Added were Jason Hammel, Wei-Yin Chen and Miguel Gonzalez, who are expected to start Games 1, 2 and 3, respectively. Chris Tillman, who was also added, could be a candidate to make a start later in the series. Manager Buck Showalter said Tillman, Gonzalez and lefty Joe Saunders will be available out of the bullpen in Game 1.
Removed from the roster were pitchers Jake Arrieta, Zach Britton and Steve Johnson. Britton was sent to the Minor League facility in Sarasota, Fla., to continue pitching, in case he is needed later in this series or beyond. He is scheduled to throw a simulated game on Tuesday. Outfielder Xavier Avery will work out in Sarasota as a roster standby.
If Hammel, who is dealing with knee problems, were to suffer another injury on Sunday, the club could fill his roster spot only with another pitcher.
"Every one of those guys, as I told them today, has to have the mindset that they're playing tomorrow, because they could be," Showalter said. "They could be playing tomorrow."
The full 25-man roster is as follows:
Infielders/outfielders/designated hitters: Robert Andino, Endy Chavez, Chris Davis, Ryan Flaherty, Lew Ford, J.J. Hardy, Adam Jones, Manny Machado, Nate McLouth, Mark Reynolds, Jim Thome.
Catchers: Taylor Teagarden, Matt Wieters.
Pitchers: Luis Ayala, Chen, Gonzalez, Hammel, Tommy Hunter, Jim Johnson, Brian Matusz, Darren O'Day, Troy Patton, Joe Saunders, Pedro Strop, Tillman.
