Week 14 of fantasy baseball introduces several undervalued players primed for roster spots. Alejandro Kirk, the Toronto Blue Jays' catcher, is proving his worth with a .306 average, 39 RBIs, and an impressive .429 OBP over his last week of games. Ceddanne Rafaela of the Boston Red Sox has shown significant improvement, lowering his strikeout rate and contributing with a .305 average this season. Nathaniel Lowe, now with the Washington Nationals, is heating up with 27 home runs projected this season, enhancing his value despite a slump in previous years.

Sal Frelick, an emerging star for the Milwaukee Brewers, is showcasing impressive plate discipline while maintaining a solid .300 batting average. Lastly, Trevor Story is making a comeback for the Red Sox, hitting well lately, giving deeper leagues a potential boost. These players represent great opportunities for managers looking to boost their lineups.
