Mariners manager Lloyd McClendon said Sunday he's concerned about the lack of African-American players and managers in baseball.

In the last few weeks, two African-American managers left the game in Houston's Bo Porter, who was fired, and on Friday, Texas' Ron Washington resigned, leaving McClendon as the only black man as a manager.

"It's concerning," McClendon said. "Not just from a managerial standpoint but from a player standpoint, in what's happening with baseball in the inner cities. I think from all the conversations I've had, I know Major League Baseball is committed to bringing [it] back to the inner cities. I think from a philosophical standpoint we're missing some ideas that need to be in there."
