Mantiply did not retire a batter and gave up three runs on three hits in Wednesday's 5-3 loss to Kansas City.
Mantiply entered a tied game with a runner on first and let the game get away, allowing two singles and a three-run home run. He's pitched effectively when starting a clean inning, but he has allowed 10 of 24 inherited runners to score (42 percent) this year. One might think the left-hander would be better at preventing inherited runners from scoring, given Mantiply sports a 2.66 ERA, rarely issues walks (0.7 BB/9), keeps the ball in the park (0.7 HR/9) and does a good job stranding his own runners (76.6%).
