Spencer Arrighetti, Blake Snell, and Zebby Matthews are among the notable pitchers facing injury challenges this season, causing concern for fantasy baseball managers. Arrighetti, a promising talent with a 3.04 ERA last season, is recovering from a broken thumb and is expected to return around the All-Star break in July. Snell, who has a history of injuries, is dealing with shoulder inflammation and might not be back until mid-July, making him a candidate for stashing on fantasy rosters. Finally, Matthews, who started strong this season, is sidelined with a moderate shoulder strain and has an uncertain return timeline, making him less favorable for keeper leagues.
