One thing first, before this turns into a pile-on: Mason Miller did not lose this game.
The San Diego Padres fell 7-6 to the Kansas City Royals on a walk-off in the 10th inning. The shape of that loss says plenty.
Miller walked into a mess in the bottom of the ninth of a 3-3 game: bases loaded, nobody out. He struck out Josh Rojas, Lane Thomas and Vinnie Pasquantino in order to get out of it clean. That's not a collapse, that's the best work anybody did all night. Royals Review pointed out Miller came in with an ERA under 1.00 and nearly two strikeouts an inning, with early Cy Young chatter already following him. He earned every bit of that outing.
So who actually lost this one? The soft middle of the Padres' operation.
San Diego did the hard part. In the top of the 10th, Miguel Andujar doubled home the automatic runner, his third double of the night, Fernando Tatis Jr. added an RBI single, and Xander Bogaerts lifted a sacrifice fly to make it 6-3. Take a three-run lead into extra innings and you're supposed to close that out. Simple as that.
Then Kyle Hart came in. Michael Massey singled home a run. Isaac Collins pushed another across on a groundout. And Carter Jensen ripped a two-run single through a drawn-in left side to end it. Hart (0-2) took the loss; Lucas Erceg (4-3) got the win despite giving up those go-ahead runs. Fine. But the pitcher of record only tells part of it. What happened underneath is worse.
Both of San Diego's runs in regulation came off a Royals defensive gift, a Massey fielding error on a Luis Campusano grounder in the fifth, and Kansas City's tying run in the sixth came right back on a Bogaerts throwing error to second. Sloppy game on both sides. The difference is the Royals cleaned theirs up when it counted and the Padres didn't.
Here's my honest read on it, and I'll say plainly this is opinion: this is a talented roster that can build a three-run lead in the 10th and still can't be trusted to shut the door. The starters weren't the issue. Michael King ground through 97 pitches and allowed just one run on a Lane Thomas homer, and Seth Lugo turned in a real bounce-back for the other side. The problem sits in the connective tissue: bullpen depth and glove work when the moment gets biggest.
Now the fair caveat, because I won't pretend otherwise. This was the opener of a three-game set at Kauffman Stadium, and things didn't sit still after it. The Royals won the next game too. Then this same Padres offense turned around and blew Kansas City out by a wide margin two days later. So don't treat this walk-off as some verdict on San Diego's character. The form has been shaky, not settled.
But a team that entered that Friday night sitting right around .500, third in a crowded NL West, can't keep handing games to a club with a losing record and expect the math to work out. You win the games you're supposed to win. The Padres didn't. And it wasn't the closer's fault.
