Giants Designate D.J. Snelten, Release Hector Sanchez

The Giants have designated left-hander D.J. Snelten for assignment, Kerry Crowley of the Bay Area News Group reports. Additionally, the club has released catcher Hector Sanchez, per Alex Pavlovic of NBC Sports Bay Area. Sanchez recently suffered his eighth concussion, Pavlovic notes.

The 25-year-old Snelten’s exiting the Giants’ 40-man roster to make room for the addition of righty Dereck Rodriguez. Snelten, a 6-foot-7, 245-pounder, joined the Giants in the ninth round of the 2013 draft and worked his way to the majors this year. He struggled across 4 1/3 innings, though, allowing five earned runs on nine hits and three walks (with four strikeouts). Snelten has been far more effective at Triple-A since last season, having combined for a 2.84 ERA with 7.5 K/9 and 3.5 BB/9 over 69 2/3 frames.

Sanchez, 28, has spent the majority of his professional career in the San Francisco organization. He made his pro debut back in 2007 and ascended to the majors in 2011, later seeing extensive action with the Giants from 2012-14. He left the Giants after 2015 and spent the ’16 campaign with the White Sox and Padres, only to return to San Francisco the next season.

Sanchez stayed with the Giants on a minor league deal over the winter, but he hasn’t seen any major league action this year. In all, he has amassed 834 plate appearances in the majors, including 637 with the Giants, and hit .238/.273/.367.
