PITTSBURGH -- It was for nights like this that the Brewers pushed all their chips to the middle of the table for Mike Moustakas and Yasmani Grandal.

It took nearly $30 million to land those one-year free-agent mercenaries at the start of the year, but the investment has been paying off. That was particularly true on Thursday, when Moustakas and Grandal each tallied four hits and combined for three home runs, and Moustakas set a season high with four RBIs in an 11-5 win over the Pirates at PNC Park.

“I think those have been two guys who have been really consistent for us all year offensively,” said manager Craig Counsell. “Moose has been a really solid, consistent presence. Yaz is the streaky hitter, and he’s on a really good streak right now.”

That sort of production is what led Brewers owner Mark Attanasio to declare, “The chips are all in now,” in Spring Training after adding Moustakas’ $10 million salary on top of the team’s $18.25 million commitment to Grandal. Thursday was a night to cash out. Milwaukee tallied 11 extra-base hits, one shy of the franchise record, and set a season high with 18 hits overall. Moustakas enjoyed his 10th career multihomer game, hitting a two-run shot with two outs in the first inning and a leadoff home run in the third, when Grandal followed with a homer of his own to open a 5-1 lead that would grow to 7-2 before the Bucs briefly made it a ballgame late.

But the Brewers kept hitting right through the ninth, when Lorenzo Cain's bases-clearing double highlighted a four-run inning and gave Cain four RBIs to match Moustakas. Each of the top five hitters in the lineup reached safely at least three times.

The last time the Brewers had at least 11 extra-base hits was right here in Pittsburgh, a 20-0 romp over the Pirates on April 22, 2010, when Milwaukee collected 25 hits, including 12 for extra bases.

“The goal,” said Brewers starter Chase Anderson, “is to get in the dugout and let those guys do their job.”

Moustakas handled much of the early work in the first meeting between the Brewers and the Bucs this season. He has 15 home runs in his first 216 plate appearances of 2019, compared to eight homers in 218 regular-season plate appearances after Milwaukee acquired him from Kansas City last July. Six of Moustakas’ home runs have come since May 10, the date he moved back to his natural position at third base in the wake of Travis Shaw's wrist injury.

“Moose has been in a really good place,” Counsell said. “We love the home runs, but the home runs are going to come when you see the opposite-field line drives. You saw a couple today. That’s what I think is different than last year.”

Moustakas expected better in his second stint with the Brewers. Like Grandal, he held out as long as possible in search of a multiyear contract, but when it wasn’t available, he went for the best fit.

That led him back to the Brewers.

“Last year, we were in a hunt, and I didn’t feel like I was performing up to where I should have been,” Moustakas said. “We did a phenomenal job last year of getting to where we got to. This year, I feel really good. I feel comfortable.”

Thursday’s power show came at the expense of Pirates starter Joe Musgrove, who entered the night as the best pitcher in the Major Leagues at avoiding the long ball. Musgrove had allowed two home runs in his first 59 innings for a rate of .31 home runs per nine innings, tops among qualifiers. The Brewers hit three homers before Musgrove recorded the first out of the third inning.

Grandal was on the way to a big night of his own. He was a triple shy of the cycle after the fifth inning, and settled for eight total bases and his first four-hit game in a Brewers uniform.

“What Yaz brings, this guy is an All-Star-caliber player,” Moustakas said. “A switch-hitter, who, from both sides of the plate, can do damage. Calls a great game. Does a great job behind the plate. He’s a huge addition. He lengthens this lineup a lot. He’s been on fire recently, and it’s fun to watch.”

Eleven of Grandal’s last 20 hits have gone for extra bases, including six home runs.

Moustakas is in a similar place; eight of his last 16 hits have gone for extra bases, including five home runs.

“A lot of sliders with two strikes over the heart of the plate, just not quality pitches with two strikes,” said Musgrove. “And good lineups will do damage.”
