Del Castillo’s Three-Run Homer Helps Diamondbacks Hold Off Brewers

What happened:

Watch the highlights:

The Arizona Diamondbacks beat the Milwaukee Brewers 4-3 on Saturday night, with Adrian Del Castillo’s three-run home run in the first inning standing as the decisive early swing, according to Yahoo Sports. Arizona did not need a flood of late scoring because the first-inning damage created enough margin to withstand Milwaukee’s push.

Merrill Kelly was credited with the win after going five innings. The result mattered personally within the game log because it was his first win in seven starts, according to the source. That does not automatically mean the underlying form has fully turned, but it does mark a break from a stretch in which starts had not ended with a win beside his name.

The ninth inning tightened the finish. Paul Sewald allowed Jackson Chourio’s 13th homer, cutting into Arizona’s lead, but he still completed the save. It was Sewald’s 20th save in 21 chances, a highly specific late-game marker that gives the Diamondbacks a clear positive from a game that became narrower than the early script suggested.

Why it matters:

Arizona’s win reads like a compact lesson in leverage. A three-run homer in the first inning changes how both teams play the rest of the night. The Diamondbacks had enough scoreboard control to let Kelly work through five innings and then hand the game to the bullpen structure. Milwaukee, by contrast, had to keep chasing after one early mistake became the largest swing of the game.

The source does not give full standings context, so the tournament implication should stay focused on confirmed competitive signals. Arizona got a one-run win against Milwaukee, protected an early advantage, and leaned on a closer who has converted 20 of 21 chances. Those are practical ingredients for staying competitive over a long schedule.

Tournament impact:

For the Diamondbacks, the most important confirmed development may be the combination of Kelly getting a win and Sewald surviving the ninth. Starting pitching confidence and late-inning reliability affect how a team manages close games across a series. Even without broader standings data, a 4-3 result is exactly the kind of game that tests whether a club can protect small margins.

For the Brewers, Chourio’s ninth-inning homer is the positive note from the supplied facts. It kept the game alive and gave Milwaukee late pressure, but the source does not describe additional rallies, defensive plays, or missed chances. The confirmed bottom line is that the comeback stopped one run short.

What to watch:

Arizona will want to see whether Kelly can build from this five-inning win after a seven-start stretch without one. Milwaukee will look for more than late power if it wants to reverse games where the opponent lands the first major blow.

Confidence:

Confirmed by the source: Arizona won 4-3, Del Castillo hit a first-inning three-run homer, Kelly went five innings and won for the first time in seven starts, Sewald gave up Chourio’s 13th homer but earned his 20th save in 21 chances.
