Kansas City has an argument behind Michael Wacha, while Pittsburgh’s stronger bullpen numbers complicate the price.
The Kansas City Royals visit the Pittsburgh Pirates at PNC Park on September 20, 2026, with first pitch scheduled for 1:35 p.m. ET. MLB.com lists Michael Wacha and Lake Bachar, both right-handers, as the probable starters for this 2026 MLB matchup.
Wacha enters with a 9-9 record, 3.34 ERA and 149 strikeouts. His August 28 outing against Cleveland illustrates his upside: eight scoreless innings, four hits, 10 strikeouts and no walks. That performance supports his ability to work deep into a game, although one outing cannot establish today’s advantage.
Bachar carries a 1-4 record, 3.50 ERA and 86 strikeouts. Covers lists an average of two innings across his last five appearances. That suggests Pittsburgh could need substantial relief coverage, but it does not confirm his planned workload today.
Pittsburgh’s season bullpen figures are stronger: a 4.10 ERA and 1.32 WHIP against Kansas City’s 5.03 ERA and 1.50 WHIP. The Royals’ active bullpen also allowed 13 earned runs across 15⅓ innings in its last three-game sample. Those numbers weaken the case for backing Kansas City solely on Wacha.
Pittsburgh won Saturday’s meeting 6-5. Kansas City received four hits from Nick Loftin, three from Bobby Witt Jr. and a Carter Jensen homer. That production offers some encouragement for the Royals, but a single game provides limited evidence for projecting Sunday’s scoring.
SportsJaw lists Kansas City moneyline -120 and Pittsburgh moneyline +108, with over 8.5 (-105) and under 8.5 (-115). The pitching evidence points in competing directions, and the available offensive information does not establish a convincing total. Pass, with no winner or score projection.
