"That's when I got mixed emotions," Larkin said. "I was happy. I was nervous. A lot was going through my mind. Once I got on the mound, I was ready."
The 6-foot, 160-pounder mixed a fastball, curveball, and change-up in allowing four hits and walking three. He threw 90 pitches, 54 for strikes.
Brobst went with Larkin partly because junior righthander Cam Simmons, who took over in the seventh and notched the save, experienced some arm issues after closing Monday's 2-1 victory over Parkland. Junior righthander Bret Clarke went six innings in Monday's win over Parkland.
"When Cam was not 100 percent, we had to piece things together," Brobst said. "We made it as simple for Conor as we could. We said, 'You throw the ball over the plate, and we'll do the rest.' "
In beating Methacton for the third time this season, the Rams (20-7) earned a berth in Monday's state semifinals, at a site and time to be determined, against District 12 champion La Salle.
Larkin's brothers, Sean and Dan, play for Cedarville University in Ohio.
Taking advantage of a leadoff walk, the Warriors (22-7) gained a 1-0 lead in the visiting second on Erik Marburger's RBI single.
Held to three hits in the first four innings by senior righthander John Wiedmayer, the Rams struck for three runs in the fifth, aided by a throwing error on a sacrifice-bunt play. The highlight was Ryan Markey's two-run single to left field.
After making it 3-2 in the sixth, Methacton threatened in its final at-bat.
But after Tim Carfrey drew a two-out walk and brazenly stole second and third, Simmons clinched the win with a strikeout.
