Chicago Cubs relief pitcher Daniel Palenica (elbow) was activated off the 60-day Injured List ahead of Friday's game against the Seattle Mariners, Taylor McGregor reports. Palenica is officially back in the mix after being sidelined since mid-June due to an elbow issue. When healthy, Palencia has posted a 2.70 ERA, 1.38 WHIP, and a 19/6 K/BB ratio across 16.2 innings of work in 19 appearances. Jacob Webb was pitching well as the closer while Palencia was out, but he'll move out of that role now. Fantasy managers looking for a source of saves should snag Palencia off the waiver wire before it's too late. In a corresponding move, right-hander Javier Assad was optioned to Triple-A Iowa on Friday

According to Alex Pavlovic, San Francisco Giants infielder Marcelo Mayer (forearm, foot) has paused his rehab assignment due to a bone bruise in his right foot. The plan is for Mayer to rest through the weekend before being re-evaluated next week. He originally landed on the Injured List in late June with a left forearm stress reaction. Now, he'll need to hold off on his rehab assignment for a few days while he recovers from this foot injury. Mayer was nearing a return to the Giants, so hopefully this won't set him back too far. Fantasy managers should check back for an update on his status after he is re-evaluated.

Seattle Mariners starting pitcher Bryan Woo won't make his scheduled start against the Chicago Cubs this weekend. According to Adam Jude, Woo will be pushed back from his scheduled outing on Sunday. Instead, Kade Anderson will get the ball on Saturday, while Bryce Miller gets the starting nod for Sunday's series finale. Woo was removed early during his most recent start against the Houston Astros due to shoulder soreness. It sounds like Woo is still dealing with some soreness, but is expected to be worked into the rotation at some point next week. At the moment, there are no plans to have Woo placed on the Injured List, but it shouldn't be completely ruled out. Fantasy managers should check back for another update on Woo next week.

St. Louis Cardinals starting pitcher Hunter Dobbins (forearm) was forced to make an early exit from Saturday's start against the Philadelphia Phillies. According to Derrick Goold, Dobbins left this game early due to right forearm tightness. Dobbins was pulled after throwing one pitch in the fifth inning. His day finishes with three earned runs on five hits while striking out three batters across four innings of work. The Cardinals haven't said whether or not Dobbins will require a trip to the Injured List. Brycen Mautz could get a shot in the rotation if Dobbins does miss time. Fantasy managers will need to check back over the weekend for another update on his status.
