Keller (9-6) picked up the win Sunday against the Tigers, lasting seven innings and giving up just one run on three hits and three walks while striking out a pair. The start will wind up as his final assignment of the season, Jeffrey Flanagan of MLB.com reports. Keller retired the first nine batters he faced before allowing a short rally to start the fourth inning. A double play cut that rally short after just one run, and he remained out of serious trouble for the remainder of the outing. He'll finish the season with an excellent 3.08 ERA in 140.1 innings, a superb return for a Rule 5 draft pick.
Keller allowed four runs on four hits and one walk while striking out seven over six innings Monday against Pittsburgh. He didn't factor into the decision. Keller gave up a run in the third, a pair in the fourth and one in the seventh prior to exiting with a one-run lead. He tossed 71 of 109 pitches for strikes. The 23-year-old had been on a roll prior to Monday's outing, as he'd surrendered two or fewer runs in his previous six starts (1.85 ERA with 29 punchouts over 39 frames). He'll look to get back on track Saturday in Detroit.
Keller (8-6) allowed one run on four hits in a win over the White Sox on Tuesday, striking out six and walking two in seven innings. Keller allowed just one extra-base hit in Tuesday's contest and all six of his strikeouts were swinging strikeouts. He's now tossed three consecutive quality starts and over his last eight starts Keller is 4-2 with a 2.25 ERA. The young righty has brought his season ERA down to 3.04 and carries a 1.30 WHIP with 87 punchouts in 127.1 innings on the year. If the Royals stick to their current six-man rotation, Keller would be in line to take on the Pirates in Pittsburgh in his next start.
Keller (7-5) struck out four and picked up the win in Friday's 9-2 victory over the Orioles, allowing two runs on four hits and two walks over eight innings. The rookie finished up August in style, settling down nicely after serving up a leadoff homer to Cedric Mullins to win his third straight decision. Keller posted a 2.89 ERA, 1.18 WHIP and 31:11 K:BB in 37.1 innings over six starts on the month, giving him plenty of momentum heading into his next outing Wednesday in Cleveland.
Keller allowed two runs on six hits in a no-decision against the Indians on Friday, striking out five and walking one in five innings. He allowed just two extra-base hits and threw 60 of 96 pitches for strikes. In four of his last five starts, Keller has allowed two runs or fewer, and he's thrown six quality starts in 15 games started this season. The young righty has a 3.33 ERA and 1.35 WHIP to go with a 72:41 K:BB in 105.1 innings. His next start will come against the Orioles at home.
