Joe Vavra is currently the third base coach for the Minnesota Twins. He has two sons who have recently joined the Twins organization after being drafted out of college. Tanner was the Twins’ 30th round pick in the 2013 MLB Draft out of Valparaiso University and is currently a second baseman for Cedar Rapids in the Midwest League. Trey, a 33rd round pick of the Twins out of Florida Southern College in the 2014 MLB Draft, is a first baseman with Elizabethton in the Appalachian Rookie League.
Joe insists he did not try to influence the Twins in selecting his sons, that they earned their shots on their own merits.
