In MLB Pipeline's most recent 'not a mock draft' where they pick guys in the order that they like them, Matt McClain was picked at #13. He doesn't have the tools that I'd want (and he's injured), but the list highlights for me that there could be some exciting guys left at #13. One guy left available in that theoretical was Texas RHP Tyler Madden- I love that guys stuff and delivery. He seems to be running into a wall recently that a lot of the top guys are after missing last season.
One guy working is way back up the list is U. of Florida center fielder Jud Fabian. After starting the year with a 43% strikeout rate during his first 107 ABs, he's made some changes to reduce it to 21% over the last 84 ABs. He's done well in two summers of wood bat collegiate leagues, and if he's not leading D1 in homers, he's close.
I know you don't draft for need, but if they don't go after an arm, I'd really like to see them start to get some OFs who can impact the ball and play center. Fabian at this point seems to be a Joc Pederson clone- but a centerfielder who can put up Pat Burrell like numbers with 800 ops and .240 batting average, I wouldn't be upset by that right now.
The perfect guy for them is Boston College CF Sal Frelich- that guy has polish, tools, and is a sparkplug, but he won't be there for them.
