Quick Hits: A-Rod, Desmond, Padres, Zimmermann

Alex Rodriguez's public battle with the Yankees took another turn today when the slugger denied a report that the club intends to fine him a day's pay for conduct during his recent rehab assignment. According to ESPNNewYork.com's Andrew Marchand, a hand-delivered letter written by Yankees GM Brian Cashman informed A-Rod that the club plans to punish him for seeking a second opinion on his quadriceps injury and also for failing to appear at Yankee Stadium last month after meeting with MLB officials to discuss the Biogenesis investigation. In an article by Bryan Hoch and Josh Vitale of MLB.com, however, A-Rod denied receiving the letter. "Maybe they sent it to my lawyers," Rodriguez said. "But I'm not really going to talk about that."

• Neither Ian Desmond nor Jordan Zimmermann appear close to contract extensions with the Nationals, Bill Ladson of MLB.com reports. Zimmermann, 27, said his camp and the Nationals broached the subject in the offseason but didn't come close to an agreement. "I'm not going to give a huge team discount," Zimmermann warned. "Just something fair is all I ask."Meanwhile, Desmond recognizes that he has two years of arbitration remaining and doesn't appear to be in a hurry to put together a deal, according to Ladson.
• Everth Cabrera's recent suspension has reinforced the fact that the Padres' farm system is thin on shortstop talent, Jeff Sanders of the San Diego Union-Tribune says. “You’d like to have a shortstop at every level that you feel is a prospect – has a chance to be an everyday guy,” assistant GM Chad MacDonald said. However, as Sanders notes, the club's best prospects at the position remain in the lower minors. For now, former first-round pick Logan Forsythe figures to get an extended look at short for the Friars.
• Astros top prospect George Springer may finish the season at Triple-A, Brian McTaggart and Chris Abshire of MLB.com say. Springer, 23, is hitting .303/.410/.597 with 38 stolen bases across stops at Double-A and Triple-A this season. However, Astros manager Bo Porter didn't give any indication of when Springer might be called up to the major league club when discussing the outfielder today.
• Will Middlebrooks was called up to man third base for the Red Sox because he has more experience at the hot corner than Xander Bogaerts, Scott McLaughlin of WEEI.com reports. Many speculated that Bogaerts, who's hit .300/.392/.487 in 481 minor league plate appearances this season, would get the call, but manager John Farrell says the team prefers that he continue to take reps at third in the minors. The Sox want Bogaerts to be ready in case Middlebrooks struggles or hits the disabled list, according to McLaughlin.
