With a bundle of key players on the disabled list, Mets general manager Sandy Alderson said Friday the team is making changes to the way it handles injuries. [...] Syndergaard partially tore the latissimus dorsi behind his right arm April 30, a few days after refusing an MRI exam while dealing with biceps and shoulder discomfort. Shortstop Asdrubal Cabrera, catcher Travis d’Arnaud, left-hander Steven Matz and right-hander Seth Lugo also are on the 10-day DL, and third baseman David Wright and reliever Jeurys Familia are on the 60-day DL. Designated hitter Albert Pujols was out of the Angels’ starting lineup Friday because of a sore right hamstring.
