Don Cooper's 'eyes lit up' watching White Sox prospect Michael Kopech

Don Cooper's 'eyes lit up' watching White Sox prospect Michael Kopech

There are bittersweet emotions because he's no longer Chris Sale's pitching coach, but Don Cooper is excited about the future of the White Sox.

The team's veteran pitching coach joined the White Sox Talk podcast on Tuesday and said even though he's sad see Sale go, it's hard to overlook the talent the team has received in return. Last month the White Sox traded their five-time All-Star to the Boston Red Sox in exchange for four prospects, including Michael Kopech. The club also added Lucas Giolito and two other pitching prospects in a trade for Adam Eaton. 

"When I saw Kopech, my eyes lit up," Cooper said. "Not only is he a big strong son of a gun, the stuff out of his hand is really good, life, energy stuff. He's just untapped talent right now. He's 20 years old. But he's already moved up the scale. 

"Delivery-wise it was like, 'Whoa.' Everything I like, he does. ...

"If he stays healthy he has a chance to be a killer."

Cooper also has high hopes for Giolito, baseball's top pitching prospect in 2016, who posted a 6.75 ERA in six big league games last season. He discounted Giolito's struggles as a small sample size and hopes to maximize the pitcher's talent.

"He still has his good stuff," Cooper said. "We've got to mix it up. We need more strikes. We need more consistency."

Cooper also noted that the stuff of Reynaldo Lopez, acquired with Giolito and Dane Dunning from Washington for Eaton, caught his eye. Combined with the pitching prospects already in the organization, Cooper thinks the White Sox have a talented farm system.

"Looking around, all of a sudden, combined with the younger pitchers we had in the system already, the injection of these guys that Rick (Hahn) has traded for, it's giving us a stronger, stronger system," Cooper said. "We’re amassing a lot of good talent."

Cooper said Sale is the most talented pitcher he's ever coached and he'll miss their everyday relationship. He described Sale as one of the 10 best pitchers on the planet. But Cooper hasn't been surprised by any moves since the White Sox allowed Mark Buehrle to leave via free agency. 

"It's sad that Chris is gone because my individual everyday relationship with him is over as a coach," Cooper said. "But the exciting thing is one of the reasons, the excitement of the guys you get back in return.

"It was mixed. 'Listen man, I'm sad you’re leaving because of that, the relationship. The everyday relationship is no longer there. We're friends.' I know this guy. I've seen every pitch in the big leagues he's thrown. 

"When you get to see every pitch and you're with them every single day and that relationship is over, it's sad in some ways. But this has happened before. It happened to Buehrle. If it can happen to Buehrle, it can happen to everybody."

Scouting reports on Yoan Moncada, Lucas Giolito and newly acquired White Sox prospects

Scouting reports on Yoan Moncada, Lucas Giolito and newly acquired White Sox prospects

The White Sox rebuild is in full effect.

Rick Hahn & Co. have traded Chris Sale and Adam Eaton in exchange for eight prospects in a span of two days.

Take a look at scouting reports for all eight players.

Yoan Moncada, 21, 2B — No. 1 prospect on MLB.com

(Acquired from Red Sox for Sale)

"Moncada brings a tantalizing blend of physicality, power, speed and athleticism as a switch-hitter with defensive versatility, making him one of the most dynamic prospects in the game. He projects as a plus offensive force, a plus defender at either second base or third base, and a plus runner capable of wreaking havoc on the basepaths. The one big area of his game that needs improvement is his plate discipline, which was exposed after he struck out 12 times in 20 plate appearances with the Red Sox. Despite that poor showing, he demonstrated patience throughout the minors and has shown a propensity for making quick adjustments before. He could start 2017 in Triple-A, but very well could break camp with the White Sox and solidify himself as a starter from day one in his new organization." — (Baseball America)

Lucas Giolito, 21, RHP — No. 3 prospect on MLB.com

(Acquired from Nationals for Eaton)

