Mets starting pitcher Zack Wheeler will take the mound for the third time Sunday, and he thinks he will have his pitch-tipping issues solved. Wheeler worked with pitching coach Dan Warthen Thursday and Friday, and told MLB.com he thinks he has a grasp on the issue.

"I don't think it's anything too difficult," Wheeler said. "Just a little small tweak here and there, and we'll be good to go."

Wheeler is working on correcting his arm slot, which has been inconsistent depending on whether he is throwing a fastball or breaking pitch. The much-hyped prospect has been underwhelming in his first two starts, walking as many batters as he has struck out (eight) in 11 1/3 innings of work.
