Chicago White Sox rookie starter Michael Kopech was pitching fine until the fourth inning of Wednesday's game against the Detroit Tigers. In that inning, Kopech allowed six hits, three home runs, and six runs before being yanked. He finished with a line of 3 1/3 innings, allowing seven runs on nine hits, with one walk and six strikeouts. Kopech has started his Major League career on a high note, but simply struggled with command on Wednesday. The disastrous inning put his season ERA up to 5.02, even though he only allowed one run in his 11 innings prior to this game. He has a great matchup against the Kansas City Royals next Tuesday and should be started with moderate confidence.

Kopech (1-1) took the loss Wednesday as the Tigers tamed the White Sox 10-2, coughing up seven runs on nine hits -- including four home runs -- and a walk over 3.1 innings while striking out six.

Chicago White Sox pitching prospect Michael Kopech received a big vote of confidence on Thursday. The team's player development director Chris Getz said, "We have a chance to see him [in Chicago in 2018]. He's going to find his way to [the] big leagues. I'm very confident he's going to be a frontline-type starter." Getz mentioned Kopech's command of his fastball as a key to his progression. Kopech has struggled with his control this season. He walked four in his most recent game but struck out six. All in all, dynasty owners waiting for Kopech to make the leap have to be pleased with this recent news. If his control issues get better, the highly-touted prospect might be entering the relevant fantasy radar sooner rather than later.

Kopech allowed five runs on two hits and a season-high eight walks for Triple-A Charlotte on Thursday.

Chicago White Sox pitching prospect Michael Kopech allowed eight walks Thursday evening for Triple-A Charlotte. Kopech only went three innings in the contest and allowed two hits and five runs. He also struck out two. Kopech has cooled off since his hot start to the season and has had command issues with 20 walks over his last five starts. Kopech remains one of the more exciting pitching prospects in the game due to his ability to touch 100 mph on the radar gun, but he will need better command before the White Sox promote him to the big leagues. General manager Rick Hahn spoke earlier in the week and said the White Sox would be patient and do what's best for the development of their top prospects. Kopech should debut in 2018, but it is unlikely to be as soon as fantasy owners would like. He remains a nice stash in redraft leagues and should already be owned in dynasty leagues.

Kopech allowed two runs on five hits and five walks while striking out 10 over six innings for Triple-A Charlotte on Friday.

Chicago White Sox top pitching prospect Michael Kopech had a rough outing Saturday for Triple-A Charlotte. In two innings he allowed seven runs on five hits. He also allowed four walks while striking out two hitters. Kopech has struggled of late and his ERA was raised to 4.89 after the rough outing. He remains one of the best pitching prospects and should offer good strikeout numbers when he does reach the big leagues. Kopech is a strong stash in all formats as he should be up with the White Sox at some point this season.

Chicago White Sox starting pitching prospect Michael Kopech is likely headed for a mid-July call-up to the Majors, according to the Daily Herald's Scot Gregor. Kopech, 22, has been pitching this season for AAA Charlotte in the International League. Kopech has made seven starts for Charlotte, posting a 0-2 record with a 4.86 ERA. However, he's been unlucky, as evidenced by his 3.59 FIP. Kopech has great strikeout stuff, as shown by his 11.9 K/9 ratio this season, but he still has an opportunity to work on his control, as he's currently averaging 4.6 walks per nine innings. Given this news, Kopech might be worthy of a stash in deeper redraft leagues. He's a dynasty league stud.

The Chicago White Sox, who currently sit in last place in the American League Central, are in no hurry to rush outfield prospect Eloy Jimenez and pitching prospect Michael Kopech to the big leagues. It appears that the White Sox want to make sure that when Jimenez and Kopech are called up, that they are up for good. Jimenez is hitting a whopping .320 with seven home runs and 25 home runs in just 103 at-bats for Double-A Birmingham. Kopech has 44 strikeouts in 33 1/3 innings with a 4.86 ERA for Triple-A Charlotte. Both Kopech and Jimenez should be up at some point in 2018, but it is unlikely to happen as soon as expected.

Kopech allowed two runs on one hit and four walks while striking out three for Triple-A Charlotte on Sunday.
