The Falcons (14-5, 6-2 in league), who sit in second place in league behind undefeated Arcadia, never relinquished control of the game after taking a 4-0 lead in the top of the first inning.
Elliott Surrey (two for two) got the ball rolling with a one-out triple and next batter Joe Sedano walked to put runners at the corners for Mulcahey, who doubled into the gap in right-center field to plate two runs.
Kyle Pomeroy reached on an error with Mulcahey advancing to third base and Mulcahey would make it 3-0 by scoring on a wild pitch to Nate Rousey. Pomeroy, who finished one for two and drove in three runs, would score the final run of the frame on a groundout by Troy Prasertsit.
“We just needed to score runs,” said Mulcahey, who drove in three runs and scored twice. “That’s our biggest challenge, to score and get ahead [early], because we’re always good at defense and we can hold them down.”
Glendale showed some fight in the bottom of the second when Zachary Fields led off with triple. He would score immediately on a groundout by Wesley Tinoco, but the Nitros (1-8, 1-7) could only muster a single and a walk from that point on.
“We got on [Mulcahey] in the beginning, but it looked like he got even more comfortable after not letting us score again,” Osuna said. “He looked like he was getting better as the game was going.”
Conversely, the Falcons continued to settle in at the plate against Glendale’s Jason Marquez, normally a catcher, who was forced into an emergency start on the mound by a rash of injuries to the team’s pitching staff.
Pomeroy singled home Sedano and Mulcahey, who had walked and doubled, respectively, in the third inning and Prasertsit (one for three with two RBIs) doubled with two outs to plate Pomeroy for a 7-1 lead.
Crescenta Valley blew the game open in the top of the fourth with five more runs on four hits and two errors.
Jason Kim reached on an error to lead off the frame and scored when Cole Currie’s bloop single to right field was misplayed for another error.
Currie scored from second base on a single by Surrey and Surrey was able to score on Mulcahey’s third double of the day two batters later.
Rousey capped the scoring with a one-out single to left field to plate Mulcahey.
