Unable to apply parameterised curried function

I have a function, that has the following definition: 

def expectMsgPF[T](max: Duration = Duration.Undefined, hint: String = "")(f: PartialFunction[Any, T]): T = {

When I call it as follows: 

val res1 = listener1.expectMsgPF(1.second)

Is res1 a function?

I would like to write as follow: 

 val res1 = listener1.expectMsgPF(1.second) _
 val res2 = listener2.expectMsgPF(1.second)
 Then("it should contain `Kafka and SAP are offline`")
 res1 {
    case status: ServerStatus =>
    status.health should be(ServersOffline)
  }

But it does not work.

To make res1 { case status: ServerStatus => status.health should be(ServersOffline) } work, try helping the compiler out by providing type parameter T to expectMsgPF[T] like so

val res1 = listener1.expectMsgPF[Assertion](1.second) _

This makes res1 indeed a function of the type 

PartialFunction[Any, Assertion] => Assertion
