|Alex White never realized his potential in a Rockies uniform.|
Lopez is a 29-year-old who owns a career ERA of 3.14 since 2009. He went 6-3 with a 2.17 ERA with 10 saves for the league-worst Astros in 2012.
White leaves Colorado as a tremendous disappointment after being seen as a potential front-end starter when he was included in the Jimenez trade that also brought back Drew Pomeranz. The problem for the right-hander was as simple as not throwing enough strikes. He got behind in counts far too often, then gave up the long ball after being forced into fastball counts.
