ANAHEIM – The Angels’ satisfaction of completing a three-game sweep of the Kansas City Royals was tempered with the concern of most likely losing closer Huston Street to the disabled list.

After the Angels’ 4-2 victory on Wednesday night, Street said and MRI showed he has a strained left oblique and his “guess” is that he would go on the disabled list.

The Angels have an off day on Thursday, so they could delay the decision a day or two.

“We’re going to take these 72 hours to really evaluate,” Street said. “The first 72 hours tells you a lot.”

If Street does go on the disabled list, Joe Smith would take over as closer. The Angels would likely call up either Al Alburquerque or Cam Bedrosian from Triple-A to take his roster spot.

“It’s never a good thing when you lose your closer, but that’s why there’s seven of us out there (in the bullpen),” said Smith, who worked the ninth for his first save on Wednesday. “Everybody has to step up and do a little more than you were asked to before. Just get ready to go. We have guys who are capable of doing it.”

Street said he had never had a strained oblique. He said he felt something while doing his throwing on Wednesday afternoon. He was just about done, on to his shortest, lightest throws of the day, when he felt something.

“I made one more throw and thought ‘there’s definitely something in there,’” Street said.

Trainers evaluated him and doctors sent him for an MRI, who confirmed the strain.

The Angels have had two other pitchers with strained obliques in the past two years.

In 2014, starter Matt Shoemaker missed three weeks, although that rehab process was perhaps accelerated because they got him back to pitch in the playoffs.

Last year, reliever Mike Morin strained his oblique in late May and was out for nearly six weeks.
