The A's best starter just walked off the mound at 67 pitches, and nobody knows when he's coming back.

Jeffrey Springs Exits with Hip Injury, Leaving Oakland's Rotation — and Team Totals — in Limbo

As MLB.com reported, Jeffrey Springs left Thursday's start against Kansas City after completing three innings, accompanied by the team trainer and later diagnosed with right hip soreness. He threw just 67 pitches before exiting — a number that signals the A's weren't taking any chances. Oakland entered the day sitting atop the AL West, and Springs has been a significant reason why.

Springs came into this start with a 3.79 ERA and a 3-0 record through his first four outings, posting a sparkling 1.46 ERA in that stretch before cooling off over his last two appearances. He's been Oakland's most reliable arm in a rotation that has carried a young, transitional roster to genuine contention. The timing of this injury couldn't be worse — his next scheduled start would come Tuesday at Citizens Bank Park against the Phillies, one of the National League's most dangerous lineups.

The immediate question is severity. Hip injuries in pitchers are unpredictable; what presents as soreness can resolve in days or linger for weeks. Oakland has Triple-A options in top prospects Gage Jump (MLB's No. 49 overall prospect) and Kade Morris, plus Joey Estes, but none of them carry Springs' track record or command profile. Plugging in a prospect against Philadelphia is a vastly different proposition than working him in against a weaker opponent.

From a betting standpoint, this development has real implications for Oakland's team totals going forward — but the more immediate angle is the upcoming Philadelphia series. A Springs absence means the A's are likely running out a debut-caliber arm against a Phillies lineup that punishes left-handed pitching and ranks among the top offensive units in baseball. That tilts the Phillies' team total upward and makes Oakland's side of the over/under more volatile. For tonight's game, the A's bullpen absorbing six-plus innings after Springs' early exit compresses their relief depth ahead of that Philadelphia trip, which adds another layer of risk.

Watch the Springs injury timeline closely before Tuesday. If he's officially ruled out of his Phillies start, lean toward the over on Philadelphia's team total and consider the Phillies' run-line value. On the Oakland side, without their anchor starter, first-five-inning unders become harder to trust until the replacement arm is confirmed and scouted.
