The Dodgers promoted Nastrini from High-A Great Lakes to Double-A Tulsa on Monday, Kyle Glaser of Baseball America reports.
With right-handed starters Bobby Miller and Gavin Stone getting bumped up to Triple-A Oklahoma City, Nastrini will step up to help fill the void in the Double-A rotation. Nastrini's promotion comes after he delivered a 3.86 ERA, 1.16 WHIP and 127:39 K:BB in 86.1 innings with the High-A club.
