No one knew what to expect from Yoan Lopez this season.
Despite a strong 10-game debut at the end of last season, in which he posted a 3.00 ERA, Lopez was someone the D-backs had in their back pocket and decided to give a play. Those 10 games only consisted of nine total innings.
Lopez is essentially a rookie this season. He has not pitched like one.
A nice surprise could be an understatement. Lopez signed with the D-backs in 2015 after playing three seasons in the Cuban league. He came over and initially struggled, posting a 4.72 ERA in his first two seasons in the minors, splitting time in Rookie ball and Double-A. Control was a huge issue; Lopez posted a 1.58 and 1.25 strikeouts per walk ratio in 2015 and 2016, respectively. A high home run rate (1.4 per nine) plagued him as well in 2016. He even left the organization after the season and planned to retire.
