MILWAUKEE, WI (WHBL) - Milwaukee Brewers’ general manager Doug Melvin says the team’s late-season comeback convinced him that wholesale changes will not be necessary for 2013. At the Brewers’ season-ending news conference yesterday, Melvin said he would only need to fine-tune the starting positions – and he’d like to add another starting pitcher over the winter. The G-M expects Corey Hart to stay at first base and Norichika Aoki to remain in right field. That means Mat Gamel might have to play a utility role when he returns from a torn A-C-L knee injury. Also, Carlos Gomez is expected to keep getting more playing time in center after he had his best season at the plate with a .260 batting average, 37 stolen bases, and 19 homers. Logan Schafer could move into the backup spot in center if the struggling Nyjer Morgan is cut. Melvin says his biggest task will be to have an experienced starter join Yovani Gallardo. Shaun Marcum is expected to shop around as a free agent. And Melvin was not sure about Milwaukee’s chances of keeping him, especially with his elbow problems and the seven-million-dollar-plus salary he made this year. There’s been talk that Angels’ free agent Zack Greinke might be interested in returning after he was traded in July. Greinke turned down a five-year, 100-million-dollar offer to stay with Milwaukee. However, Melvin said his gut feeling is that the Brewers won't go after any high-priced free agents - and Greinke is expected to be the top pitcher on the free agent market and will command top-tier money. Changes are also expected in the bullpen, where Kameron Loe, Manny Parra, and Jose Veras are all up for salary arbitration.
