Chicago Cubs first base prospect Jonathon Long is making noise at Triple-A, slashing .317/.399/.505 with 14 home runs and a 19.9% strikeout rate. The 23-year-old's bat has been his calling card, though defensive struggles at left field and third base have likely cemented him at first. Long could earn a call-up if he keeps hitting when rosters expand in September. While not a household name, his offensive profile is worth monitoring in deep dynasty and NL-only formats. Long's blend of contact and power makes him one of the Cubs' most intriguing under-the-radar prospects this season.

Last summer, Long spent time between High-A and Double-A, posting a cumulative .283/.391/.461 slash line with 21 doubles and 17 home runs. If Long can continue to produce at Iowa, he should be in the mix to join the major league roster during the stretch run.