"The 2012 first-round pick and four-time BA Top 100 prospect made his long-awaited major league debut in 2016 but struggled, getting rocked for 26 hits and 16 earned runs in 21.1 innings, with more walks (12) than strikeouts (11). Giolito in the past sat in the upper 90s with his fastball and frequently reached triple-digits, but saw his stuff back up and sit in the 92-94 mph range and top out at 96 in 2016 with poor command. That fastball gave Giolito his biggest problems in 2016, with MLB opponents batting .349 against it with a .730 slugging percentage, per Statcast. While his fastball stalled, he still limited big league hitters to sub-.200 averages on his curveball (.167) and changeup (.143). The Tommy John survivor has seen his prospect stock fall in light of his recent struggles, but if he can rediscover his fastball velocity still projects as one of the most promising young righthanders in baseball. Scouts reported issues with his mechanics and pitchability this year, but both are correctable issues that should lead to improved command once they are solved." —​ (Baseball America)

Michael Kopech, 20, RHP — No. 30 prospect on MLB.com

(Acquired from Red Sox for Sale)

"Kopech is the latest in a long line of big, hard-throwing Texas righthanders, with a 98 mph fastball that routinely gets up to triple-digits and recently hit 102 in the Arizona Fall League. The 33rd overall pick in 2014 is more than just a thrower though, with an 87 mph power slider and 91 mph changeup that both made significant progress throughout the 2016 season and give him two quality offerings to confound batters even further. Taken on the surface, his raw stuff draws comparisons to Noah Syndergaard. Kopech does come with red flags, however. In 2015 he was suspended 50 games for amphetamine use and in spring training 2016 he broke his hand in an altercation with a teammate. If he can harness his talent without any more incidents, Kopech profiles as a possible No. 1 starter." —​ (Baseball America)

Reynaldo Lopez, 22, RHP — No. 38 prospect on MLB.com

(Acquired from Nationals for Eaton)

"Lopez entered 2016 as the Nationals’ second-best pitching prospect behind Giolito, but by the end of the year had surpassed him in the eyes of most evaluators. Lopez is just 6-foot, 185-pounds but possesses an electric 95-97 mph fastball that touched 100 in his major league debut in 2016, and backs it up with a low 80s curveball that grades plus, as well as an upper-80s changeup. Lopez’s biggest bugaboo is his command, which wavers at times and resulted in 4.5 walks per nine innings once he got to the majors. Still, the quality of his stuff allowed him to survive in both a relief and starting role once he got to Washington, and he gives the White Sox a young, major-league ready, power righthander to pair with lefties Jose Quintana—assuming he’s not traded—and Carlos Rodon." —​ (Baseball America)

Dane Dunning, 21, RHP

(Acquired from Nationals for Eaton)

"The Nationals drafted Dunning 29th overall this past June and signed him for $2 million after he was a core piece of Florida’s dominant pitching staff. Dunning bounced between starting and relieving in college but has the stuff to be a starter, with a low-90s fastball that gets up to 95 mph and a changeup and slider that both have a chance to be average. He demonstrated impeccable control at Florida and continued it with a 32-to-7 strikeout to walk mark over 33.2 innings in his pro debut. With strikeout stuff, plus control and a prime pedigree, Dunning has a chance to move quickly up the White Sox system and help sooner than later in Chicago." —​ (Baseball America)

Luis Alexander Basabe, 20, OF 

(Acquired from Red Sox for Sale)

"Basabe signed with the Red Sox along with his twin brother Luis Alejandro out of Venezuela when they were 16. They climbed the system together until this year, when Luis Alejandro was traded to the Diamondbacks midseason for Brad Ziegler. Now, Luis Alexander is on the move too after reaching high Class A as a 19-year old and solidifying himself as one of Boston’s top 10 prospects. He is a switch-hitter with the speed and athleticism to stick in center field, and his 25 stolen bases in 30 attempts last season are a testament to how his speed plays on the basepaths. Basabe is still very raw and refining his game, particularly his plate discipline and strike-zone judgement, but has shown the skill set to become a top of the order center fielder down the road." —​ (Baseball America)

Victor Diaz, 22, RHP

(Acquired from Red Sox for Sale)

"Diaz has a power fastball in the 96-100 mph range, an 87-90 mph slider that is his main secondary pitch, a riding two-seamer and a splitter in its nascent stages. He is still learning how to harness his arsenal after issuing 41 walks in his first 90 career innings. If he does that, he becomes a bona fide closer prospect down the road." —​ (Baseball America)
