3:22pm: The Phillies have "put the brakes" on their attempt to acquire Lopez, Salisbury reports. Lopez had traveled to Philadelphia for a physical yesterday. It's not clear if there's a physical issue that's limiting the Phillies' interest.
1:20pm: The trade is now unlikely to happen, sources told Todd Zolecki of MLB.com.
THURSDAY, 9:40am: The status of the trade remains unclear, Ken Rosenthal of FOX Sports reports (Twitter links). One of Rosenthal's sources says the deal isn't done and multiple teams are in the mix for Lopez. Another person said it would be a two for one trade, potentially with right-hander Tyler Cloyd going to Houston. The clubs have discussed the Phillies' young catchers, according to Rosenthal.
WEDNESDAY: The Phillies and Astros have agreed to a trade that will send Wilton Lopez to Philadelphia for minor leaguers, Jon Heyman of CBSSports.com reports (on Twitter). The teams are finalizing the details of the deal.
Lopez, arbitration eligible for the first time this offseason, projects to earn $1.4MM in 2013. The 29-year-old posted a 2.17 ERA with 7.3 K/9, 1.1 BB/9 and a 55% ground ball rate in 66 1/3 innings with the Astros in 2012. In three-plus MLB seasons, he has a 3.14 ERA with 6.8 K/9, 1.6 BB/9 and a 55.9% ground ball rate. He's under team control through 2015.
The Phillies had been looking to acquire a reliever who can provide steady late-inning production. Lopez has pitched at least 65 innings in each of the past three seasons without posting an ERA above 3.00, so he'll be a welcome addition to the Philadelphia 'pen.
Jim Salisbury of CSNPhilly.com first reported the teams were seriously discussing a trade involving Lopez.
