Chris Volstad and Hector Santiago combined for one of the best outings by a White Sox starting pitcher this season.
These weren't the names anyone expected to fit that description when the season began. But with struggles all around from James Shields, Lucas Giolito, Miguel Gonzalez and Carson Fulmer, here the White Sox sit as they approach the one-month mark of the 2018 campaign.
Reynaldo Lopez has been excellent, no doubt about it, and Fulmer has turned in a couple nice outings, including in Monday's win over the visiting Seattle Mariners. But against that same M's lineup Tuesday afternoon, Volstad - who lasted 4.1 innings in a 1-0 loss - became the first White Sox starter this season not to issue a walk.
It was an important outing for Volstad, as well as for Santiago, who followed him up with 3.1 shutout innings of his own. The duo showed they're both capable of serving as reliable fill-ins in a White Sox rotation that got a hole punched in it Monday, when Gonzalez went to the disabled list.
Shields, Giolito, Lopez, Fulmer. Those guys aren't going anywhere. But should Gonzalez remain on the DL for an extended period of time, it doesn't seem as if the White Sox need to be searching for options.
"Volstad and Hector both did a nice job. I thought they gave us plenty of outs, they gave us plenty of opportunity," manager Rick Renteria said after Tuesday's game.
But that doesn't mean the South Siders are out of the starting-pitching woods for the remainder of this week. Shields will go in Wednesday's finale with the Mariners. Giolito and Lopez are set to pitch in the first two games of a five-game road series against the Kansas City Royals on Thursday and Friday, respectively.
But Saturday presents a mystery, one that doesn't seem to have an easy answer.
Thanks to that opening-weekend snow-out, there's a doubleheader Saturday, and while Fulmer is in line to start one of those games, who will start the other? The White Sox will get a 26th man for that day, and that spot is typically given to a spot starter brought up from Triple-A. But given the White Sox current situation on the 40-man roster, there aren't many options, meaning a player might need to be outrighted in order to make room for a spot starter.
Let's get this out of the way first: It seems unlikely that Michael Kopech will make his major league debut in a spot start during an April doubleheader in Kansas City. Yes, Kopech has been good in his three starts with Charlotte, sporting a 2.40 ERA with 21 strikeouts. But he's got just six total starts at the Triple-A level, and the White Sox have made it abundantly clear throughout the last several months that the necessities of the big league team during this rebuilding season and Kopech's readiness for the majors are independent of one another.
It makes no sense to potentially cut short Kopech's development at the Triple-A level because the big league rotation needs a spot starter.
The options, however, are limited.
Of the seven players who have started games for the Knights this season, two are on the big league roster right now (Volstad and Chris Beck), one is Kopech and one has a 9.75 ERA (T.J. House). One is on the 40-man roster, Ricardo Pinto, who made his first start at Charlotte on Tuesday. Pinto, though, would be on short rest Saturday.
The other two are Dylan Covey, who turned in a 7.71 ERA with the White Sox last season, and Donn Roach, who has made two career major league starts, most recently giving up four runs in 3.1 innings in a spot start for the Cubs in 2015. Covey and Roach have 2.95 and 1.88 ERAs at Charlotte, respectively. But the White Sox would need to make room on the 40-man roster to bring either up, even just for a day.
While it would be on "short rest," perhaps the most logical option is just to start Volstad or Santiago on Saturday and start the other on Sunday. Tuesday, Volstad threw 66 pitches and Santiago threw 59 pitches, neither total approaching the qualification of a heavy workload, especially considering both veterans have plenty of starting experience under their belts.
Renteria talked about how well it worked using both guys in tandem Tuesday, but he might have to split them up to staff his rotation this weekend. It would also eliminate the need to remove someone from the 40-man roster. The White Sox could just bring up another bullpen arm as the 26th man, someone like Juan Minaya, who was on the Opening Day roster.
Renteria has already shown willingness to use his pitchers outside of the traditional "every fifth day" strategy. Shields and Fulmer both pitched in back-to-back games just last week. And Fulmer's turn was moved up when Gonzalez went on the DL, pressing him into his third appearance in six days Monday.
The mystery likely won't be solved, at least publicly, anytime soon. We'll likely have to wait a few days to know for sure. Until then, it's a guessing game.
