San Francisco, sitting at 58-82 even after Thursday, is still without Willy Adames and a chunk of its infield, and it showed up on the field: the Giants managed just 2 runs and finished with fewer hits than Pittsburgh's deeper lineup.
Pittsburgh jumped out 2-0 in the first, added two more in the sixth to make it 4-0, and that was effectively the ballgame. San Francisco's only real push came on a 2-run seventh that pulled it to 4-2, but Pittsburgh answered right back in the eighth to restore the 3-run cushion and close it out 5-2. The Polymarket room's busiest stretch of the day came early, right around that first-inning flurry — a fitting spot, since the game's outcome was mostly decided by the time it got loud.
The two clubs had split the first two games of this set, with San Francisco stealing the middle game in a slugfest before Pittsburgh answered in the finale to take the series 2-of-3. For a Pirates team that's spent stretches of the summer treading water around .500, closing out a series against a last-place club at home is the kind of businesslike result that doesn't move the standings much but keeps the roster's confidence intact.
Both bullpens are running thin — Pittsburgh lost Yates on game day, and San Francisco is already without five relievers to injury — which made Thursday less a showcase of front-line pitching and more a test of who could survive with the depth they had left. Pittsburgh's answer was cleaner, and with September winding down, that kind of margin is about all either of these clubs is playing for right now.
