Pittsburgh is the 57c moneyline favorite over Detroit for the August 19, 2026 rubber game at PNC Park (58c Kalshi, 56c Polymarket), with Detroit at 44c on both books. The edge is entirely the mound: Paul Skenes (9-11, 3.88 ERA) against Jackson Jobe, who has two starts and a 6.23 ERA on the season. Pittsburgh is 62-66, Detroit 61-65, and the series is tied 1-1 after a split of the first two games.
The Pirates close a split interleague series as the 57c favorite at PNC Park on Wednesday, August 19, 2026, and the reason is on the mound. Paul Skenes starts for Pittsburgh opposite Jackson Jobe, who is making his third appearance of the season for Detroit. Neither club is in playoff position, Pittsburgh at 62-66 and Detroit at 61-65, so this board is priced off the starting pitchers rather than off standings leverage. The two books sit 2c apart on the favorite and the live odds board above carries the current numbers on each.
Tigers vs Pirates Market Context
Pittsburgh is 62-66 and fourth in the NL Central, 33-32 at PNC Park. Detroit is 61-65 and third in the AL Central, and the road split is the problem: 29-34 away from Comerica Park against 32-31 at home. Both clubs are 5-5 over their last 10, which is why this moneyline prices closer to a coin flip than the standings alone suggest.
The series is tied. Detroit took the opener 8-5 on August 17 and Pittsburgh answered 4-1 on August 18, so the 12:35 PM ET first pitch Wednesday is the rubber game and the getaway game of the set.
The board holds $17.0K in lifetime volume across Kalshi and Polymarket and every line on it is verified two-book. The distribution is the interesting part. About $7.8K sits on the moneyline and $10.1K sits on the single first-inning line, where Kalshi alone carries $10.0K. Traders on this game are more interested in whether a run scores in the first inning than in who wins it.
Cross-platform, the books are close to agreement. Pittsburgh is 58c on Kalshi and 56c on Polymarket, Detroit is 44c on both. A Pirates buyer gets the better entry on Polymarket by 2c; the Detroit side prices identically either way. Kalshi's two moneyline legs sum to 102c against Polymarket's 100c, which is the vig showing up on the Kalshi book rather than a disagreement about the game.
The line has barely moved. Across the overnight snapshot series Pittsburgh went from 57c to 58c on Kalshi and Detroit held between 43c and 44c the whole way. This is a held line, not a steamed one, and the Pittsburgh Pirates hub shows the same flat read across the rest of their board.
Tigers vs Pirates Pitching Matchup
Paul Skenes takes the ball for Pittsburgh at 9-11 with a 3.88 ERA across 25 starts. The record understates him and the recent trend complicates him. He carried a 2.62 ERA as late as May 17 and has allowed 15 earned runs over his last five starts covering 26.1 innings, a 5.13 clip. His most recent outing, August 11 at Miami, was a return to form: 5.0 innings, five hits, one earned run, four strikeouts on 65 pitches. Wednesday is his first start in eight days.
Jackson Jobe answers with two starts and a 6.23 ERA on the season, and those two outings sit at opposite ends of a range. On August 8 at San Francisco he threw 5.0 innings and allowed one hit and no runs on 71 pitches. On August 14 against the White Sox he was hit hard: 3.2 innings, nine hits, six earned runs, two home runs, 74 pitches. Detroit has not pushed him past 74 pitches in either appearance, which hands the middle innings to the Tigers bullpen and is the strongest argument for a 44c price rather than something closer to even.
The first-inning market reads the matchup the same way. A run in the first is 48.5c (48c Kalshi, 49c Polymarket), a coin flip against a Skenes start, which is a live number and is consistent with Jobe's short leash.
When the Tigers vs Pirates Market Resolves
The market resolves on the final score of the game at PNC Park on Wednesday, August 19, 2026, first pitch 12:35 PM ET. The moneyline pays the winning club's contract at $1 per share and the losing club's at $0, with no draw outcome in baseball, so extra innings settle to the eventual winner. The separate first-inning contract resolves YES if either team scores at least one run in the top or bottom of the first. Both Kalshi and Polymarket settle off the official final once the game goes final, normally within a few hours of the last out.
Key Tigers vs Pirates Catalysts
- Skenes rest: Pittsburgh's ace makes his first start in eight days, carrying a 3.88 season ERA and a 5.13 mark over his last five outings.
- Jobe's leash: Detroit has capped Jackson Jobe at 74 pitches across both of his starts, so the Tigers bullpen is on the hook for four innings or more.
- Rubber game: the series is 1-1 after Detroit's 8-5 win on August 17 and Pittsburgh's 4-1 answer on August 18.
- First-inning depth: the run-in-the-first line at 48.5c holds $10.1K, more volume than both moneyline legs combined.
- Book spread: Pittsburgh is 2c cheaper on Polymarket at 56c than on Kalshi at 58c, while Detroit prices at 44c on both.
- Season stakes: Detroit trades at 31c to reach the postseason and Pittsburgh at 7c, so neither side is playing for meaningful leverage in this one.
Related Tigers vs Pirates Markets
Detroit's season-long price is the better read on this club than any single game: the Tigers playoff market has them at 31c and the AL Central race has them third at 15c behind a 60c White Sox favorite. Pittsburgh's side of the ledger is thinner, with the Pirates playoff market at 7c and the NL Central race effectively decided at 81c for Milwaukee.
