Oakland Athletics relief pitcher Sean Doolittle picked up his 40th, 41st and 42nd strikeouts of the season in Friday's 4-3 win over the Baltimore Orioles, thus becoming the first pitcher since 1900 to record his 40th K in a season before his second walk, per ESPN Stats & Info via Elias Sports Bureau.

Doolittle turned in a typically dominant performance Friday night, striking out Chris Davis, J.J. Hardy and Steve Pearce on just 12 pitches to earn his eighth save of the year. He hasn't given up a run since April 26, when he allowed four in an ugly appearance against the Texas Rangers.

Despite finishing April with a 5.68 ERA, Doolittle now carries a 2.48 mark to complement his ridiculous 42:1 strikeout-to-walk ratio. The A's closer-by-committee appears to be a thing of the past, as Doolittle has turned into the full-time stopper with four saves already in June.
