The Astros made a big move on Saturday when they called up star prospect Kyle Tucker from Triple-A Fresno and sent down Jake Marisnick. Tucker may take a while to get comfortable in the big leagues, and we've seen this type of thing before. Alex Bregman had a very slow start to his career in the majors, and it looks like he's turned into a very good player. In fact, Bregman was named to his first All-Star team over the weekend. Bregman will join four other Astros at the All-Star game including Justin Verlander, Gerrit Cole, George Springer, and Jose Aluve.
