Giants @ Pirates
I keep coming back to who's actually standing on the mound for San Francisco. Blade Tidwell has five starts on his record this season and his team has lost all five. Over his last three he's given up 12 earned runs in 15 innings with 8 walks, and his most recent outing was the worst of his career — three home runs and six earned to Arizona. His whiff rate has come in at 12% in two of his last three starts, and the sweeper he throws more than a third of the time got punished last time out. He puts the ball in the air more than he keeps it down, and today it's 83 degrees at PNC with the wind blowing out to left. The split is what seals it. Left-handed hitters have hit .292 with an .893 OPS and four homers off him; right-handers .182 with a .472 OPS. Pittsburgh's card today is Horwitz, Lowe, Cruz and Jacob Gonzalez from the left side plus Reynolds and Mangum switching. The Pirates are 54-42 against right-handed starters this season and 14-30 against lefties — this is the schedule slot they handle. Lowe carries a .900 OPS with 23 homers against righties, Gonzales .332 with an .830, Cruz an .842 OPS overall. And this specific nine is 25-for-69 in the series and 48-for-157 over the last week, with Gonzales, Cruz and Lowe all in the middle of hot stretches. Yes, Pittsburgh is running a bullpen game, and normally I'd fade that. Not this one. Lake Bachar opens on his eighth such assignment and has allowed two earned runs over his last 9.2 innings, with a curveball generating a 36.6% whiff rate and a .160 xwOBA. Behind him, this relief corps has been the strength of the roster — a 3.12 ERA over the last ten days across 34.2 innings — with Yates, Soto, Weaver, Montgomery and Ramírez all having sat two to four days. Montgomery hasn't allowed a run since late July. Weaver sits at a 2.58 ERA with a 0.96 WHIP. Dotel was brought up this morning for length. More to the point, a parade of arms is exactly the right format against this Giants lineup. Devers is genuinely locked in and I'm not pretending otherwise — .421 over a 10-game hit streak, 32 homers, homers in three straight. But he never sees the same pitcher twice today, and Pittsburgh already showed last night it will just walk him with the game on the line. Behind Devers and Eldridge, San Francisco is running out Whitcomb at a .454 OPS, Furman at .462, Koss at .510, Knizner on 27 at-bats, and Gilbert leading off at 1-for-14 over the past week. That's a lot of outs available. And the other bullpen is in worse shape, not better. San Francisco used five arms yesterday, Seymour on back-to-back days, with Perdomo having thrown 58 pitches Tuesday and Roxby 31. Their unit is at a 4.61 ERA with a 1.49 WHIP on the year and no set closer. Underneath it, the fundamentals line up the same direction: Pittsburgh at +26 run differential, San Francisco at -70. Pirates 22-17 in one-run games, Giants 12-25. Pittsburgh is 39-32 after a loss. Home team, day game, and the Giants are on the fourth game of a road trip with a flight to New York waiting. The Pirates offense outside that nine-run inning has been thin — 2.6 runs a game over the other nine of their last ten — and that's the honest risk here. But the price at -166 is asking for about 60% and I think the pitching matchup alone gets there. I'll lay it.
