Sheffield, a 21-year-old left-hander who is ranked the No. 3 prospect in the Yankees’ farm system byMLBPipeline, tossed 4.2 innings on Friday. He struck out six batters, but allowed two runs and four walks. It was Sheffield’s second Triple-A start, as he was promoted from Double-A Trenton on May 3.
With Double-A, Sheffield completed five starts and posted a 2.89 ERA.
“He’s going to continue to develop, work on the fastball command. But when you go watch him pitch, he’s a competitor. He’s a type of guy that you almost have to just hold the reins back on him a little bit. When the game heats up, he’s so competitive that sometimes that plays against him… We all felt the Double-A experience was good for him. He obviously competed and was doing well there. So, it was good to see him move on.
“These young men will tell us [if they’re ready for the majors]. History says that there’s going to be need for a number of arms, so hopefully he puts himself in a position that he’s talked about. That left-handed power arm — and again, I’ve mentioned to you multiple times about investing in our own future — it’s really nice to see young kids here that we know are going to be part of the nucleus moving forward. So when they do struggle, we’re learning from those times. And like I said, they’re going to be part of the core as we move forward.”
