MLB Pipeline ranks Jesús Luzardo and A.J. Puk as the A's top two prospects, as well as the No. 2 and No. 4 left-handed pitching prospects, respectively, in all of baseball.
Unfortunately for Oakland, both southpaws have dealt with arm injuries, delaying their major league debuts. Puk, 24, had Tommy John surgery last April, and Luzardo, 21, was shut down with a shoulder strain this March.
Now it appears there's finally reason for optimism. According to Athletics Farm, A's minor league pitching coordinator Gil Patterson expects the two lefties to begin pitching in games late next month.
