Tolleson, limited by a back injury to start the spring, has been able to throw as scheduled over the past two weeks.
EDGE Analysis
Tolleson is expected to make at least one more appearance over the weekend as a final preparation for the season opener Monday. He'll begin the year as Texas' closer, but manager Jeff Bannister was quick to remove Tolleson from that role in the postseason in favor of Sam Dyson so the leash figures to be a bit shorter here than with more established closers.
