PHOENIX -- Christian Walker has regained his power stroke, and it couldn't have come at a better time, with David Peralta hitting the injured list.

Walker had three hits in his first career two-homer game to help the D-backs recover from a pair of walk-off losses to the Dodgers with an 8-0 victory over the Rockies on Friday. The win also ended the D-backs' eight-game losing streak against the Rockies.

Walker broke a scoreless tie by hitting a 1-0 fastball from Rockies starter Antonio Senzatela for a two-out, two-run opposite-field homer in the fourth inning. To that point, Senzatela had battled Zack Greinke (10-3) evenly through three innings.

Walker then capped the D-backs’ six-run fifth inning with a two-out, three-run homer into the seating area over the 25-foot wall just to the right of the batter’s eye in center field. Walker hit the first pitch he saw from reliever Jesus Tinoco, a shot that was measured at 431 feet.

“I was definitely ready for a fastball,” said Walker, who turned around a 96 mph four-seamer. “Something told me breaking ball, but they stuck with the fastball. Luckily, it was over the middle of the plate."

Walker also homered off Walker Buehler in Wednesday’s 5-4, 10-inning loss to the Dodgers and has four homers in his last seven starts. He is third on the team with 17 homers while again showing the pop that marked his first month in his first season as a regular.

Walker, hitting .263 with a .505 slugging percentage, set a team rookie record with seven homers in March/April. He also led NL rookies in hits, batting average and doubles, a stretch that stood to show he does not just hunt home runs.

“Obviously, home runs are great and you want to hit homers,” Walker said. “But it terms of my approach and my game swing and my ‘A’ swing, I wouldn’t say I am trying to hit home runs.

”They tend to come in bunches. It could be the pitches I am hunting. It could be where guys are throwing them. Maybe I am swinging a little more uphill than I normally do, but homers come and go. Just trying to stay consistent in terms of average and barreling balls.”

Walked has adjusted since running into a dry spell that included one homer in a 28-game stretch that ended in late May, when Arizona manager Torey Lovullo said he saw some frustration.

“I have high expectations for myself,” Walker said. “I expect a lot of myself. I know what I am capable of and I want to show it night in and night out. When I don’t perform the way I should, I get frustrated.

“At the same time, you have to be fair to yourself. You are going to fail more than you succeed. It’s just handling it and rolling into the next day and building one at-bat at a time.”

Another 10-win start
Greinke, who fanned nine batters over seven scoreless innings to earn the win on Friday, joined some select company with his victory.

Greinke became the fourth pitcher in the Wild Card era (since 1995) to post 10 victories in at least four consecutive seasons prior to the All-Star break, according to STATS, LLC. He joins Roy Halladay (seven), Max Scherzer (six) and Greg Maddux (five).

“Been playing on some good teams that last eight, 10 years, it seems like,” Greinke said. “That helps a lot.”

Greinke’s streak began when he joined the D-backs in 2016.

Scherzer’s current streak will end this season. He is 8-5 entering his scheduled start against Kansas City on Saturday.
