Week 5 in fantasy baseball calls for strategic waiver wire moves, especially for starting pitchers. Among the top picks is Andrew Heaney of the Pittsburgh Pirates, who, despite a fastball under 90 MPH, has been effective with a 5.1% walk rate and an impressive K% of 26.3% in his last four starts. Mitchell Parker of the Washington Nationals also stands out, boasting a 1.39 ERA, but his low strikeout rate may limit his overall value. Landen Roupp from the San Francisco Giants shows promise with a significant K% increase, though inconsistency in his ERA raises questions. Jose Quintana of the Milwaukee Brewers remains a reliable option for controlling ratios and winning potential, albeit with limited strikeout upside. Deeper leagues may find value in Reese Olson of the Detroit Tigers, who has improved rapidly, and Matthew Liberatore from the St. Louis Cardinals, boasting four quality starts. Tobias Myers and Shane Smith, both rostered under 30%, are also worth consideration for streaming options.
