Lithium abundances, determined for 120 subgiant stars in Lèbre et al. (1999), are analyzed and compared with predictions for dilution. To this purpose, the evolutionary status of the sample as well as the individual masses have been determined. We look for the distributions of A(Li) and Vsini with mass when those stars evolve along the subgiant branch. Our results bring a new light on the Lithium and rotation discontinuities in evolved phases.
