Another day, another milestone for Mitch Keller. The Pittsburgh Pirates ace once again took the mound on Sunday against the Baltimore Orioles and was phenomenal. Just six days after throwing his first career shutout, Keller posted zeroes once more and with authority. Over seven innings, Keller struck out a career-high 13 batters, lowering his ERA to 1.91 with a .201 opponents batting average over his last eight starts.
