The Brewers claimed pitcher Marco Estrada off waivers from the Nationals, reports Tom Haudricourt of the Milwaukee Journal-Sentinel. In a corresponding move, Milwaukee designated Tim Dillard for assignment.
Estrada, 26, posted a 3.63 ERA, 6.5 K/9, and 2.2 BB/9 in 136.3 Triple A innings last year. In their new Handbook, Baseball America had him ranked as the Nationals' #18 prospect. They praised his change-up, and suggested he could become a back-end starter despite being undersized. The Nats designated him for assignment recently to make room for Tyler Walker.
Dillard, 26, posted a 4.51 ERA, 3.9 K/9, and 3.2 BB/9 in 147.6 Triple A innings last year. He'd spent the previous year as a reliever. He garnered a mention as the Brewers' #30 prospect in the '09 Handbook, when he profiled as a "resilient middle reliever." It seems clear that the Brewers upgraded going from Dillard to Estrada, and Dillard may be retained anyway if he's not claimed off waivers.
