Volodymyr Zelensky literally left his mark on America's pastime ... the world leader autographed a baseball that's up for auction, and the sale will help relief efforts in Ukraine.
The Ukrainian President signed his last name on the baseball in two different languages ... Ukrainian cursive and English print ... with his signature right below a Major League Baseball logo.
Zelensky left his John Hancock on the ball back in September 2019, during a visit to New York. The ball comes with a letter signed by Volodymyr Yelchenko, Ukraine's Ambassador to the United Nations at the time.
