Now, they're all playing minor league baseball.
Here is a look at how each of them has started their respective professional careers after a few weeks of play.
For the record, all four are off to solid starts.
Schwarber, who was the fourth pick overall in the draft by the Chicago Cubs, continues to tear it up. In six games in Rookie ball at Boise, Schwarber went 12-for-20 with four home runs and 10 RBI. The start earned him a quick promotion to Class A Kane County in Geneva, Ill. In 14 games there, Schwarber is 19-of-49 with five doubles, no triples, four home runs and 11 RBI. He's hitting at a .388 clip. In one game he had two home runs and five RBI. Overall for the minors, Schwarber is hitting .449 with six doubles, one triple, eight home runs and 21 RBI.
Travis, a second round pick of the Boston Red Sox, has bounced back from a tough start with the Lowell (Mass.) Spinners in the New York-Penn League in Class A Short Season play. He started 1-for-13 at the plate. Now, he's hitting .305 in 15 games. He is 18-of-59 with one double, no triples, two home runs and eight RBI. In the last five games, he has really started hitting the ball, going 9-for-20.
DeMuth, a fifth round pick of the Brewers, is playing rookie league ball in Helena (Mt.) in the Pioneer League. The former IU standout is hitting .403 as he has gone 25-for-62 in 15 games. He has three doubles, one triple, one home run and six RBI.
DeNato, a 19th round pick by the Phillies, is playing for Williamsport (Pa.) in the same league as Travis. He has pitched in six games, all in relief. He earned his first win on July 1 and is 1-0 with a 3.68 ERA. In his last three appearances he has not surrendered an earned run.
