Having spent much of his international career playing second fiddle to Neil Etheridge, Sacapano was handed the chance to be the Azkals' main man for the tournament after the Fulham man and Roland Muller were both unavailable for selection.
After an opening 2-1 defeat to Thailand in Group A, Philippines bounced back in fine fashion with wins over Vietnam and Myanmar to finish second and book their place in the last four.
Having already beaten Singapore twice this year in friendly encounters, Philippines have every chance of getting another result again on Saturday, according to Sacapano.
"We are looking for the same things we had with the group stage in Thailand, where we played as a team and fought in every game," he told ESPNSTAR.com. "So hopefully we can make the final.
"It's a big confidence boost for the team because we played Singapore two times and beat them, but every game is different.
"We won't underestimate Singapore, who are a top team, and we need to focus on the game ahead."
One of Philippines' greatest strengths in the tournament so far has been their defence, who kept clean sheets against Vietnam and Myanmar after conceding two goals against the Thais.
Having grabbed the opportunity to show his worth in the absence of Etheridge with a series of excellent displays, Sacapano is looking to repeat the feat in front of their own fans on Saturday.
"For many years I've been behind [Etheridge]," the Philippine Army custodian added. "This is now my break and it's good that I can play well.
"Our defence has made a real impact and I will try to keep a clean sheet again and be there for my team.
"It's the first time we are playing a Suzuki Cup game in Philippines and it's in the semi-finals - it's just wonderful. The fans will play a very important part."
The 31-year-old starred for the Azkals when they beat Singapore 1-0 in the last meeting between the two sides last month by making a string of fine saves, including keeping out a penalty from Shi Jiayi.
