UML use case diagram - Project administrator

"A project manager is the person responsible for accomplishing the stated project objectives. Key project management responsibilities include creating clear and attainable project objectives, building the project requirements, and managing the constraints of the project management triangle, which are cost, time, scope, and quality.
A project manager is often a client representative and has to determine and implement the exact needs of the client, based on knowledge of the firm they are representing. A project manager is the bridging gap between the production team and client. So he/ she must have a fair knowledge of the industry they are in so that they are capable of understanding and discussing the problems with either party. The ability to adapt to the various internal procedures of the contracting party, and to form close links with the nominated representatives, is essential in ensuring that the key issues of cost, time, quality and above all, client satisfaction, can be realized.
The term and title 'project manager' has come to be used generically to describe anyone given responsibility to complete a project. However, it is more properly used to describe a person with full responsibility and the same level of authority required to complete a project. If a person does not have high levels of both responsibility and authority then they are better described as a project administrator, coordinator, facilitator or expeditor." [Project manager.

"Baseball is played between two teams with nine players in the field on each team. On a baseball field, the game is under authority of several umpires. There are usually four umpires in major league games; up to six (and as few as one) may officiate depending on the league and the importance of the game. There are four bases. Numbered counterclockwise, first, second and third bases are cushions (sometimes informally referred to as bags) shaped as 15 in (38 cm) squares which are raised a short distance above the ground; together with home plate, the fourth "base," they form a square with sides of 90 ft (27.4 m) called the diamond. Home base (usually called home plate) is a pentagonal rubber slab 17 in (43.2 cm) wide. The playing field is divided into three main sections:
(1) The infield, containing the four bases, is for general defensive purposes bounded by the foul lines and within the grass line (see figure).
(2) The outfield is the grassed area beyond the infield grass line between the foul lines, and bounded by a wall or fence.
(3) Foul territory is the entire area outside the foul lines.
The pitcher's mound is located in the center of the infield. It is an 18 ft (5.5 m) diameter mound of dirt no higher than 10 in (25.4 cm). Near the center of the mound is the pitching rubber, a rubber slab positioned 60 ft 6 in (18.4 m) from home plate. The pitcher must have one foot on the rubber at the start of every pitch to a batter, but the pitcher may leave the mound area once the ball is released." [Baseball rules. Wikipedia]
