There’s still no way to know how this is going to end, if Alex Rodriguez can still play major league baseball or at an elite level after undergoing a second hip surgery in January. And the possibility Major League Baseball will suspend him in the Biogenesis mess remains real. Rodriguez has denied any involvement with the South Florida anti-aging clinic. Yet, Rodriguez’s attempt to get back to The Bronx moves forward tonight, when he begins a rehab assignment with Single-A Charleston (S.C.). At least for now, the third baseman and the Yankees appear to be in agreement on something. Rodriguez was cleared yesterday to begin a 20-day rehab assignment and, following a conference call with team officials, the Yankees made the announcement, meaning the 38-year-old is finally ready to take the field again. He is scheduled to play a minimum of three innings. “I’m actually very excited,” Rodriguez said as he drove out of the Yankees’ minor league complex in Tampa. “It will be the first game I’ve played in, maybe, over eight months. It’s been a long time. And it will be great to suit up again. It gets me one step closer to helping my team win in New York.’’ The announcement came a week after Rodriguez helped spark another controversy, when he said on his Twitter account he had been cleared to play in games by the surgeon who performed his second hip surgery, Dr. Bryan Kelly. General manager Brian Cashman erupted at the news and told the third baseman to “shut the f - - - up. When the Yankees want to announce something, [we will].” That finally happened yesterday. “We fully expect him to take the 20 days,” Cashman said by phone, adding the team’s woeful performance at third base would have no impact on Rodriguez’s return. “You can’t rush health.” When asked if the Yankees’ issues were behind them, the GM said: “We’ve announced his rehab schedule and we’re ready to get started. That’s all we can do.” Reaction in the Yankees’ clubhouse at Target Field was about what you would expect: A step forward.
