It’s not too difficult to determine the source of Holland’s success, at least statistically. His walks per nine innings have dwindled significantly, while his strikeouts per nine innings have increased sharply.
The left-hander is winding down an impressive debut season. His 3.67 ERA is the lowest by a Padres rookie since Cory Luebke posted a 3.29 mark in 2011. Still, Lucchesi has yet to complete seven innings in a game this season.
