Major League Baseball has found that Anthony Rizzo's eighth-inning takeout of Pittsburgh Pirates catcher Elias Diaz in Monday's game was illegal.

Diaz subsequently threw the ball into right field while attempting a double play, allowing two runs to score in Chicago's 7-0 win. The play was reviewed, and the call on the field was upheld.

Clint Hurdle disagreed with the call at the time and was ejected.

Maddon and MLB Chief Baseball Officer Joe Torre spoke on Tuesday.

"It was a good baseball play," Maddon said. "It was interpreted the next day as being wrong, which I totally find incongruent."

The league determined Rizzo altered his path to slide into Diaz, who went down as the ball sailed into right field. The umpires found Rizzo did not alter his path enough for the Cubs to be penalized.

"The umpires got it right," Maddon said. "It's almost like a doctor reading an MRI. You might get two different opinions with the same set of information. ... I will not back down from that. I believe I'm right."
