"If the situation calls for us to use him we are going to throw him out there," Samuel said, adding that pitch efficiency will be a factor in calling on his reliever two consecutive games. "He's up here, he has to pitch.
"If we need him to come in and get some people out, we're going to do it."
Uehara has twice landed on the disabled list this season, and struggled to pitch under the humid conditions in Texas when the O's played there in mid-May. Following May 19's appearance at Texas, Uehara was physically exhausted and didn't pitch for several days before the Orioles put him on the disabled list with a right forearm strain.
"Yes, he has a history of not pitching well or not giving you more than one inning in that kind of weather," Samuel said, as Baltimore prepares for a four-game weekend set in Arlington. "but we don't have the luxury [of not using him]."
Uehara said on Thursday that physically he feels great and would be able to pitch consecutive days if needed. Perhaps a bigger concern for the right-hander is his effectiveness since he was reinstated on June 27. Uehara has allowed three earned runs in three innings, including a pair of runs in Monday's appearance at Detroit.
"Physically, the mechanics, that's not balanced," said Uehara, who admitted this stretch has been the most frustrating for him performance-wise since signing with the O's last season. "And that part is going to lead to me being mentally imbalanced as well."
