"The first quarter was tough because we didn't play well and we didn't open them up well in defence, either," Baldwin lamented.
"We didn't execute some of our systems so Palmerston North came out with a lot of confidence," he said as Perth Wildcat Nick Horvath, import Chris Hagan and Troy Mclean created havoc with 19, 18 and 17 points, respectively.
Centre Horvath registered a double-double with 14 rebounds while point guard Hagan added nine assists and four rebounds.
Baldwin lauded their interim American import, Garrius Holloman, who is replacing Marcel Jones until the latter finishes his league campaign in Romania in almost three weeks.
"I still don't know his name [Holloman] but they might want to have a rethink about him because he's a pretty useful player."
However, Kalavros immediately ruled out any chance of that happening.
"I'm a man of my word and I'll be keeping it.
"Even though he's got a contract there's no way I'll be letting Marcel go," said the man who has coached Hawks new import Darko Cohadarevic in the Greek league.
Baldwin said his troops adjusted a little in the second quarter to earn some plaudits from him for their defence.
"But we missed a lot of easy shots," said the country's most successful basketball coach who returned to the NBL after several years of plying his trade abroad following a memorable stint with the Tall Blacks.
"We were one point down with about 120 seconds remaining on the clock in the last quarter and we again missed an easy shot but we did create a lot of chances."
A philosophical Baldwin reconciled the defeat with how sometimes a season starts.
Loathe to single out players, he felt the team would bounce back and face "the reality we won't go unbeaten this season".
"It was a great game and the result didn't go our way but we're thankful we have another game in two days."
Bay swingman Brian Greene shone with 22 points, five assists and just as many rebounds while fellow import Cohadarevic added 15 points and six rebounds to the collective.
Skipper Winitana chimed in with 13 points and four assists.
A circumspect Kalavros said it was a nailbiting game "but we also got lucky".
Having made a rash of mistakes the hosts found their plan towards the end by "reacting with some maturity" in the last few seconds.
In Invercargill, the Paul Henare-coached Sharks beat Waitakere Rangers 91-74 before playing the Hawks tomorrow in Napier.
The Rangers were competitive in the first half trailing only by six, but a 14-0 run by the Sharks to start the third quarter pushed their lead up to as many as 22.
Waitakere managed to close within 13 at the end of the third, but behind last year's rookie of the year Reuben Te Rangi (20 points) the Sharks would be too strong.
Americans Kevin Braswell and Brian Conklin each added 17 points. Point guard Luke Martin made a welcomed return to Southland collecting 11 points and seven assists.
