As expected, most of our Rookies are being seasoned at the Spring Training facilities of their parent club in Arizona and Florida. I would speculate they will all be starting out in "A" or possibly "Advanced A" ball next spring.
#14 Wade Meckler: Giants Rookie League team - Arizona Complex League (.400 BA)
#61 Jacob Melton: Astros Blue Rookie Team - Florida Complex League ( 0-13 start)
#27 Justin Boyd: Daytona Beach - Florida State League (Class A). (.429 BA)
#52 Gavin Logan: Diamondbacks Rookie League Team - Arizona Complex League (.333 BA)
#63 Jake Pfennigs: Athletics Rookie League Team - Arizona Complex League (hasn't pitched)
#55 Will Frisch: Cubs Rookie League Team - Arizona Complex League (hasn't pitched)
Cooper Hjerpe and D;J. Carpenter are at the St. Louis Cardinals Spring Training facility in Florida (Instructional camp).
I would guess, our four pitchers may be shut down competitively for the year - they have just completed a 56 game season. Some may eventually see an outing or two of 1-2 innings. I attached their numbers in case you catch any video or stream.
