Jordan Montgomery
If there is one lefty veteran who might still be in the Pirates’ price range and would be a major rotation upgrade, it would be Jordan Montgomery. Monty has a 3.46 ERA, 3.63 FIP, and 1.23 WHIP. His 21.2% strikeout rate and 6.5% walk rate are both nearly in line with his career averages.
But his 0.87 HR/9 rate has been the best of his career thus far. The lefty is basically pitching to his career norms and has consistently been both solid and durable. If I had to choose one free agent to go atop of my Pirates FA wishlist, it would be Montgomery.
