Jake Junis is not particularly sexy as a middle relief option. He relies heavily on his slider which grades out well and his strikeout rate spiked in 2023 to 10 K/9, but his fastball is middling at best and his only okay 3.87 ERA was the best mark he has posted as a big leaguer.
It would be completely fine if Junis came back, but the Giants shouldn't break the bank to bring him back. One interesting landing spot for Junis would be the Phillies who have some high octane arms in their bullpen and Junis would be a nice change of pace guy to have in the sixth or seventh inning.
Prediction: Phillies - Two years, $6.5 million
Of the Giants' relievers that are set to hit free agency, Brebbia is arguably the most exciting one. He struck out 11 batters per nine innings pitched this season and has been one of San Francisco's most consistent relievers for the last couple of years outside of a lat injury that sidelined him for a chunk of the 2023 season.
Assuming he is completely healthy again, the Giants bringing him back makes a ton of sense. Brebbia is 33 years old, so giving him anything but a one year deal is probably unwise. However, giving him a slight pay bump on a one year deal seems like a deal that could be reasonable for both sides.
Prediction: Re-signs with the Giants - One year, $3.2 million
