Seranthony Domínguezis rehabbing in Lehigh Valley (Cheryl Pursell) Phillies reliever Seranthony Domínguezmay have been charged with three earned runs in less than an inning pitched on Wednesday night, but his rehab appearance was still a success in some ways. The right-hander allowed two walks and a single as he recorded just one out in the fourth inning for the Triple-A Lehigh Valley IronPigs in a 10-3 loss to Scranton/Wilkes-Barre at Coca-Cola Park. It was certainly not pretty, but it was still progress; Domínguezwas throwing on back-to-back nights for the first time since beginning to pitch again in the minors earlier this month. The 26-year-old was pulled after throwing 21 pitches, and all three runners that reached base against him came home to score. His short outing came one night after his first game with the IronPigs in which he surrendered one run to score on a wild pitch, but struck out three batters in the inning. He threw 17 pitches on Tuesday. Domínguezhad at least one day of rest prior to his seven rehab appearances for High-A Jersey Shore and Double-A Reading as he works his way back after undergoing Tommy John surgery last summer. Beginning on Aug. 3, Domínguezcruised through his first three appearances for Jersey Shore, but the road has been a bit more rocky since joining the higher levels. He had just one scoreless appearance out of four in Reading. While it hasn't been without struggle, the reliever's stuff has still been improving as he goes along with his rehab. His fastball sat in the low-90s in Single-A, but touched 96 mph in his first outing in Lehigh Valley. Domínguezalso flashed a version of the pitch with hard sink, as well as his signature cutting movement in the three-strikeout appearance. His changeup also worked well that night. Domínguezclearly still has some rust to continue knocking off, but the velocity and movement starting to return has been a positive. If he can start to put together some sharper outings, perhaps the Phillies' former fireman can contribute in the majors again down the stretch.
