Siena Field has served as the home for the Saints' baseball team since the program began in the 1950s. In recent years, it has enjoyed several enhancements including new brick dugouts, chairback seating, a new infield and a new team clubhouse located behind the visitor's dugout. The field is positioned between the J. Spencer & Patricia Standish library and the Marcelle Athletic Complex, making it the majestic centerpiece of the scenic Siena campus.
In the summer of 2015, Siena Field began improvements. The renovations included a new seating system with stadium chair back and bleacher seating, a new press box with filming platform, new backstop (netting system), decorative entryway, outfield irrigation system to complement existing infield system, dugout repairs and safety netting, and enhanced storage space. Siena Field will continue with improvements as updates to all of the athletic facilities began in 2016. The field will be part of Phase 1B which took place during the 2016 fall and winter months with completion in 2018. The phase features a relocation and enrichment of the indoor baseball and softball hitting cages as well as the facilities storage area located on the south end of the MAC.
