Manager Buck Showalter has said that he's evaluating everyone now for next year, but said he can see what Uehara can bring to a team.
"I don't throw out what's gone on here for a year and three-quarters-ish," Showalter said. "I know what I've seen since I've been here. I can see why he was somebody that was coveted to bring in. Keeping him healthy, I know, has been a challenge, but it's pretty obvious when he's healthy that he can make a really good contribution."
Uehara closed out Thursday's 4-0 victory over the Rangers with a scoreless ninth inning after Brian Matusz blanked Texas through eight.
In Monday's win over the Mariners, Uehara struck out a season-best four batters in 1 1/3 scoreless innings. He's held right-handed hitters to a .183 average so far this season, but has two stints on the disabled list.
