Above are the fastest times that Marshall Anderson has achieved in his swimming career. For each event, you can find Marshall's best time, the corresponding time standard, as well as how much faster Marshall needs to be to reach the next level. The last columns provide Marshall rankings at the team and LSC levels. These rankings are based on the Marshall's personal best, his current age category, and team; and are calculated from all the meets results.
