He's super underrated and was a Top 40 player in this format in 2015. Deploy him strategically and you can win SB almost every single week without destroying your ratios. I wouldn't want to roll with him every day due to diminishing returns, but he's a very dangerous weapon to have at your disposal.
Don't forget, it's not just SB, he also excels greatly in the H category, where singles are as good as homers. And he's a good bet for 90+ R. He's very strong in 3 categories and only hurts you in SLG.
