Ausmus said earlier this weekend that Soria still feels some soreness in the oblique near the end of his sessions, but that he's progressing further and further out in his throwing before he feels it. It's not full health, but the Tigers are taking it as progress.
The Tigers have been trying to fill Soria's role mainly with Jim Johnson, signed earlier in the month after being released by Oakland. The former O's and A's closer entered Saturday's nightcap in the eighth inning with a 5-0 lead following an Adam Eaton leadoff single off Blaine Hardy, but loaded the bases with an Alexei Ramirez double and Jose Abreu walk. All four runs scored, three of them on Dayan Viciedo's home run off of Joba Chamberlain.
Before that, the Tigers' bullpen had given up a lone earned run over its previous 19 1/3 innings, covering a seven-game stretch.
