ARLINGTON, Texas — OF Desmond Jennings wasn't too concerned with what he did Friday in his first game with the Rays since late April. He was just happy that his left knee was feeling good and he could be back playing with his teammates."I feel good, I'm fresh and that's it. I'm just anxious and ready to play some baseball," Jennings said. "Just come back and not try and do too much and just play the game."Jennings started in leftfield and batted sixth Friday, singling in a run in his first at-bat to start a 3-for-4 night."Very promising,'' manager Kevin Cash said. "He looked really good, his at-bats were good, he squared the ball up. It was nice to see. He's going to help us a lot over the next two months.''Cash said the Rays will be a little cautious in using Jennings, checking with him after each game to see how he is feeling, but welcome what he can do."I think we're adding another side to our offense with a guy that can hit for some power and also has a lot of speed on the bases,'' Cash said.Jennings hadn't played since April 25, sidelined by a knee issue that, after a frustrating lack of progress in rehab and a second opinion, resulted in June 10 arthroscopic surgery on the plica band around his kneecap. He is wearing a nylon wrap on the line that supports his kneecap."It was a great feeling, just knowing that something actually was there and actually could be fixed and that it got taken care of," Jennings said. SMYLY A GO: The Rays made official that LHP Drew Smyly will return from the disabled list and start Sunday. He had been on the DL since May with shoulder issues, including a torn labrum."We're excited to have him back," Cash said. "It's been a long season for him, just like Des. We know if these guys are right they're both very capable of providing a pretty big boost."The Rays will have to make room for Smyly, with RHP Kirby Yates seemingly most likely to be sent down. Another option would be sending rookie INF Richie Shaffer back to Triple-A until Sept. 1. The Rays will also have to drop a player off the 40-man roster, or put injured minor-league LHP Grayson Garvin on the big-league roster and then the 60-day DL. NOT-SO-MINOR MATTERS: Former Red Sox pitching coach Juan Nieves was hired as a minor-league pitching consultant. Nieves, 50, was fired in May, a month into his third season with the Red Sox. He pitched three seasons with the Brewers and had spent 14 years in the White Sox organization, the last five as bullpen coach. "He brings great experience to an already great group of pitching instructors," farm director Mitch Lukevics said. … Minor-league medical coordinator Joe Benge was named tops in his field by the Professional Baseball Athletic Trainers Society. ARCHED UP: RHP Chris Archer and Rangers RHP Yovani Gallardo spent about 30 minutes answering questions from the 13- to 18-year-olds playing in the RBI World Series, including a Bradenton team. Archer has spoken to several groups from the Reviving Baseball in the Inner cities program during the season."I'm happy to be part of RBI because they're not trying to just develop baseball players, they're trying to develop young men," he said. MISCELLANY: SS Asdrubal Cabrera continued his sizzling hitting, going 3-for-4 to make it nine multi-hit games in his past 10 and a .500 average (27-for-54) since his return from the DL. … The Rays took batting practice in shorts and T-shirts to combat the Texas heat; first-pitch temperature was 94. … Cash was stunned by the news that Red Sox manager John Farrell , a good friend, has lymphoma: "Knowing him, I'm sure, he's a pretty strong guy that he'll get through this." … Activating Jennings from the 60-day DL was the Rays' 110th roster move since opening day. … Cash said the Rangers could have some advantage in the knowledge former Rays catcher Bobby Wilson has of the pitching staff, and Texas manager Jeff Bannister concurred.
