Blach’s gift to his father

DENVER — The Giants lost an ugly one Sunday, but Ty Blach will remember the good parts of the afternoon.

“That was pretty special, especially because it’s Father’s Day,” Blach, a Denver native, said of his first Coors Field start. “I came to so many games as a kid here with my dad and mom. It was pretty neat to be able to celebrate that.”

With a bunch of family and friends in attendance, Blach took a 2-1 lead into the seventh inning before surrendering two home runs and exiting. Hunter Pence’s homer in the ninth put the Giants ahead, but Nolan Arenado hit a walk-off homer against closer Mark Melancon.

Blach’s parents, Randy and Karen, saw it all.

“My dad and I spent countless hours out on the field, taking extra batting practice, getting extra swings, taking me to pitching lessons, whatever it was,” Blach said. “He was right there for me supporting my dream. So that was pretty special to be able to kind of give back to him today.”

Blach made his big-league debut at Coors Field in September, out of the bullpen, and made another relief appearance here in April, before he replaced Madison Bumgarner in the rotation.

Pitching a mile above sea level was nothing new for Blach. He grew up at altitude, a 2009 graduate of nearby Regis Jesuit High School.

“Ty did a terrific job,” manager Bruce Bochy said. “He threw a great game for us. It’s a shame we couldn’t get him a win.” Briefly: Bumgarner’s next simulated game will be Wednesday in Arizona . ... Jarrett Parker (shoulder) will begin his minor-league rehab assignment Monday with Triple-A Sacramento . ... Arenado has four career walk-off hits, and the Giants are three-time victims . ... Arenado was the 31st player in history whose walkoff homer completed a cycle.
