MESA, Ariz. -- First impressions are a thing of the past for A's lefty Sean Manaea, who is now able to hone his craft during the spring season rather than prove it.
Fresh off a strong rookie season, Manaea took the mound in relief of rotation mate Kendall Graveman on Monday afternoon and put together two scoreless innings in the A's 5-4 victory over the Giants. Manaea used his changeup to record both strikeouts, whiffing Giants catcher Buster Posey for his final out to strand his lone baserunner of the day, Denard Span, who drew a one-out walk.
