Will Harris was clearly the best waiver claim in the Jeff Luhnow era. Harris was named an all-star in 2016 and took over the closer role down the stretch before the all-star break. But the good times were over as Harris blew his last two save chances and three of his last five.
Astros manager A.J. Hinch named Ken Giles as the team's closer going forward before Tuesday's game against the Blue Jays.
Giles, 25, was the Astros' biggest acquisition of the offseason as Houston traded top prospects Vincent Velasquez, Mark Appel, and Tom Eshelman for a played billed as the Astros future closer.
Giles didn't start the 2016 season strong. He was 0-2 with 9.00 ERA in his first 11 games. But Giles has been the Astros' best reliever of late. He has allowed zero earned runs in 13 1/3 innings, six hits allowed, four walks, and 23 strikeouts.
