No. 3: Emmet Sheehan
Sheehan had some inconsistency issues at the MLB level, but definitely did show flashes of why he could become a quality MLB starting pitcher in the future. Sheehan's stint with the Dodgers started off with six no-hit innings against the Giants, and although he gave up two home runs in his next start against the Astros, both homers were solo shots and ended up being the only runs he surrendered. The Rockies scored three runs against him in five innings at Coors Field (but it is Coors Field, after all), meaning that his first three starts with the Dodgers ended with 17 innings pitched, a 2.65 ERA and 12 strikeouts. Then, things went south for Sheehan, as his ERA climbed in three consecutive starts. He gave up five, four and eight earned runs to Pittsburgh, Baltimore and Texas, respectively.
Sheehan was better in his final two starts in the majors, however, pitching five shutout innings against the Reds, where he struck out five and gave up just two hits, and following that up with four innings against the A's where the only blemishes were two solo homers, just like his start against the Astros.
Sheehan was optioned to Triple-A as the Dodgers made room for both Lance Lynn and Clayton Kershaw (who was returning from the IL soon after Sheehan's last appearance). In his first Triple-A appearance, Sheehan fanned six, while his only earned run allowed was a solo homer over the course of four innings (sound familiar?). In his next outing, he gave up just one walk and one hit, striking out five in four scoreless innings.
