With Martin Perez injured, many have speculated that the Rangers could make a play for free-agent pitcher Kyle Lohse. That doesn't appear to be the case, according to MLB.com's T.R. Sullivan. A Rangers source told Sullivan, “We are not going to sign Kyle Lohse. I can't be clearer than that.” The team has signed pitcher Derek Lowe to a minor-league deal, CBSSports.com's Jon Heyman has confirmed, so it appears he could be Perez's replacement. The team is probably right in not overreacting to losing Perez. While he has been a top prospect in the organization for multiple seasons, his numbers haven't matched his hype in recent years. Given that the Rangers were likely not expecting a huge season from Perez immediately, they are probably fine with getting by with a low-upside option at this point. With Colby Lewis expected to be ready by mid-season, the club only needs Lowe, or whoever its fifth starter may be, to last a couple of months.
