"If there is a situation where it's predominantly right-handed, then definitely it would be Drew," Riggleman said. "If it's predominantly left-handed, I would want to have [Burnett] there."
Riggleman did mention that he would not hesitate to use Burnett as early as the seventh inning, depending on the matchups. The lefty will likely have a night off Thursday after making four consecutive appearances.
On Wednesday, Burnett suffered a blown save and watched his ERA rise from 2.61 to 5.73. Burnett is 3-for-5 in save opportunities this season, while Storen holds a 0.69 ERA and has also collected three saves.
"I just want to get outs in the ninth," Riggleman said. "I'm not going to get too caught up on who gets the save. I just want us to get the save and, more importantly, the [win]."
