Heimbecker was a player our staff was eager to see as he went up against some older competition in front of college coaches and the 5-foot-11, 178-pound middle infielder was up to the challenge. The Ontario Nationals product put together one of the top overall performances on workout day and carried that into gameplay where he picked up several hits including a double into the pull-side gap. Left-handed bat with plenty of growth and maturity to come.
