Manny Ramirez left Des Moines as surprisingly as he came.

The controversial slugger's tenure as a player-coach with the Iowa Cubs has come to an end, manager Marty Pevey said before Friday's game at Principal Park.

Pevey said that Ramirez, who was placed on the disabled list Aug. 23 with a knee injury, went to Arizona to get an MRI. Pevey added that Ramirez's trip out of town has ended his season with Iowa.

The Cubs began Friday with just four regular-season games remaining.

"He's been awesome," Pevey said. "Done a great job. Been great in the clubhouse and he's been such a good teammate."

Ramirez, 42, was a dynamic figure on and off the field as one of baseball's most successful right-handed hitters of all time.

He tallied a .312 batting average and connected on 555 home runs during parts of 19 big-league seasons. But those accomplishments were overshadowed by Ramirez's wacky behavior and run-ins with Major League Baseball's rules police.

Ramirez was suspended twice for violating MLB's drug policy.
