When rookie shortstop Gordon Beckham arrived on the South Side, he had a quick start which propelled him into the "can't miss" category. In 2009, he hit .270, 14 HR and 63 RBI with a 2.1 WAR. Sadly, that was his best major league season. He went to play second full time, and was a Gold Glove caliber defender.
But after 5.5 years with the Sox, Beckham batted only .244, 61 HR, 276 RBI and 5.9 WAR. The "can't miss" prospect with the confidence to be an All-Star turned into a "can't hit" major leaguer.
Beckham's case is not unusual. Less than six percent of all minor leaguers make it to the majors, and very few have All-Star caliber careers. Beckham is the latest example of how an accomplished minor league prospect can make an initial splash in the Show, but fail to have a good career.
So the White Sox traded Beckham to the Angels for a player to be named or cash.
Beckham lasted longer than the Cubs Brett Jackson, who was also traded this summer for nominal return. Jackson was a highly anticipated five tool centerfielder who could be a cornerstone player for the Cubs for a decade. His major league career lasted only 44 games.
Even today, highly regarded prospect Javy Baez is wowing the crowds with massive home runs. But Baez also is a strike out mess (being punched out more than 43 percent). In his first 17 games, Baez has hit 5 home runs, but struck out 30 times. He is only hitting .214. It is feast of famine. It is almost an exact repeat of Jackson's struggles.
Even players who have a good track record can begin to falter for no apparent reason. Travis Wood's last outing against the rain soaked Giants was termed "an Edwin start," a Cub term of art for a bad performance. Wood's performance has become to noticeably slide from his excellent 2013 season (4.4 WAR) to this year (negative 0.4 WAR).
Even the best prospects may only give a team a slight, one year jolt in performance. The lesson is clear: there is still a major leap from AAA to the majors. More than 90 percent of those prospects don't make a long term career out of their opportunity.
