Seattle Mariners starting pitcher Chris Flexen threw five solid innings against the Diamondbacks Tuesday. For the first time this spring, Flexen did not allow a run, yielding only three hits and one walk while striking out four. Flexen now sports a 6.23 ERA with 15 strikeouts over 14 spring innings. Tuesday's outing showed off Flexen's upside, offering high strikeout rates while limiting hard contact. He starts the season as a streaming option for fantasy managers.
