In desperate need of any sort of excitement surrounding the team after the loss of ace pitcher Madison Bumgarner for 6-8 weeks after a dirt bike accident, plus the fact the team is not winning; the San Francisco Giants called up top shortstop prospect Christian Arroyo on Monday. Whether Arroyo is ready or not and if this is a panic move by the Giants is up for debate but there is no denying the fact the former 2013 first-round pick is going to be a very good player. In terms of fantasy baseball though, Arroyo may not be a big help just yet. Consider that at Double-A a year ago, Arroyo hit just .274 with all of 3 home runs and 1 steal in 517 at-bats. That is your epitome of an empty average but at just 21, Arroyo has not filled in yet physically. While I think he will eventually add some power, Arroyo is really more defense than offense at this point. So in NL-only leagues you can be more aggressive on the kid but in mixers Arroyo is just a speculative add.
