There wasn’t much more Jacob Thomas could do as he led fifth-ranked Messalonskee of Oakland to its 6-2 Class A North baseball quarterfinal victory over No. 4 Brewer on Tuesday afternoon on Mahaney Diamond at the University of Maine in Orono. The senior left-hander silenced Brewer’s bats with a pitching philosophy based on changing speeds and mixing pitches, tossing a complete-game four-hitter that required just 72 pitches — 58 that were strikes. “He’s a real old-school pitcher,” Messalonskee coach Eric Palin said.
