Nuñez cops to coasting

Madison Bumgarner was not the only Giant to ’fess up this week.

Eduardo Nuñez ,nowa super-utility player with Christian Arroyo’s arrival, said Tuesday that he was wrong for not running out some groundballs, one of which might have cost the Giants a chance to beat the Rockies.

Nuñez also said he is still somewhat uncomfortable playing left field, but he expects that feeling to improve and he was happy to step aside for Arroyo.

In the April 13 opener of a four-game home series against the Rockies, who were leading 2-0, Nuñez led off the fifth inning with a one-hopper to third baseman Nolan Arenado, who was playing in. Nuñez jogged out of the box as Arenado held the ball momentarily.

When Nuñez finally sped up, Arenado made a wide throw that first baseman Mark Reynolds had to dive to catch. An “out” call was sustained by replay, the Giants went down 1-2-3 and lost the game 2-1.

Nuñez also did not run out a grounder in Kansas City last week.

“No excuses. You have to run hard on every single ball,” Nuñez said.

Asked if the coaching staff talked to him about it, he said, “They don’t have to. I know what I’m supposed to do.”

Asked about moving from third base to left field, Nuñez said, “Whatever the team needs is the bottom line. The team is better with Arroyo. He’s a great player . ... I’m a little uncomfortable (in left). That’s normal. The more playing time I have, the more confidence I’ll feel.” Crawford to be away: Brandon Crawford will begin an absence Wednesday so he can join his wife, Jalynne, for the viewing and funeral for her sister Jennifer in Southern California.

The Giants could have Crawford back for Friday’s game against San Diego if they don’t formally place him on bereavement leave, which must last three games. In that case, they would not be allowed to replace him on the roster for Wednesday’s and Thursday’s games, and manager Bruce Bochy said the club needs another player because it already is short with Denard Span hurt. Crawford’s groin injury in the eighth inning Tuesday might have made the issue moot.

Perfection: Domenic Mazza, who was born in Walnut Creek and attended Clayton ValleyConcord, threw an 85-pitch perfect game for the Giants’ low Class A Augusta, Ga., team in a 9-0 win at Lexington, Ky., on Tuesday. It’s the first perfecto in South Atlantic League history.

Mazza, 22, now has something to be known for besides allowing an Opening Day homer to Tim Tebow. Mazza was the Giants’ 22nd-round pick in 2015.
