Rangers shortstop Corey Seager has appendicitis and will undergo an appendectomy. President of baseball operations Chris Young relayed the news to reporters, including Evan Grant of The Dallas Morning News, saying that Seager will be “out a period of time” but hasn’t been ruled out for the entire year. Per Jeff Wilson of DLLS Sports, infielder Dylan Moore will be added to the roster with outfielder Evan Carter moved to the 60-day injured list to open a 40-man spot.
