The Miami Heat fought their way out of the play-in tournament and reached the NBA Finals last season. They would like to avoid that extra step this spring, which is why their weekend visit to Detroit could prove pivotal.The Heat will be looking to snap a four-game losing streak when they face the Pistons on Friday and will remain in the Motor City for a Sunday afternoon tilt.The Heat (35-30) are currently in eighth place in the Eastern Conference standings and need to finish in the top six to avoid the play-in tournament.In their latest defeat, the Heat trailed the red-hot Denver Nuggets by a point entering the fourth quarter and were outscored 28-17 over the final 12 minutes in the 100-88 loss.”When the (Nuggets) want to put on the jets, they’ve been able to leave teams behind in the dust and that’s what it felt like (Wednesday),” Heat coach Erik Spoelstra said of the team’s opponent in last season’s NBA Finals. “It felt like they just flipped a switch in those last four minutes.”Miami shot 42.5 percent from the field in the latest meeting and only knocked down five 3-pointers in 21 attempts. The Heat are 2-12 when failing to reach the 100-point mark.”Clearly it was a struggle for us to score,” Spoelstra said. “We had moments and that’s fine actually if we could have kept it in the mud. But they had their burst and we stayed where we were and that was basically the game.”Miami has won its first two meetings with Detroit this season. The Heat eked out a 103-102 season-opening victory in October. The second meeting came earlier this month, when they posted a 118-110 triumph on March 5 as Jimmy Butler had 26 points and eight assists.During the current losing streak, Butler has been held to 18.0 points per game with only two made 3-pointers in 11 attempts.The Heat are not expected to have Tyler Herro available this weekend. He’s been sidelined the past nine games due to a foot injury.”He’s making progress,” Spoelstra said.
