By Tony Jackson STAFF WRITER CHICAGO – Dodgers catcher Russell Martin was sent to Northwestern Memorial Hospital on Wednesday for a precautionary MRI on his left knee, which he sprained when he attempted to slide into home but was tagged out on a would-be sacrifice fly by Rafael Furcal in the eighth inning of Tuesday’s win over the Cubs. The MRI showed nothing seriously wrong with Martin, whom Manager Grady Little had intended to rest on Wednesday night anyway. Martin will be evaluated daily. “Nothing needed to be repaired,” Conte said. “The rotator cuff was perfect, which should allow him to start his rehab pretty quickly. It should be a six- to eight-week rehab. He should be fully competitive by the start of spring training.” The question now is what, if anything, that will mean to the Dodgers, who aren’t going to pick up Wolf’s $9 million club option for next season. That will make Wolf a free agent, and it isn’t clear whether the Dodgers will even offer him a major league contract. Still cloudy Infielder Tony Abreu, who was recalled for the September roster expansion, granted an interview to several reporters before the game, with Dodgers public relations director Josh Rawitch translating. But Abreu did little to clear up the mystery of whether he told club officials he was still suffering from an abdominal injury when he was optioned to triple-A Las Vegas on July 18. Abreu didn’t play for more than a month after he was sent down because he claimed he was still hurt and belonged on the major-league disabled list – where, of course, he would be collecting his major-league salary and accruing major-league service time. The problem with that argument was that Abreu had played in each of the four games prior to July 18, pinch hitting and playing several innings defensively. Still, the players’ union reportedly is considering filing a grievance on Abreu’s behalf. When Abreu initially didn’t play after being sent down, he was placed not on the minor league DL, but on the inactive list. Abreu first said he didn’t tell club officials he was hurt when he was being sent down, but he later said he did tell Little. Little later said Abreu gave no indication he was too hurt to play. Correction An article in Wednesday’s Daily Breeze stated that the Gulf Coast League Dodgers were the club’s only minor league affiliate to make the playoffs this season. In fact, the single-A Inland Empire 66ers began a California League division series against Lake Elsinore. Covering the bases Dodgers player development director DeJon Watson confirmed that Lance Parrish, the manager of the club’s single-A Great Lakes affiliate, was fired earlier this week. But Watson wouldn’t comment on the matter beyond that. … Little said right-hander Esteban Loaiza won’t start again until Tuesday night against San Diego to accommodate the return of David Wells, who will start on Saturday at San Francisco after serving a seven-game suspension handed down by the league office. … The Houston Astros have asked the Dodgers for permission to interview assistant general manager Logan White for their general manager position, a Houston source said. email@example.comWant local news?Sign up for the Localist and stay informed Something went wrong.

We just felt with the travel and everything else, we were better off getting the MRI on a weekday, when we could get it. We feel comfortable pushing him back out there.” Martin limped off the field after the play at the plate, but he remained in the game and caught the final two innings. Martin, 24, has started all but 14 of 139 games and leads NL catchers in hits, runs scored, steals, walks, batting average (.297) and on-base percentage. He has 17 homers and 81 RBIs. Wolf fine Dodgers left-hander Randy Wolf’s arthroscopic surgery showed no major damage in his shoulder. Conte said Drs. Lewis Yocum and Neal ElAttrache did a cleanup procedure on the bursa and the labrum, which had minor fraying.
