The Providence Bruins were ahead by a goal and appeared to be closing in on a win over the Springfield Thunderbirds with under two minutes left on Sunday before 10,113 fans at the AMP.

Then things went haywire.

Springfield’s Nikita Alexandrov, with a terrific individual rush, tied the game with 1:24 left.

Sixty-six seconds later, Alexandrov struck again. He got his stick on a shot from the point and tipped it past Brandon Bussi for the winning goal in a 3-2 decision.

It was a shocking end for Providence.

The P-Bruins finished with a 1-3 record for the week, as the absence of top players recalled by Boston or out with injuries hit home.

The week started on the road against the Charlotte Checkers with a 6-3 loss on Tuesday and a 5-2 loss on Wednesday.

Returning to Rhode Island, Providence ground out a 2-1 win over the Hartford Wolf Pack on Saturday before losing on Sunday.

Providence lost ground in the Atlantic Division standings. They are in fourth place with a record of 36-22-4-3 and 79 points. They are three points behind Charlotte and the Wilkes-Barre/Scranton Penguins. The Hershey Bears are first with 85 points.

Here’s the good, bad and ugly.

GOOD

— Providence clinched a playoff spot on Saturday night. They have missed the postseason only five times since the franchise was founded in 1992-93. The last no-playoff season was 2011-12, which was Bruce Cassidy’s first year as head coach.

— Tyler Pitlick had two very strong games.

With Providence down by a goal early in the third period on Saturday, Pitlick scored a highlight-reel goal to tie the game. He did it again on Sunday, blocking a shot and then roaring in to score an unassisted breakaway goal that tied the game.

At 33 years old, Pitlick has a career-high 19 goals. He’s had a tremendous positive impact with the P-Bruins.

— Frederic Brunet turned in an excellent game on Sunday.

— The line of Trevor Kuntar, Jaxon Nelson and Joey Abate played a terrific game on Wednesday.

— After going without a goal in his first 28 games, Nelson scored twice in three games, including the game-winner on Saturday.

— Riley Tufte outmuscled a Hartford defender, then passed to Nelson in front of the net for Saturday’s GWG.

BAD

— The P-Bruins led 2-1 going into the third period on Wednesday, then gave up four goals (two empty-netters) and lost, 5-2.

— Matt Poitras had a rough night on Wednesday. He took penalties for tripping, high-sticking and hooking.

— Daniil Misyul was minus-3 in his Providence debut on Tuesday.

— Providence was outscored by a total of 6-0 in the first period of the games on Tuesday, Wednesday, Saturday and Sunday.

— The P-Bruins penalty kill is fourth in the AHL at 85.1 percent, but gave up three goals on Wednesday.

— Providence was without captain Patrick Brown, Vinni Lettieri, Fabian Lysell, Mike Callahan and Ian Mitchell, all of whom were on recall with Boston.

UGLY

— Pick your adjective. The finish to Sunday’s game was ugly, hideous, revolting.

— Injured: John Farinacci, Billy Sweezey, Michael DiPietro
