Cardinals pitcher Lance Lynn believes he may have been tipping his pitches earlier in the season, according to the St. Louis Post-Dispatch.

Lynn and team coaches determined he may have been tipping his pitches during his June 6 start based on how hitters were reacting to his breaking balls. Lynn worked to eliminate any differences in his windup, and focused on positioning his hand the same way no matter what pitch he was throwing. 

Lynn has been excellent over his last three starts, allowing two earned runs over 22 innings.
