Major League Baseball announced on Thursday that Tampa Bay's waiver claim of left-handed pitcher Bobby Livingston two days ago was now void, and subsequently nullified the Rays' deal with the Phillies.
"We felt that it circumvented the rules of claiming players on waivers," MLB spokesman Patrick Courtney said. "It wasn't following the order of teams on the list."
The Phils had originally acquired the 24-year-old southpaw from the Rays for cash considerations. Following the nullification, the Reds claimed the left-hander from Mariners, because Philadelphia was behind Cincinnati and other clubs for waiver claims.
"Our interpretation of the rule was the same as the one for the Rule 5 Draft," Phillies assistant general manager Mike Arbuckle said. "We were unaware of this rule. When the Commissioner's office ruled that we had to send him to Cincinnati, we were surprised."
Livingston spent most of last season with the Mariners' Triple-A club in Tacoma and went 8-11 with a 4.59 ERA in 23 appearances, including 22 starts. He made his Major League debut in 2006 when he appeared in three games with Seattle as a reliever.
