Seattle Mariners pitcher James Paxton (back) is scheduled to throw a bullpen session on Saturday. If all goes well, he could return to the team's rotation on Tuesday. He has been out since Jul 12 with lower back stiffness. He has pitched to a 8-4 record with a 3.70 ERA and a 155/33 K/BB ratio. Assuming he returns on Tuesday he'll be in play in both season-long and daily leagues.
