There are three other spots open, and RHP Yusmeiro Petit will almost certainly receive one of those spots as a long reliever. Petit earned his spot because he had a 3.59 ERA in seven starts at the end of last season, and he came within one strike of a perfect game in one of those starts.
To narrow it down even more, it seems like Hembree, Huff, and Kontos will be fighting for those last two spots. Bochy normally likes to have three left-handed relievers, so it would make sense if Huff earned one of those spots too.
When Hembree was called up from the Fresno Grizzlies to the Giants in September, he appeared in nine games and finished with a 0.00 ERA with 12 strikeouts. Hembree is a hard-thrower with a lot of upside, so it’d make sense if he made the 25-man roster.
However, if Kontos has an impressive Spring Training and proves that he can consistently throw his slider again, there’s a strong possibility that Bochy will pick Kontos over Hembree for that last spot.
If a final roster spot comes down to two players, Bochy normally gives the edge to the player with more major-league experience or more experience with the club, and, in that case, it’d be Kontos. The Giants would always be able to bring up Hembree later on in the season after gaining more experience in Fresno.
