Eflin (knee) was placed on the 15-day DL Tuesday with patellar tendinopathy in both knees, Ryan Lawrence of The Philly Voice reports.
While it's the first report of Eflin dealing with knee issues this season, he could have been bothered by it in his past three starts as he's given up a combined 20 earned runs during that time. He'll now head to the disabled list to refresh his knees and is without a timetable to return to the big league rotation.
