Of the group, the Orioles are most concerned with Givens, who is a big part of their bullpen. The righty, playing in his first World Baseball Classic, will have to be monitored, innings-wise, during Spring Training to ensure he stays healthy and productive through the year.
Xu is listed as a member of the designated pitcher pool (DPP). Each team has the option of using the DPP, which works like this: A team can use up to 10 designated pitchers but can't have more than two on its active roster at a time. Those active DPs can be replaced at the beginning of each of the next two rounds, but only by another DP. Once a DP has been replaced, he cannot return to the active roster for a subsequent round. 

Using Team USA as an example, Danny Duffy and Tanner Roark are the active DPs for the first round of pool play, so they can be replaced on the roster before the second round or the championship round, but only by one of the team's other DPs. And if a DP joins for the second round, he can be replaced for the championship round.
