Diaz (2-2) fired a scoreless ninth inning in Wednesday's 6-5 win over the Twins, allowing one hit.
The 23-year-old closer was in line for the victory once Mike Zunino blasted a go-ahead two-run home run in the eighth, and he was able to successfully parlay that opportunity into his second win through an efficient 11 pitches. Diaz is in the midst of an impressive stretch in which he's compiled six scoreless efforts in seven appearances, along with a .194 wOBA, 1.13 ERA, .161 BAA and 0.88 WHIP across eight innings.
