Baseball Prospectus has this to say today about Luis Guillorme (you might remember him as the Bat Catcher): Luis Guillorme, SS, New York Mets (Double-A Binghamton) When watching Guillorme play, it does not take long at all to see that he is a special defensive player. He possesses strong, fast hands (Exhibit A) with a plus arm, quick release, and excellent range. His defense alone should allow him to make a big-league roster. The difference between a bench and regular role will be his offensive development, and Guillorme is enjoying a breakout season at the plate thus far. Through his first 101 plate appearances, he is slashing .326/.400/.382. He has never hit for power, and at 5-foot-9 and 190 pounds, don’t expect that to suddenly change. Nor will he impact the game on the basepaths. However, he has displayed a potential average hit tool in Double-A with decent plate discipline. Yes, an unsustainable BABIP of .397 suggests some regression going forward. Nonetheless, due to his strong hands, impressive hand-eye coordination, and good bat control, he consistently makes contact to all parts of the field. Amed Rosario is certainly a much more exciting prospect. He has a more athletic frame, runs well, and is noticeably better at the driving the ball. While Rosario will likely become the Mets' starting shortstop in the near future, Guillorme's stock is on the rise and should reach the majors at some point in 2018. —Erich Rothmann
