救援
Save Situation

A Relief Pitcher is in a Save Situation when upon entering the game with his club leading, he has the opportunity to be the finishing pitcher (and is not the winning pitcher of record at the time), and meets any one of the three following conditions:

1.he has a lead of no more than three runs and has the opportunity to pitch for at least one inning, or
2.he enters the game, regardless of the count, with the potential tying run either on base, at bat, or on deck; or
3.he pitches three or more innings regardless of the lead and the official scorer credits him with a save.

上場時球隊領先, 最後完成比賽的投手, 且不是紀錄上的勝投(如果是後援上來拿勝投, 只記勝投), 並符合下列三項其中一項:
1.領先三分內(含三分), 至少投滿一局.
例(1)今天水手領先三分時, 救援投手 Putz 上場投第九局, 維持領先到終場, 拿到救援點

例(2), 遊騎兵的 Bauer 第7局上場, 當時是5比3領先, Bauer 投了 2.1 局到終場, 雖然最後遊騎兵10比3大勝, 但上場時符合救援成功條件, 仍算救援點.

2.不管分數, 後援進場時, 壘上跑者, 打擊者, 或下一個打擊者, 是追平分的話
例(1) 天使 7:4 領先3分, Rodriguez 上場時, 兩人出局, 1,3壘有人, 打者就是追平分, 所以雖然只投1個出局數(未滿1局), 仍有救援點.

3.後援3局或3局以上

中繼點
Hold

A Hold is credited any time a relief pitcher enters a game in a Save Situation, records at least one out, and leaves the game never having relinquished the lead.

Note: a pitcher cannot finish the game and receive credit for a Hold, nor can he earn a hold and a save.

上場時的情況, 符合救援的情況, 至少解決1個人次, 下場時, 球隊保持領先.
例(1) 教士7局上, 7比5領先, 二壘有人, Meredith 上場時, 投1局, 領一個中繼點.

例(2) 洋基4:2領先, Myers 上場, 解決1人次, 有中繼點, 後面解決2人次的 Proctor, 也有中繼點.

例(3) 今天的比賽, 任何一個投手只要上來有解決1人次, 保持洋基領先, 都可以拿中繼點.
