The three best pitchers in the National League in 1988 were Orel Hershiser, Danny Jackson, and David Cone. No ifs, ands, or buts. But at the break, it was not so clear-cut. Pittsburgh pitcher Bob Walk had ten victories at the break along with a 2.47 ERA, while Hershiser sat at 13 wins/2.62 ERA, Jackson at 10/3.28, and Cone at 9/2.52. However, the latter three ended the season with at least 20 wins, while Walk was only able to muster two more victories in 1988.
Still, at the break, Walk was in the mix for best pitcher in the National League. and he was rewarded with a trip to Cincinnati for the All-Star Game.
