Somewhat lost in the announcement of the hire of Mark Loretta as Cubs bench coach Wednesday was the simultaneous announcement that former pitcher Bob Tewksbury was named as a mental skills coordinator on the Cubs staff.
Tewksbury was an extreme ground-ball pitcher during his big-league career, which included a 6.4 bWAR season in 1992 with the Cardinals in which he finished third in Cy Young voting.
In that season Tewksbury threw 233 innings and issued 20 walks.
Twenty. Tyler Chatwood issued more walks than that (22) in April 2018, when he threw a total of 28u2154 innings.
