Alfaro didn't appear in the big leagues last year and has officially achieved journeyman status after spending time with four different clubs during the previous three seasons. The 31-year-old is a one-dimensional slugging backstop at this stage of his career and never quite lived up to the astronomical hype as one of the most highly-regarded catching prospects of the last decade. He'll bolster Milwaukee's catching depth heading into spring training behind William Contreras, Eric Haase and top prospect Jeferson Quero.
