The MLB All-Star break has come and gone, and plenty of the league's stars just recharged in order to continue their phenomenal seasons. However, there are a few players who were expected to enjoy great success in 2019 who couldn't manifest it in the first half of the year. However, for these five players, there's a good chance that they bust out of their slumps in the second half.

5. Matt Carpenter, St. Louis Cardinals

Carpenter has put together a very uncharacteristic .216/.325/.381 slash line with just 10 homers through the first half of the season. While he may not hit for average, he could easily experience a power surge, something that typically arrives for him in the second half of the year. He hasn't hit fewer than 21 home runs since 2014, so expect the power to come back for Carpenter as he returns from the IL, just in time for the Cardinals to chase a playoff spot.

4. Robinson Cano, New York Mets

The All-Star break could not have come at a worse time for Cano, as he had raised his batting average nearly 20 points in the previous week. While it may seem like a stretch, we can't forget that Cano has always been a great hitter, even after his suspension last year, hitting .317 with six homers in the second half of the year. If Cano can start hitting again, things could start looking up for the Mets down the stretch.

3. Paul Goldschmidt, St. Louis Cardinals

Goldschmidt's first season in St. Louis is clearly not going according to plan, as he's having his worst season of his career.
