This article is the fourth in a series about areas in which the Jays need to improve to contend in 2018. The first article was about beating the bad teams, the second was about winning in April, and the third concerned Roberto Osuna. The focus is not on large targets – like staying healthy, or scoring more runs than the other guys – but rather on smaller areas where the Jays have underperformed in recent years and where improvement could translate into those critical few additional wins.
