A simple running suture may be either locked or left unlocked. The first knot of a running locked suture is tied as in a traditional running suture and may be locked by passing the needle through the loop preceding it as each stitch is placed (see the image below). This suture is also known as the baseball stitch because of the final appearance of the running locked suture line.
