After being drafted by the Pirates second overall in 1986, and developing in Montreal under manager/father Felipe Alou, Moises had his breakout season in 1994, hitting .339 with 22 HR, earning him a spot in the All-Star Game.

Montreal let him go as a free agent in 1996, and he signed with the Florida Marlins, where he helped that club win the 1997 World Series.

Marlins owner Wayne Huizenga immediately dismantled his championship club amid the howls of South Florida fans, holding a fire-sale of talent, and trading Alou to the Astros in the process.

Alou made an immediate contribution to the 1998 Astros, helping that club to a franchise-best 102 wins, and earning him another trip to the Mid-Season Classic.

Always injury-prone, he missed the entirety of the 1999 season after falling off a treadmill in the off-season, and missed a significant portion of 2000 and 2001 as well. Still, after escaping the cavernous Astrodome for hitter-friendly Enron Field in 2000, he hit .355 with 30 HR, and appeared in the 2001 All-Star Game.

The budget-conscious Astros, in a move that was hotly debated among fans at the time, allowed him to become a free agent after the 2001 season. Alou then signed with the Cubs, but his mediocre performance there in 2002 seems to have vindicated the Astros' front office... for now.

Moises is the cousin of Mel Rojas, the nephew of Matty Alou and former Astro Jesus Alou, and, of course, the son of Felipe Alou.
