Some notes from a pair of Class A games I attended in the past week, beginning with a matchup between the Royals' and White Sox's high-A affiliates:

• The Wilmington Blue Rocks' lineup is down two bats of note following last month's promotion of Hunter Dozier. Shortstop Raul Mondesi Jr., who turned just 19 on Sunday, is struggling at the plate, which is not surprising given how young he is for the level. But he's making it worse with his incessant attempts to bunt for hits. He's doing it early in counts, so he's not able to work on pitch recognition or timing or just swinging the bat like you want a prospect to do. He's a plus runner, so bunting for hits would add value, but it shouldn't come at the expense of him learning to hit. I'd put a moratorium on him trying to bunt for any reason the rest of the year, forcing him to work on improving his approach and gaining consistency with his left-handed swing.

• Wilmington lefty Sean Manaea looked better than he did when I saw him in April, showing a more fluid delivery, better use of his legs and a little more velocity.
