Lucas Duda is reconstructing his swing, a tweak that appears to be taking a toll on his strikeout totals. In two games and seven at-bats, Duda is 0-for-7 with six strikeouts.

"He’s not getting his feet down in the batter’s box," manager Terry Collins said after Sunday afternoon’s 7-all tie with the Houston Astros. "He’s trying to change his stride a little bit to keep it so it’s not so much movement. And he’s just not getting himself in hitting position right now."

Collins has insisted that Duda will be the team’s starting left fielder on opening day.

"Today he had a terrible day," Collins said. "But it’s going to come with trying to make the adjustments he’s trying to make."

Feliciano’s condition

Pedro Feliciano joked that he has a condition so obscure that reporters might want to label it "Feliciano’s Condition."

Feliciano said he’s not experiencing any negative symptoms, but routine tests revealed the reliever has an issue with his heart. General manager Sandy Alderson said Feliciano will wear a monitor over the next two weeks to ascertain the severity of the issue.

"Until that time," Alderson said, "we won’t really have a diagnosis."

Alderson said Feliciano will not be involved in any baseball activity until the team learns the results of those tests.

"I hope when I come back I pitch good and surprise everybody and make the team," Feliciano said.
