The Malaysian outfit's return to league action following the mid-season break was delayed following their participation in the AFC U-22 Asian Cup qualifiers in Myanmar.
However, they showed no signs of fatigue at the Queenstown Stadium on Friday as they cruised to a comfortable win courtesy of goals from Ahmad Hazwan and D. Saarvindran.
While he was pleased with the way his side controlled the game, Ong believed they could have won by a bigger margin had his players managed to convert their dominance into goals.
"We were the better team tonight [Friday]," the former Malaysia international said after the game. "We were always in control.
"However, we had so many chances that we should have converted - Thamil [Arasu] and Syahrul [Azwari] both missed excellent opportunities.
"Had we scored those, it would have been far more comfortable for us."
Nonetheless, Ong insists the only thing that matters at the end of the day is the three points, which sees them move just four points behind leaders Albirex Niigata, with two games in hand.
"The most important thing is that we collected the three points," he added. "It keeps us within touching distance of the teams at the top.
"Still, we are not thinking about our title chances. My pre-season target was to finish in the top five and we're going to take one game at a time."
Ong was also effusive in his praise when asked by ESPNSTAR.com about the performance of midfield general Gary Robbat, a player he believes fully deserves his recent call-up to the Malaysia national team.
"Gary was tremendous today [Friday]," Ong said. "He showed why he has been called up to the national side.
"It will be another step for him, getting the exposure of playing with and against good players."
Tanjong Pagar assistant coach D. Tokijan admitted the Jaguars had only themselves to blame for the goals they conceded.
"We knew it was going to be a tough game," he revealed. "We tried to keep things compact but one lapse in defence cost us the first goal.
"As for the second goal, we could also have played it safe and kicked the ball out but instead, we allowed them to win back possession and score."
Friday's match also saw Tanjong Pagar hand debuts to mid-season signings Carlos Delgado and Anthony Aymard, and Tokijan admitted both players are still settling in at the club.
"We are still struggling for rhythm in the middle," the former Singapore international admitted. "Carlos and Anthony are both new to the side.
"We did try to get the ball inside the box whenever we could and had a number of chances, but we couldn't convert them.
"We're still working on our link play, from defence to midfield and then from midfield to attack.
"But when we do manage to get that right, I think we'll be alright."
Tanjong Pagar remain four points above basement club Geylang United and 12th-placed Woodlands Wellington.
