Francisco Peguero could see the big leagues again this season.
Two pitchers who have spent some time on this list continued to struggle last week for Fresno.
Michael Kickham is now 0-2 with a 7.13 ERA over four starts after giving up six runs in four innings on Sunday.
Chris Heston gave up five runs in five innings of work in his last start. His ERA is now 6.58 on the year. If the Giants need a sixth starter this season, they're probably going to have to go outside the organization to find one.
Reliever Dan Runzler has pitched well for Fresno this year. He's put up an 0.93 ERA and struck out 11 against three walks in 9.2 innings of work.
Francisco Peguero saw his first big league action for the Giants last season, and he could get another shot this year. He's hitting .429 over 12 games thus far for Fresno.
Roger Kieschnick could also warrant a look in left filed for the Giants this season. He's hitting .337/.356/.663 with four home runs so far this season for Fresno.
Adalberto Mejia is another impressive young arm in the stacked San Jose rotation. The 19-year-old lefty is 2-0 with a 4.19 ERA in four starts this season.
San Jose reliever Bryce Bandilla has struck out 29 of the 56 hitters he's faced this season in just 13.2 innings pitched.
