SCOTTSDALE, Ariz. (AP) – An overexcited Matt Garza struggled in his Brewers debut Sunday, allowing four runs in the first inning of Milwaukee’s 6-5 win over the Colorado Rockies. The right-hander, who said he had trouble sleeping Saturday night, allowed four hits and walked two. His 28-pitch outing included only fastballs and changeups. Carlos Gonzalez had an RBI single and Michael McKenry a two-run double against Garza. He signed a four-year, $50 million free-agent deal in the offseason after playing for the Cubs and Rangers last year. Colorado starter Jorge De La Rosa also had command trouble. De La Rosa gave up a leadoff home run to Rickie Weeks and was lifted with two outs in the second after allowing four runs. He gave up four hits with two walks, a wild pitch and a throwing error.
