EDGE Analysis

Tolleson has allowed seven runs on three home runs in his last two outings. He has a 9.20 ERA on the season and opponents are hitting .343 off him. It was about this time last season that manager Jeff Banister pulled Neftali Feliz out of the closer's role and went with Tolleson. "I definitely have a level of concern," Banister said. "That's one I'm not ready tonight to make a decision on. Obviously his fourth blown save, it's a challenge. We've got to be able to make pitches and end the game ... close the game out after we fought back and took the lead."
