Wang, the favorite to become the Nationals' fifth starter, left in the third inning of Washington's 8-5 loss to the New York Yankees on Thursday with a strained left hamstring.
Fielding Russell Martin's grounder near first base, Wang stumbled then fell. As he was falling over first base, his leg went up in the air and was brushed by Martin as he ran through the base.
Manager Davey Johnson said Wang would undergo more tests to determine the severity of the injury.
PHILLIES: Roy Halladay is just fine despite ugly numbers.
The two-time Cy Young Award winner said he’s not injured and criticized a report suggesting something might be wrong with him because he’s struggled in spring training.
Halladay got rocked for five runs and seven hits before getting yanked in the third inning of Philadelphia’s loss to Minnesota on Wednesday. A report later surfaced quoting two unidentified scouts expressing concern that Halladay’s velocity is down and his sharpness is off.
“Poor reporting on the extreme end of poor reporting,” Halladay said. “It couldn’t be further from the truth.”
Halladay, an eight-time All-Star, has a 10.56 ERA in three spring starts. He acknowledged his velocity is down, but isn’t worried because it’s still early.
• Spring training invitees Juan Pierre and Joel Pineiro helped their cases for making the Phillies, with solid starts for a Philadelphia split squad in a 6-6 tie with Tampa Bay.
MARLINS: Jose Reyes stepped into the on-deck circle, turned toward the New York Mets’ dugout and bowed. Hard feelings, nowhere to be found.
The Miami Marlins shortstop faced his former team for the first time Thursday, shaking hands and offering hugs before the game with former teammates. Miami won 3-1.
ROYALS: Signed shortstop Alcides Escobar to a $10.5 million, four-year contract extension that includes two option years that could drive the value to $21.75 million.
MARINERS: Kevin Millwood had a strong outing in his attempt to make Seattle’s roster. The veteran pitched four scoreless innings in his most effective start of the spring and the Mariners beat Kansas City 6-2.
