MARYVALE, Ariz. — Even after posting a 2.68 ERA in 46 games last season, Matt Lindstrom thinks there’s room for improvement.

Shortly after Lindstrom signed a 1-year contract with the White Sox in January, he quickly informed pitching coach Don Cooper what he wanted to work on this spring.

From the first day of spring workouts, Cooper, bullpen coach Bobby Thigpen and minor league pitching coordinator Curt Hasler have examined Lindstrom’s landing spot to help him better command his fastball, which was once clocked as fast as 100 mph and averages 96.
