That shirt was visible while Lucas Giolito's younger brother, Casey, was being ... I guess you would call it "interviewed" by Bill Walton last week in Anaheim.
The T-shirt is right. The White Sox most definitely have an elite arm on their hands.
The elder Giolito brother, the All-Star pitcher and ace of the South Side starting staff, has bounced back from his post All-Star break bump in the road and returned to the dominant form that made him a Cy Young candidate in the first half.
Wednesday he turned in what was probably his finest performance of the season to date, silencing a Minnesota Twins team that lit him up for seven runs less than a month ago. This time through the menacing Twins lineup, Giolito tossed nine shutout innings, allowed just three hits, walked no one and struck out 12 batters. It was his third straight start with double-digit strikeouts, and he's got 36 of them in those three outings.
He was downright filthy Wednesday, keeping quiet a lineup that leads baseball in home runs and torched White Sox pitching for 14 runs just hours earlier on Tuesday night.
Wednesday's performance went hand in hand with his other shutout of the season, when he kept the Houston Astros from crossing home plate back in May. That night he was also excellent, but with fewer hits and walks allowed and more strikeouts against the Twins, I'll give the title of best outing of the year to Wednesday's.
Perhaps more impressive than anything, though, has been Giolito adding to the theme of this resurgent season, bouncing back when trouble has struck. It's the general transformation that's taken him from the highest ERA among qualified starters in 2018 to an All Star this season. Both Giolito and catcher James McCann have noticed one of the biggest differences being that early damage in games doesn't rattle him like it did last season. And now we have Giolito erasing a less-than-ideal stretch to return to dominant form.
Giolito's ERA was down to 2.22 after six innings of one-run ball against the New York Yankees on June 14. In the seven starts that followed, his ERA exploded to 3.52 thanks to a 6.38 ERA in those seven outings. He gave up 26 runs and 39 hits in those 36.2 innings. He's responded phenomenally, with a 2.12 ERA in his last six starts, a stretch that's featured 53 strikeouts and just nine walks in 34 innings. His season ERA stands at 3.20.
For any who might be skeptical that this is the pitcher Giolito will be for years to come, that's a pretty good sign.
In general, there seems to be a good deal of skepticism surrounding how the White Sox rotation will fare in 2020, and much of it is plenty warranted. Michael Kopech will be coming off Tommy John surgery with just four major league starts under his belt. Reynaldo Lopez has been mostly excellent since the All-Star break but had a miserable first half. Dylan Cease has struggled from a results standpoint in his brief big league tenure, with a 5.93 ERA in eight starts. And until the White Sox start making moves this winter, we don't even know who will occupy that fifth spot.
But Giolito is doing his best to show that he can be relied on to be a force at the top of that rotation. Performances against two of the best teams in baseball, the Astros and Twins, have been the biggest exclamation points on that statement to date.
It wouldn't be surprising, though, to hear that "reliable" isn't enough for him. It's not "G-Reliable-O," after all.
