WASHINGTON -- The Brewers have two new names on the lineup card, a veteran arm on the way to help the bullpen and, not insignificantly, a victory on what has been a rough road trip.

After adding lefty reliever Andrew Chafin at Tuesday’s Trade Deadline in the wake of earlier deals for first baseman Carlos Santana and outfielder Mark Canha, the Brewers rode a go-ahead, four-run fourth inning to a 6-4 win over the Nationals at Nationals Park to snap a four-game losing streak.

Canha went 0-for-3 but walked and scored a run in his Brewers debut, and Santana added to his defensive highlight reel at first base on a night the Brewers’ rookies led the way. Sal Frelick tallied two outfield assists including a big out at home plate to end starter Freddy Peralta’s long second inning before Brice Turang and Joey Wiemer each delivered two-out, two-run singles during the decisive fourth.

It was the sort of move-the-line inning the Brewers hope to produce more of with the Trade Deadline behind them.

“My phone has been charged multiple times just today, so we’ve been busy,” said general manager Matt Arnold after making three trades on Tuesday, acquiring Chafin in addition to two Minor League pitchers in swaps with the Red Sox (for longtime Brewers infielder Luis Urías) and Rays. “Our whole staff has been busy. We were in play in as many ways as possible to help this team. Ultimately, these are the deals we were able to consummate, and certainly we’re happy about those.”

The Brewers took on some payroll for all three of their additions, Arnold noted, and had the green light to add more if the type of “responsible” opportunities he’d been talking about in recent weeks presented themselves at the last moment.

The Trade Deadline passed just after a month of July in which the Brewers went a respectable 14-11 while pitching well (third of 30 MLB teams in WHIP, first in strikeouts) but remained in the bottom half of the league offensively. The Brewers were 17th in both runs per game and OPS in July. 

“Again, it’s not just offense, it’s a team as a whole,” Arnold said. “It’s a team that’s typically driven by pitching and defense, but adding some veteran bats and a veteran left-handed arm that’s proven to be successful in the big leagues is certainly something that we’re happy about.” 

Said Brewers manager Craig Counsell: “I think we added three very solid Major League players that all address places we could upgrade the team and still -- especially offensively -- leave us some flexibility here. At this time of year, players can still step up and perform. It still leaves us room to adjust to a player stepping up and performing.”

That certainly applies to the addition of Canha, who was the designated hitter in his Milwaukee debut, allowing rookie Wiemer to continue to get at-bats and contribute in center field, where he leads Statcast’s fielding runs metric. But Canha will also make some starts in right field, pushing Frelick to center on those days and allowing Counsell to use the DH to get catcher William Contreras or left fielder Christian Yelich off his feet.

“I’m excited to be here, excited to make a playoff run with this talented group,” Canha said. “It's a lot for me because I have never been traded before [in the Majors]. So it's a new experience and I'm excited for this chapter in my career.”

For Canha and players across baseball, there’s a sense of relief to the Trade Deadline having passed.

“I think around this time of year, there's a lot of uncertainty and it happens to all of the teams that are going through it,” he said. “And sure, maybe it's a little heightened in New York. But I've been with Oakland for a lot of years, and it's not an easy time for any player or players’ families. It's a little unnerving.”

For GMs, it’s also a chance to exhale. From here on out, there are only limited ways to add outside players. Among them are waivers, free agents or trades of players who aren’t on 40-man rosters. 

“We certainly tried to add to our Major League club, and I hope that we accomplished that,” Arnold said. “I said this all along: Our guys deserve the support that we can give them, and I think adding veteran guys who have been through a lot of battles, in Canha and Santana and Chafin, hopefully accomplished that for us.

“I’ve heard it already from Craig and some of the guys in the clubhouse, we’re excited to see what we can do here in the second half.”
