Paxton (forearm) will throw a bullpen session Wednesday or Thursday, a precursor to a rehab assignment, the Seattle Times reports.

Paxton's swift progress has been dubbed "great news" by Mariners manager Scott Servais. If all goes well, he'll likely go on a rehab assignment next weekend, with a chance of returning at some point during Seattle's next road trip, which begins May 23. Considering how scary forearm tightness can be for pitchers -- especially those with electric arms like Paxton -- this swift turnaround should elicit sighs of relief from the lefty's fantasy owners.
