Griffith, a left-handed hitting outfielder, played three years at Saint Mary's, where he hit .300/.450/.437. This past year, he hit at an even better rate, with a 1.022 OPS, and he hit five home runs. He hit three in his first two years of college. He's also shown the ability to steal some bases as well, stealing 43 bases over his three years at Saint Mary's.

He announced that he transferred to TCU, but the Royals will look to get him to start his professional career and forgo his final year of eligibility. Griffith will add to the outfield depth, as he played all three outfield positions while in college.
