PHOENIX -- One day later, D-backs manager Kirk Gibson had a little better handle on what went wrong for starter Daniel Hudson.
Hudson allowed seven runs on 10 hits in lasting just four innings against the Mariners on Tuesday night.
The outing was disappointing, as it came off a fine performance against the Rangers when it seemed he had turned the corner from his struggles.
"They're a very aggressive team," Gibson said of the Mariners. "And if you notice, early he'd get behind in the count and he'd throw his changeup or his secondary stuff, and he wasn't getting strikes, they weren't good enough to get swings. In the end, he was elevating a little bit."
Not being able to get his secondary stuff over especially early was a problem.
"They like to whack the fastball early," Gibson said. "So you have to pitch around that, and he was just unable to execute."
