Slater is dealing with a strained flexor and a mildly sprained UCL, Andrew Baggarly of The Athletic reports. Slater is not in the lineup for Sunday's season finale with the Dodgers, and this diagnosis makes it seem like he won't be available off the bench at all. He'll now turn his attention to rehabbing for the 2019 season after producing a .251/.333/.307 slash line in 225 plate appearances for San Francisco. If he can get healthy in time for spring training, Slater will likely vie for a starting outfield job with the Giants.
Slater exited Friday's game with an elbow strain and will undergo tests to determine the severity of the injury, Alex Pavlovic of NBC Sports Bay Area reports. After the conclusion of Friday's series opener against the Dodgers, Slater stated that he suffered the injury while attempting to throw out a baserunner at home plate, which left him unable to hit during his next at-bat. With just two games remaining in the 2018 season for San Francisco, it would come as a slight surprise to see him back on the field later this weekend.
Slater struck out in a pinch-hit appearance Monday against the Padres. Slater was expected to take over at first base after Brandon Belt (knee) was shut down for the season, but he has been situated on the bench for five of the club's last six contests. Instead, Aramis Garcia has been seeing the majority of starts at first, and the Giants' persistence on starting veteran outfielders Gregor Blanco and Hunter Pence in a lost season has left Slater without regular playing time.
Slater is not in the lineup Saturday against the Cardinals, Andrew Baggarly of The Athletic reports. Slater sits for the third time in the last four games. Hunter Pence will start in right field, with Joe Panik starting at first base.
Slater is out of the lineup versus the Padres on Wednesday, Henry Schulman of the San Francisco Chronicle reports. Slater will take up a spot on the bench for a second straight day as Hunter Pence gets a start in right field for the series finale.
