WASHINGTON -- The New York Mets again get to face a phenom in his major league debut on Tuesday.
With Stephen Strasburg landing on the disabled list with an upper-back strain, the Washington Nationals will promote their top pitching prospect, Lucas Giolito, from Double-A Harrisburg to start opposite Matt Harvey at 7:05 p.m. ET at Nationals Park.
"He pitched a game against us in spring training, so we've got a little background," Terry Collins said.
The Mets have faced their share of top pitching prospects in their major league debuts this season.
