ST. PETERSBURG — OF Desmond Jennings will miss at least another two weeks as the Rays put him back on the disabled list due to continued problems with his left knee. Now the question is whether he will play again in what already has been a lost season."Just from talking to him the last couple days I know he's frustrated with it and there's just some uncertainty," manager Kevin Cash said. "So I think our best thought was let's get him off his feet and see if 15 days of rest can help."OF Joey Butler was called up from Triple-A Durham, chosen over INF Richie Shaffer , who is expected back in September.Jennings has played only 28 games this season, spending 3½ months on the disabled list due to what was diagnosed as left knee bursitis and led to arthroscopic surgery in June.Jennings, making $3.1 million, played 10 games after his return, hitting .353 with one homer and five RBIs, before being sidelined again on Tuesday. The new issue is being called a bruise, stemming a slide into second on Saturday, and it is not clear if or how it is related. Jennings was again not available for comment."It's been a rough year for him," Cash said. "I think Des has gone about it the right way. He's done everything he could to get back. He goes and has the procedure done with the hope that was going to alleviate all of the issue. Obviously it has not. Maybe this is something he is going to have to manage throughout the rest of the year and an offseason will really help." LONEY SITS OUT: 1B James Loney dropped his appeal and served his one-game suspension.The decision was based on timing, coinciding with the Twins starting a lefty meaning Loney was not likely to be in the lineup anyway. The official explanation was that Loney didn't want to take the chance on going through with the hearing and MLB dictate what game he missed. "You might as well just take it on your own terms," he said. BUTLER DID IT: After an impressive start with the Rays, Butler hit only .151 over his final 30 games as he was reduced to part-time duty and was sent down Aug. 12. But a stint playing regularly with the Bulls helped, as he hit .368 with four homers in nine games. "I think just the reps and seeing pitches on a regular basis helped a lot," he said.Butler showed it Thursday, rapping two hits, knocking in the tying run. His experience in the outfield worked in his favor, plus the thinking that Shaffer, hitting .366-3-11 in nine games for Durham since he was sent down, will benefit from regular at-bats until a recall.HEY, ZO!: INF/OF Ben Zobrist tonight makes his first visit back to the Trop since being traded in January following a nine-year career in which he ranked among the Rays' all-time leaders in games, hits, runs and RBI."He should be celebrated as high as anybody that's ever come back and played against us," 3B Evan Longoria said. "He's a significant figure in what we did from 2008 until his last year here. He had a huge impact here obviously not only on the field but in the community and in the eyes of the public. He's good natured and he was one of the best teammates I ever played with. … I'm hoping we have a good crowd that's really responsive and really appreciative of the things that he did for us here."There will be a pregame tribute, and Zobrist's wife, Julianna , will sing the anthem. The Rays suggest fans be in their seats by 6:55 p.m. SOUZA HANDY: OF Steven Souza Jr. said a Thursday X-ray of the left hand fractured Aug. 1 was good and he was cleared to start swinging a light bat, with a plan to get into rehab games during the minor-league playoffs and return mid-September. MISCELLANY: C J.P. Arencibia drew praise from Cash for his work behind the plate in his first start; Rene Rivera may play all three games against the Royals based on his ability to shut down their running game. … The Rays last four wins have been by one run. … Thursday attendance was 9,375, making the total for the three-game series 28,212. … The Rays have won 17 of their last 23 games against lefty starters. … LHP Blake Snell , who has a dazzling 13-4, 1.29 ERA between advanced Class A Charlotte, Double-A Montgomery and Triple-A Durham, is among five finalists for USA Today's minor-league player of the year award, with a fan vote component via usatoday.com.
