Your 1958 San Francisco Giants

The San Francisco Giants did not have a set lineup in their inaugural 1958 season as they featured several rookie callups midseason and platoons at more than one position.  I will list their Opening Day lineup then other key position players, starting rotation and bullpen.  As I mentioned in the Stu Miller post, they had several "swingman" pitchers who functioned as a "committee" for the #4 and #5 starting pitchers.

Opening Day Lineup:

Jim Davenport 3B     .256/.343/.406, 22 2B, 3 3B, 12 HR, 70 R, 41 RBI, 493 PA.
Jim King LF               .214/.343/.393, 2 2B, 3B, 2 HR, 8 R, 8 RBI, 66 PA.
Willie Mays CF          .347/.419/.583, 33 2B, 11 3B, 29 HR, 31 SB, 121 R, 96 RBI, 685 PA.
Willie Kirkland RF    .258/332/.447, 25 2B, 6 3B, 14 HR, 3 SB, 48 R, 56 RBI, 470 PA.
Orlando Cepeda 1B   .312/.342/.512, 38 2B, 4 3B, 25 HR, 15 SB, 88 R, 96 RBI, 643 PA.

As you can see, Willie Mays and Orlando Cepeda carried the main offensive load.  Leon Wagner provided an offensive boost after his callup and Hank Sauer still had some thump left in his bat. The most striking thing about the roster, to me, was the versatility of the pitching staff.  Whether that was the best way to use them is an interesting question.
