The Clippers, winners of back-to-back state championships, finally came to life in the sixth, scoring two runs to make it 6-3. Down to its final three outs, Bennett scored two more in the bottom of the seventh, including a double by Mike Jean Charles and a triple by Josh Wyatt to make it a one-run game, but Reservoir got the final out on a fly ball to left fielder Paul Quattrone.
The Gators will now visit Stephen Decatur, a 5-4 winner over River Hill, on Friday at 4 p.m. for the regional championship. Reservoir has never won a regional title.
MIAA B Conference
Glenelg Country 6, St. Marys 4
With its 6-4 win over top-seeded St. Marys on May 15 at Joe Cannon Stadium, Glenelg Country School avenged the loss which prevented it from winning the regular season MIAA B Conference title, and earned the Dragons a trip to the B Conference championship game on Sunday, May 19 at 1:30 against St. Marys or Boys Latin.
St Marys (25-2) held a 4-1 lead after five innings, but Glenelg Country (18-2) scored four runs in the top of the sixth to go ahead, 6-5. Colby Manekin, Will Seiferth and Jack Dougherty (RBI) started the inning with back-to-back-to-back base hits, and then Max Godwin hit an RBI ground out. Dylan Farnella then beat out an infield single, and Matt Sheehan drove in Dougherty with another ground out.
The Dragons loaded the bases on a Logan Smith single and a Cameron Clifton walk, chasing St. Marys starting pitcher Chase Gorski. Leadoff man Miguel Flores was then hit by the first pitch to drive in the go-ahead run, giving Dragons starting pitcher Jake Figueroa (8 hits, 4 runs, 3 strikeouts) the victory.
Manekin earned the save by pitching the last 1 2/3 innings, and was aided by a diving catch by shortstop Dylan Farnella in the last inning.
Flores, Manekin, Seiferth and Sheehan each had two hits for the Dragons, and Ryan Davis had two hits for St. Marys.
