Editor's note: For the past few weeks, NBC Sports California has been analyzing a different A's player each day to project their numbers for next season.
For most of the 2018 season, Lou Trivino was untouchable.
The A's rookie reliever carried an 8-1 record and 1.25 ERA into August, along with four saves and 14 holds. Trivino struggled down the stretch, possibly due to fatigue, but still finished the year 8-3 with a 2.92 ERA and 1.14 WHIP, striking out 82 batters in 74 innings.
Trivino, 27, will look to build on that effort this coming season, as he figures to be the primary setup man for All-Star closer Blake Treinen.
