyler Pitzer, who recently returned from shoulder soreness, did not allow a single base runner in five perfect innings. He struck out nine of the 15 batters he faced. Caden Smith, a three-sport athlete who will play football at Pitt next fall, started on the mound for No. 10 Franklin Regional but lasted just 2 1/3 innings after surrendering eight runs, seven of them earned. The Panthers finish the season with an 11-6 record. South Fayette (15-4-1) will face second-seeded Bethel Park in the quarterfinals. The Blackhawks narrowly avoided Gateway's upset bid, beating the Gators 6-5 on Tuesday.

New Brighton 2 Derry Area 1 (Class 3A)

Derry Area was limited to just three hits in a 2-1 loss to New Brighton in the WPIAL Class 3A first round clash at Highlands High School. In a rematch of last year’s first-round playoff tilt, the Lions exacted revenge, as pitcher Bobby Budacki threw a complete game. He outdueled Derry Area (11-7) pitcher Ryan Hood, who went the distance, allowing just five hits while striking out nine. The No. 7 Lions (10-9) opened the scoring in the bottom of the first, as the initial three batters all reached, and a fielder’s choice plated a run. Hood escaped further damage, however, until the fifth, when his throwing error allowed New Brighton to plate a second run. Tenth-seeded Derry Area’s lone run came in the sixth inning, as Jonathan Hugus led off with a double and later scored when Brady Angus was caught in a rundown on a steal attempt. New Brighton advances to Thursday’s quarterfinals round to face South Park.

Yough 7 Mount Pleasant 6 - 8 innings (Class 3A)

Yough scored seven unanswered runs, including a walk-off single by Allen Novacek that scored Korvyn Johnson in the bottom of the eighth inning to claim a 7-6 win against Mount Pleasant Area in the WPIAL Class 3A first round at Hempfield Area High School. The fifth-seeded Cougars (11-7) trailed the No. 12 Vikings 6-0 heading to the bottom of the third, but Yough scored twice in that frame without a hit. In the fourth inning, the Cougars compiled five consecutive hits and deadlocked the contest. The Vikings (9-8) opened the scoring with a run in the first, added a pair more in the second, and notched three runs in the third stanza. The Cougars advance to the quarterfinals, and will face Keystone Oaks on Thursday.

Avonworth 10 Southmoreland 0 (Class 3A)

Mason Horwat and Colin Crawford combined to throw a five-inning no-hitter in leading No. 3 Avonworth to a 10-0 triumph over No. 14 Southmoreland in a WPIAL Class 3A first round game at Highlands. The lone baserunner for the Scotties came in the fourth inning as Brok Potoka drew a one-out walk. Horwat induced the next batter, Ty Keffer, to ground into a double play to end the inning. Keffer and Anthony Govern each saw time on the mound for Southmoreland which finishes the season with a 7-9 record. The Antelopes (14-7) will play East Allegheny in the quarterfinals.

Greensburg Central Catholic 9 Leechburg 4 (Class 1A)

Greensburg Central Catholic scored four times in the second inning, capitalizing on three Leechburg errors, and the Centurions never relinquished the lead in securing a 9-4 victory against the Blue Devils in the WPIAL Class 1A first round matchup at Plum High School. Senior pitcher Zach David earned the victory on the bump for No. 8 GCC (9-7) in his first start of the season after recovering from an arm injury. He worked five innings, permitting three runs on five hits, while he added a pair of doubles at the plate. John Tropeano, Ryan Appleby, and Brody Bothell added RBI hits for the Centurions. Matt Curfman provided three hits for the No. 9 Blue Devils (7-6). The Centurions will face top-seeded Eden Christian Academy in the quarterfinals on Thursday.
