Pittsburgh Pirates Betting Preview
The Pittsburgh Pirates (38-52, 12-31 Away) swept the New York Mets and St. Louis Cardinals, and were on a six-game winning streak, but that positive streak ended with a couple of losses to the Mariners. Pittsburgh failed to score in those defeats. In last night’s 1-0 defeat, Mike Burrows pitched for 5.0 innings in a no-decision, allowing no runs on three hits with six strikeouts and four walks. Caleb Ferguson took the loss.
This year, the Pirates average 3.48 runs per game (28th in the MLB) on a .234/.306/.345 triple-slash. When it comes to pitching, the Pirates’ staff has a 3.66 ERA (8th) and 1.19 WHIP (4th). Bryan Reynolds leads the Pirates with a .232 batting average, ten home runs, and 45 RBI this season.

The Seattle Mariners (47-42, 24-21 Home) are without a loss in the previous four series and added one more series win after beating the Pirates in the first two games. Before it, they defeated the Cubs, split with the Twins, beat the Rangers, and split with the Royals. Seattle secured a minimal 1-0 victory on Saturday. Ben Williamson drove in the game-winning run, while Luis Castillo got the win after allowing no runs on two hits with eight strikeouts and no walks across 7.0 innings of work.
This season, the Mariners average 4.55 runs per game (13th in the MLB) on a .248/.323/.408 triple-slash. When it comes to pitching, the Mariners’ staff has a 3.85 ERA (15th) and 1.26 WHIP (15th). Cal Raleigh leads the Mariners with a .270 batting average, 35 home runs, and 74 RBI this season.

Mariners vs Pirates Prediction
The Mariners won seven of the previous ten H2H encounters, including the last three. I am backing Seattle to win again and complete a series sweep, even though Paul Skenes starts for the Pirates. Skenes’ biggest problem is his inefficient offense, so even if he secures another quality start, I doubt the Pirates will outscore the M’s. George Kirby, on the other hand, recorded back-to-back quality starts and allowed just two runs in 12.0 innings, so I am backing him to display another strong outing here. Go with the Mariners.
