Sportsbook Wire cast doubt on Zach Eflin's upside in his upcoming start against Arizona. Eflin owns a modest 3.75 ERA and ranks low in strikeout rate (5.2 K/9 - 80th among qualifiers). He faces a D-backs offense that's been explosive, ranking fifth in MLB with 58 runs, hitting .261 with a .450 slugging percentage (sixth-ranked). Despite Eflin's solid WHIP (.917, 19th-ranked) and consecutive six-inning quality outings, the tough matchup against a lineup that's scored prolifically and hit for power tempers expectations. Eflin could be a fade candidate in DFS and betting given the offensive strength he's up against.
