Frequently asked
What are probable pitchers?+
A probable pitcher is the starter a club expects to use in an upcoming game. Clubs typically announce one to five days in advance, and listings can change up to first pitch — most often because of rest, weather or a roster move.
How often does this page update?+
The timestamp at the top is when PitcherStat last refreshed this slate. Listings can still change if a club names a new starter.
What does TBD mean?+
TBD means the club has not announced a probable starter yet. PitcherStat does not infer or guess a starter before a reliable announcement is available.
Who has the highest P-Score on this date?+
Trey Yesavage at 53. P-Score is our 0–100 season-strength index for starters.
Are the lineups official?+
Not yet. The lineup column shows official only when that club has posted an order. Projected means recent usage; pending means no order is available.
