Carlos Narváez hasn't just been a pleasant offseason addition for the Red Sox. He's been arguably one of the best rookies in baseball.

5) Carlos Narváez threw out Anthony Volpe, the extra-inning automatic runner, at third base for the first out of the 10th inning. He initially was called safe but the Red Sox challenged and the call was overturned. Narváez has thrown out three of four runners who have tried to steal against him the past two games.

Factoring in his two hits in Sunday’s win for Boston, Narváez is now hitting .282 with a 128 wRC+. Mariners star catcher Cal Raleigh, who leads MLB in home runs, is the only qualified backstop in the American League with a higher OPS (1.173) than Narváez (.834). He could’ve been the perfect right-handed platoon option with Wells this year.
