Jon Niese passed a battery of heart-related tests Tuesday at Henry Ford Hospital, assistant GM John Ricco said. Niese experienced a rapid heartbeat Saturday at Texas. He is wearing a heart monitor for a day to ensure no abnormalities before being cleared to pitch Friday against the Yankees. Ricco said trainers have labeled what Niese has experienced on occasion as tachycardia, which by definition is a rapid heartbeat.
• David Wright took groundballs and played catch in Port St. Lucie on Tuesday. Terry Collins expected Wright would begin hitting off a tee Wednesday.
• Johan Santana, who halted throwing off a mound at the beginning of the month after experiencing discomfort in his surgically repaired left shoulder, was scheduled to return to a mound Tuesday. However, inclement weather in Port St. Lucie delayed that occurring. Pitching coach Dan Warthen said Santana “feels good.”
• Ike Davis, who has cartilage damage in his left ankle that may require season-ending surgery, is at home in Arizona doing what Ricco labeled “light rehab.”
