Here's MLB Pipeline's roundup of the top prospect performances in the Minor Leagues on Tuesday.
Once viewed as the least-known prospect acquired from the Mariners in the offseason Dee Gordon trade, Robert Dugger has shed that distinction in his first season with Miami.
Dugger, the Marlins' No. 22 prospect, set a career high with 10 strikeouts over seven scoreless innings to lead Double-A Jacksonville past Birmingham, 3-1, and record his fourth win in five starts. He struck out seven consecutive batters at one point in the outing and ultimately allowed three hits and two walks while throwing 63 of his season-high 107 pitches for strikes.

The 23-year-old right-hander struck out the side during a perfect first inning and then fanned the final two batters in the following frame. Dugger struck out the side in the third inning and posted back-to-back strikeouts to open the fourth to complete his stretch of seven straight strikeouts. Over his final 3 1/3 frames, Dugger did not record a strikeout.
