"I'd say in the first inning, I did an OK job of commanding a curveball for a strike," Giolito said. "I feel like when I throw it for a strike and can show I can throw it for a strike, that's when I can get more swings on it.
"The second inning, I kind of got away from it. I was kind of yanking them, throwing a lot in the dirt low and away, and a big league hitter is just going to spit on that. I'm just going to continue to work on that, throwing a curveball for a strike, commanding a fastball especially down and away to righties."
Giolito admitted that the adrenaline rush from the packed stadium made him a little quick and ahead of himself, missing with the four-seam fastball.
"My biggest things are throwing a curveball for a strike, being able to differentiate throwing it for a strike and throwing the good one down for a put-away pitch, and then commanding fastballs to both sides of the plate," Giolito said. "I'll have plenty more opportunities, a lot of stuff to work on in the spring."
Frazier getting in the swing of things
Todd Frazier took about 35 swings and fielded 35 ground balls Monday morning at Camelback Ranch to test the mild oblique strain on his left side. Frazier felt good after the test.
"Full go, felt great," said Frazier, who has been out of action since last Monday. "Slow process, no rush."
Frazier wants to see how he responds Tuesday before he starts thinking about a return to game action. But he's focusing on hitting full stride by late March to be ready for the regular season.
• Renteria said that Zack Collins, the White Sox top pick in the 2016 MLB Draft and No. 6 White Sox prospect, per MLBPipeline.com, could start one of the two games in Tuesday's split-squad action. Collins picked up his second Spring Training hit on Monday, both singles.
• Jose Abreu left Arizona for Miami following Monday's game to tend to personal matters. He is expected back Wednesday.
