Rangers vs. Pirates Odds & Betting Predictions - June 21, 2025

This is my way of backing Kumar Rocker and Mitch Keller to slow down two of the worst offenses in baseball this season. Rocker has not been good (7.31 ERA) but his xERA is 6.03 and several season-long projection systems have him closer to a mid-4’s ERA pitcher. He’s coming off five scoreless innings against the White Sox and is -170 for u2.5 earned runs so I’m hoping he’s turned a corner. I’m also willing to back Keller, who has a 4.08 ERA but a 3.91 xERA and is allowing the fewest home runs so far in his career (0.61 HR/9). Rangers and Pirates have ranked among the bottom-five on offense this season, averaging just 3.63 and 3.21 runs per game respectively. I considered u8.5 for the full game but am going to target the F5 so we don’t have to involve the bullpens.
