Marowa's injection comes at a pivotal time for the Bill Robertson-captained Bay United who lost Ghanaian/American import striker Samuel Adjei 11 minutes into the Wellington game with a fresh hamstring tear.
While he isn't of the stocky mould of Adjei, Marowa is agile and last summer scored six goals.
"I tried to get him just after he left the Phoenix but he went to Tasman United so it worked out the way that he had wanted," said Angell of the Zimbabwe-born Marowa who arrived in New Zealand when he was 8 and in February last year earned a trial with the Kiwi A-League campaigners, thanks to Tasman player/coach Paul Ifill putting in a good word for him.
The Bay United coach said Marowa was happy to be here to rebuild his confidence after he lost his mojo following the Phoenix trials.
"He came over last week and wanted to get a feel for us and likewise me for him ... so I'm pretty comfortable he can add more value to the group."
Adjei, Angell said, was having a scan tomorrow but they were hoping his verdict would be a short-term one.
"If it's going to be any longer [than two weeks] then we won't see much of Sammy towards the end of the season so when the scan comes back it'll reveal it's not that serious."
Lamb, a teenager who is a member of the Waitakere United youth squad, recently shifted back to Taupo.
Conroy Removals Napier City Rovers defender Wilson has been training with Angell's squad this summer.
Unfortunately Bay United have lost the services of robust defender Hayden McHenery who jetted back to his hometown of Brisbane.
Auckland-born McHenery, who recently turned 21, had a great knack of turning defence into attacks with surging runs to do justice to Angell's full-press defence and then counterattacking philosophy of playing the game.
"When Hayden came originally he had indicated he would probably go back about this time so we've known about it but we were hoping he might have just adjusted his plans," said Bay United franchise general manager Shane McKenzie yesterday.
In some respects, Wilson becomes a decent insurance policy for Angell with Englishman James Hoyle likely to secure that defensive role.
"Danny brings some experience and a good cover in the back," said McKenzie of the former Blues skipper who has been in and out of the game for both clubs because of his commitment to fatherhood in the past few seasons.
McKenzie wasn't sure when the striker-cum-defender would come into Angell's reckoning but suspected he would become handy now that Bay United looked somewhat "lighter" in the back.
Fergus Neil, another Blues defender, is nursing injuries and contemplating going under the surgeon's knife after minimal involvement with the squad this summer on advice from Angell to address the issue in a bid to secure longevity in his career.
Angell said losing McHenery was a blow but accepted players tended to have certain commitments to previous clubs so the intention was always to return to Brissy.
"I think everybody knows about Hayden's qualities and his dynamics - he's got good pace, good attitude - so he'll be a big loss.
"It's great to have had him so, hopefully, from what he's done here he can take home and move forward in his career because he'll be a good acquisition for anybody."
He said McHenery needed just a bit more composure on the ball and that would come with age.
Angell said Wilson would be handy, as long as he carried on training, should injuries affect numbers.
Lamb, Angell said, had had some injury issues but had some decent dynamics so he envisaged throwing him into the mixer between this weekend and the end of the season.
Seventh-placed Bay United need to win their remaining six games if they have any hopes of making the playoffs.
