PHOENIX -- It took them three months, but the D-backs have got things rolling in the right direction.

The latest example came Saturday night when they got another strong pitching performance by rookie right-hander Yilber Diaz and a pair of homers from Corbin Carroll to beat the Blue Jays, 12-1, at Chase Field.

The win was the fourth in a row for the D-backs, who moved two games above .500 (49-47), matching their highwater mark for the season they set back on April 2.

The four-game winning streak also matches the longest of the year, and Arizona is guaranteed to go into the All-Star break with an above .500 record. That’s quite the achievement for a team that was seven games under at one point and has suffered injury after injury particularly with their starting rotation.

Left-hander Jordan Montgomery is scheduled to return after the break and left-hander Eduardo Rodriguez and righty Merrill Kelly should return in early August. The D-backs have already gotten outfielder Alek Thomas and shortstop Geraldo Perdomo back from extended stints on the injured list.

“I think, obviously, we've still got to play tomorrow, but when I think of coming back from the break and a couple of our arms getting healthy, I’m really excited to attack the second half with these guys,” said Carroll. “I think we all knew that we were capable of doing something like this, but to see it play out the way it has, it's been pretty rewarding. I think everyone just wants to keep this thing rolling.”

After a sluggish start to the season, Carroll has picked things up. He was demonstrably upset when he popped up in the fifth inning but responded by hitting a three-run homer in the seventh and a two-run blast in the eighth.

“Yeah, there was a pretty good yelling session there in the outfield,” Carroll said with a smile. “But you know we've been working really hard and to see a couple swings pay off tonight, that’s great. I still think that there's a lot of work to do but it just makes it a little easier to keep moving forward when you see some results behind it. We're going to just keep attacking.”

Speaking of attacking, that’s what Diaz does. The 23-year-old has impressed his teammates with his ability to continually attack the strike zone and not be overwhelmed by the moment.

Diaz made his Major League debut last Monday against the Braves and allowed one run over six innings. Saturday against Toronto, he allowed one run over six innings again, but this time picked up his first career win.

“He's going right at guys from pitch one, his first day here,” Carroll said. “It's really fun to play behind. Two good breaking balls following up his fastball that looks like it’s got some life on it and really gets on guys.”

D-backs manager Torey Lovullo said what impressed him most about Diaz’s start Saturday was that, unlike in his debut, he didn’t have his best stuff.

That didn’t seem to faze Diaz. He credited it to a practice he does the night before every start.

“One thing that helps is I visualize the outings the night before,” Diaz said via interpreter Rolando Valles. “That’s one way for me to slow things down.”

Right now, it appears, there’s no slowing down the D-backs.
