3) Former Padres pitcher Julio Teheran proved his cold spring was a fluke
The Padres had two cracks at this. They signed Julio Teheran to a minor league deal this offseason, and after opting out, re-signed him to another minors deal. The Padres do have a lot of pitching depth, but it's possible that his rough Spring Training is why they let the veteran sign a deal with the Milwaukee Brewers.
Teheran posted a 5.17 ERA in five appearances (three starts) and 15.2 innings of work this spring. Not exactly what you want to see, but there were some good signs hidden behind the ugly ERA. Teheran struck out 16 batters which is more than one an inning, while walking just two. While he gave up a home run and 16 hits, his impeccable command was promising.
Teheran did not make the Opening Day roster as expected, and did not pitch very well in the minors before the Brewers snatched him. Ever since getting his chance in Milwaukee, Teheran has been lights out.
The right-hander has an ERA of 1.53 through his first six starts and 35.1 innings pitched. He's allowed two runs or fewer in each one of his starts, with four of the six coming against teams that are currently above .500. His last time out saw him deliver five shutout innings against the first place Diamondbacks.
The Padres rotation is not the main reason why this team has underperformed, but it wouldn't hurt to have this guy putting up these numbers pitching every fifth or sixth day.
