Although Chris Sale is the unquestioned ace of the White Sox staff, Tuesday's starter, 25-year-old left-hander Jose Quintana, has been putting up solid numbers outside the spotlight.
Quintana has only a 6-9 record, but he has a 3.14 ERA and 2.88 FIP (fielding independent pitching). In his last 11 starts, he is 3-2 with a 2.15 ERA.
In his most recent outing, he carried a two-hit shutout into the seventh inning, but an overturned call that resulted in catcher Tyler Flowers being charged with obstruction of home plate led to a seven-run inning for the Giants. Quintana finished the game with 6 2/3 innings pitched and four runs allowed.
His opponent, Chris Tillman, is also on a roll, which has proved important for the Orioles' division title hopes as they aim to hold their 7 1/2-game lead over the second-place Yankees.
Since giving up five runs in only one inning against the Rangers on June 5, Tillman is 4-3 with a 2.42 ERA, and opponents are hitting only .218 off him.
Tillman's season ERA peaked after that start, reaching 5.20, but since then he has lowered the mark to 3.68.
White Sox: De Aza picking up at the plate
Alejandro De Aza spent most of the first two and a half months of the season hovering around the proverbial "Mendoza" line, with his batting average fluctuating between the high .100s and low .200s.
But in the last few weeks, he has picked up the pace and is hitting better than he has all season. His average, which was at .196 as late as June 17, is up to .247.
"He'll be in there the majority of the time," manager Robin Ventura said. "I think that's just where we're at right now, being able to find him at-bats, and Dayan [Viciedo] the same thing. To where he was in April to where he's at now, he's been on a good stretch."
Orioles: Gonzalez working toward return
Pitcher Miguel Gonzalez remins on track to rejoin the team later this week after throwing a simulated game on Monday.
"[He threw] 75 pitches," manager Buck Showalter said. "Did a lot of offensive work, too. It was a good workday for him; got a lot done. He said he's ready to do what we might need."
Gonzalez, who had a 3.80 ERA in 20 games (19 starts) for the Orioles this season, could throw a side session while he is with Double-A Bowie.
The 30-year-old right-hander has a 3.64 ERA in 68 career Major League games. Showalter said Gonzalez could be back in the Majors shortly.
"If it looks like we are going to have a need in the bullpen, he probably wouldn't [take his side day]," Showalter said. "But if we get to that point where it looks like we are going to be able to get through the off-day without a need, then he probably would take it there."
• White Sox outfielder Adam Eaton threw from 120 feet and took dry swings on Monday as part of his rehab while working his way back from a strained right oblique.
"Even today, looking at him running around and doing stuff, it is progressing," Ventura said. "He was swinging lightly enough that it looks like it's getting better."
