Slater has joined the Giants on their trip to Philadelphia and will have his contract purchased from Triple-A Fresno on Thursday, Andrew Baggarly of The San Jose Mercury News reports.

Slater is probably going to get work in left field with the big club, according to Henry Schulman of the San Francisco Chronicle. The former infielder has spent all of his 2017 farm games in the outfield or at designated hitter, and he's raking at Fresno (.322/.381/.460 with four home runs and 26 RBI in 196 plate appearances). The 24-year-old ranks a tepid 16th on RotoWire's Giants prospect rankings but could wind up as a useful depth piece in NL-only fantasy games -- if only for a brief stretch -- should he lock down at least a part-time role. Of course, the impending return of Hunter Pence (hamstring) could throw a wrench into that plan.
