The 14th-ranked prospect in the D-Back system as per MLB, Fletcher is very small for an outfielder, but has an extremely good arm and is a strong fielder. While his offensive potential isn’t nearly as promising, it’s hard to argue with what he’s shown so far this season. Even if Fletcher’s ultimate ceiling is just a fourth outfielder in the bigs, he’s worth a short-term addition right now.

Consider that he’s tossed seven scoreless outings in his last nine tries, including no earned runs allowed through five June appearances. Patino still has a long way to go, but at the age of 23, is still someone worth tracking to see if he can return to the Rays in the second half as a potential multi-inning weapon.

Moreta had another strong outing on Friday (1 2/3 shutout frames), giving him eight scoreless games in his last nine tries. He’s already closing in on a career high in games pitched and has a nice record; other than a regression in his control, we’re really bullish on his upside.

A former two-way player, Lorenzen covered a lot of ground in the outfield because of his speed, but given his 93-97 mph easy heat, he was wisely moved into a full-time pitching role.
