There are three types of rosters used by Major League baseball teams and each has its own unique set of characteristics.

The Active roster lists the 25 players eligible to participate in a specific game and cannot be changed once the game begins. Clubs alter this roster by moving players to the Disabled List, designating them for assignment, sending them down to the minors and occasionally out-righting them completely.

The Major League roster contains all players under major league contract and high profile minor leaguers. This roster is limited to 40 players. Teams have to handle this properly or risk losing players to another team or free agency. Whenver a player is added to this roster, another player must be dropped.

Finally, beginning September 1 of each year, the Active roster, now an Expanded Roster can be increased and is used to add players with special skills to help in a pennant race, key Minor Leaguers the team wants to see at the major league level or any number of other team designated reasons. When post season play begins, the Expanded Roster is no longer in effect and the Active Roster again is limited to 25 players.

In a normal season most teams carry 2 catchers, 5 or 6 infielders, 4 or 5 outfielders, 5 starting pitchers, 1 closer and cap off the roster with relief pitchers. The makeup of the rosters vary by league and team. With the American League using a designated hitter, it allows them to roster more pitchers, while the National League must concern itself with carrying additional position players. The utility player is very important in baseball, but more so in the National League.http://www.baseball-reference.com/bullpen/Roster

In 1968, the Tiger's Left/Right pitching combination of Mickey Lolich and Danny McLain was electric. McLain won 31 games (the last pitcher to win 30), with an ERA under 2. Lolich hurled the team to 3 wins in the World Series, including the series clincher against the St. Louis Cardinals. In over 300 innings, McLain sported a WHIP under 1. Combine that with 28 complete games and 280 Ks and you have probably the most dominating single season American League pitching performance of the last 50 years. As a side note, McLain allowed only 73 earned runs. Of those, 31 were Home Runs, limiting the opportunities for rallies. Lolich, in 100 less innings pitched K'd 197 batters, leaving him just short of the coveted 200 mark.
