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

EDGE Analysis

Paxton's swift progress has been dubbed "great news" by Mariners manager Scott Servais. If all goes well, Paxton will likely go on a rehab assignment next weekend, with a chance at 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 is looking like it will be a swift turnaround for the lefty.
