The San Francisco Giants are shifting around their pitching staff, including calling up a rookie to make his MLB debut.

On Friday morning, the Giants announced their roster moves for the day. Right-handed pitcher Carson Seymour has been re-called from Triple-A and struggling reliever Sean Hjelle is being optioned down there as the corresponding move.

Seymour was acquired a few years ago during the J.D. Davis and Darin Ruf trade, sort of just being thrown in. Now, he has progressed into an intriguing starter and could become the most impactful player involved in the deal.

The 26-year-old has a power sinker and two-seam fastball combination with solid slider to boot. While he has been starting in the minors, he could make sense as a bullpen arm as well.

In 15 starts at the Triple-A level this year, he has posted a 3.89 ERA with a 1.351 WHIP and 10.1 K/9. He strikes a lot of batters out, but also has an issue with walks. He has a 4.55 FIP, meaning that there is some room to grow still.

Hjelle getting optioned seems like it could be the best path forward for all involved right now, while the off-the-field issues get settled.

Last Saturday, San Francisco confirmed that MLB was investigating Hjelle after his wife alleged abuse in a social media video that went viral.
