Lopez allowed one run on three hits and one walk while striking out three over three innings in Sunday's game against Arizona.
The right-hander was much better in his second Cactus League start than his first last Tuesday, when he allowed five runs and four hits in 1.1 innings. Lopez said he was much more focused Sunday and was able to keep his pitches down in the zone. He's expected to open the 2017 at Triple-A Charlotte with a trip up to Chicago at some point during the regular season a real possibility.
