NEW YORK — Yankees ace Chien-Ming Wang is expected to be sidelined until at least September after injuring his foot running the bases, prompting club co-chairman Hank Steinbrenner to chastise the National League on Monday for playing without a designated hitter.
“My only message is simple. The National League needs to join the 21st century,” he said.
Wang (8-2, 4.07 ERA) partially tore a tendon and sprained his right foot Sunday during the Yankees’ 13-0 interleague win at Houston.
Footnotes.
David Ortiz had the cast removed from his left wrist and replaced by a removable splint, an encouraging sign for Boston’s big slugger, who has a partial tear of the sheath.
• Boston left fielder Manny Ramirez returned to the lineup after missing two games with a sore hamstring. First baseman Kevin Youkilis didn’t start because of muscle spasms in his back.
• Seattle fired general manager Bill Bavasi. Vice president and associate GM Lee Pelekoudas will take his place.
