The Eduardo Rodriguez Acquisition

The Diamondbacks signed free agent Eduardo Rodriguez. Let’s look at whether his performance was better than Lucas Giolito, who is another starting pitcher that the Diamondbacks might have signed.

The following table looks at several performance measures. Eduardo Rodriguez’s metrics look better except for three of my preferred metrics (strikeouts per batter faced, whiffs per pitch, and balls-in-play per strike). Even with a Giolito bounce back, it’s likely that Eduardo Rodriguez will outperform in many metrics next season.

Although it’s possible that Rodriguez will get as many whiffs as Giolito, that’s not bad because Rodriguez is a different type of pitcher.
