Trent Harris

The 27-year-old Harris has a 2.14 ERA and a 27/7 K/BB in 21 innings since getting his first major league callup on Aug. 7. He’ll be off Tuesday after working the last two days, so Dylan Smith might get a save chance then.

The Giants have seven saves since the trade deadline, and Harris is the fifth different reliever to earn one. Dylan Smith is the only one with multiple saves during this span, but Tony Vitello has been using a closer by committee all season long. Harris’ save against St. Louis was the first of his big-league career.

Harris will provide the Giants with a fresh arm that’s capable of working multiple innings for Friday’s bullpen game against the Tigers. It’s the first trip to the big leagues for the 27-year-old right-hander. He posted a 3.12 ERA, 1.36 WHIP and a 52/18 K/BB ratio over 40 1/3 innings in 29 appearances at Triple-A Sacramento.
