Paul Goldschmidt has impressed after signing a long-term extension with the Arizona Diamondbacks in the offseason.

"He knows his strengths and he knows his weaknesses," a scout said. "He's tough to pitch to."

Goldschmidt is hitting .306/.404/.560 with nine home runs and 30 RBI in 37 games. He has 37 strikeouts and 23 walks.

Another scout noted that Goldschmidt isn't the typical right-handed hitting first baseman. He's not lumbering or unathletic.

"He's not giving away a single at-bat right now," he said. "He's unreal. He's so locked in. He's got monster power and now he's kind of understanding his game on a different level.

"He's seeing a ton of pitches. He wants to use the big part of the field and because of the big power he can still beat you. It's incredible."
