Jorge Soler's HR earlier tonight.

He also lined a double off of the 3B's head.

Justin Upton-esque build, nice swing, some very obvious power...I can't wait until I see this guy against real competition.

Keith Law had this to say on his first couple of days:

Cuban outfielder Jorge Soler made his pro debut on Thursday night with the Chicago Cubs' club in the rookie-level Arizona League, the lowest level of organized baseball, with teams largely populated by teenaged prospects, rehabbers, and a handful of older organizational players. Already 20, he's old to be in this league, but given how long it has been since he faced live pitching, it's a reasonable place for him to start.

Soler, who signed a nine-year, $30 million dollar deal with the Cubs in June, only DH'd and had three at-bats before he was pulled for a pinch hitter -- you know, don't want to overtax the guy or anything -- and did at least get a chance to show how explosive his hands are at the plate. He loads his hands high and deep, but accelerates quickly enough to catch up to above-average stuff, even meeting a few balls out in front of the plate (perhaps because his timing is still off). He's balanced through the swing and should be able to generate power from his lower half. He grounded out twice but didn't run hard either time, although his strides are long and easy and he should be an above-average runner when he decides to show it. (His third at-bat was a hard lineout to the pitcher.) He's in very good shape and his body looks loose and athletic. This wasn't an ideal look since he didn't play the field and hasn't faced live pitching in ages, but at least some of the tools were on display -- and yes, I will go back in a week or so to try to see him in the field.
