Elbow or shoulder surgery probably could, but hopefully that doesn't become an issue.
In 89 2/3 innings this season between Class A-Advanced Charlotte and Double-A Montgomery, Snell owns a 30.3% strikeout rate and 11.4% walk rate. Obviously that one has to come down, but it clearly hasn't prevented him from being very successful this season.
Triple-A Durham Bulls (49-45)
Dylan Floro dominated in Durham's 3-0 win over Pawtucket. After a stretch of five terrible starts, he now has two quality starts in a row. He struck out six in six scoreless innings, walked none and only scattered two hits.
